After this, The Empress asked them, What kind of substance or creature the Air was? The Bird-men answered, That they could have no other perception of the Air, but by their own Respiration: For, said they, some bodies are onely subject to touch, others onely to sight, and others onely to smell; but some are subject to none of our exterior Senses: For Nature is so full of variety, that our weak Senses cannot perceive all the various sorts of her Creatures; neither is there any one object perceptible by all our Senses, no more then several objects are by one sense. I believe you, replied the Empress; but if you can give no account of the Air, said she, you will hardly be able to inform me how Wind is made; for they say, that Wind is nothing but motion of the Air. The Bird-men answer'd, That they observed Wind to be more dense then Air, and therefore subject to the sense of Touch; but what properly Wind was, and the manner how it was made, they could not exactly tell; some said, it was caused by the Clouds falling on each other; and others, that it was produced of a hot and dry exhalation: which ascending, was driven down again by the coldness of the Air that is in the middle Region, and by reason of its leightness, could not go directly to the bottom, but was carried by the Air up and down: Some would have it a flowing Water of the Air; and others again, a flowing Air moved by the blaz of the Stars.

But the Empress, seeing they could not agree concerning the cause of Wind, asked, Whether they could tell how Snow was made? To which they answered That according to their observation, Snow was made by a commixture of Water, and some certain extract of the Element of Fire that is under the Moon; a small portion of which extract, being mixed with Water, and beaten by Air or Wind, made a white Froth called Snow; which being after some while dissolved by the heat of the same spirit, turned to Water again. This observation amazed the Empress very much; for she had hitherto believed, That Snow was made by cold motions, and not by such an agitation or beating of a fiery extract upon water: Nor could she be perswaded to believe it until the Fish- or Mear-men had delivered their observation upon the making of Ice, which, they said, was not produced, as some hitherto conceived, by the motion of the Air, raking the Superficies of the Earth, but by some strong saline vapour arising out of the Seas, which condensed Water into Ice; and the more quantity there was of that vapour, the greater were the Mountains of Precipices of Ice; but the reason that it did not so much freeze in the Torrid Zone, or under the Ecliptick, as near or under the Poles, was, that this vapour in those places being drawn up by the Sun-beams into the middle Region of the Air, was onely condensed into Water, and fell down in showres of Rain; when as, under the Poles, the heat of the Sun being not so vehement, the same vapour had no force or power to rise so high, and therefore caused so much Ice, by ascending and acting onely upon the surface of water.

This Relation confirmed partly the observation of the Bird-men concerning the cause of Snow; but since they had made mention that that same extract, which by its commixture with Water made Snow, proceeded from the Element of Fire, that is under the Moon: The Emperess asked them, of what nature that Elementary Fire was; whether it was like ordinary Fire here upon Earth, or such a Fire as is within the bowels of the Earth, and as the famous Mountains Vesuvius and Ætna do burn withal; or whether it was such a sort of fire, as is found in flints, &c. They answered, That the Elementary Fire, which is underneath the Sun, was not so solid as any of those mentioned fires; because it had no solid fuel to feed on; but yet it was much like the flame of ordinary fire, onely somewhat more thin and fluid; for Flame, said they, is nothing else but the airy part of a fired Body.

Lastly, the Empress asked the Bird-men of the nature of Thunder and Lightning? and whether it was not caused by roves of Ice falling upon each other? To which they answered, That it was not made that way, but by an encounter of cold and heat; so that an exhalation being kindled in the Clouds, did dash forth Lightning, and that there were so many rentings of Clouds as there were Sounds and Cracking noises: But this opinion was contradicted by others, who affirmed that Thunder was a sudden and monstrous Blaz, stirred up in the Air, and did not always require a Cloud; but the Empress not knowing what they meant by Blaz (for even they themselves were not able to explain the sense of this word) liked the former better; and, to avoid hereafter tedious disputes, and have the truth of the Phænomena's of Cœlestial Bodies more exactly known, commanded the Bear-men, which were her Experimental Philosophers, to observe them through such Instruments as are called Telescopes, which they did according to her Majesties Command; but these Telescopes caused more differences and divisions amongst them, then ever they had before; for some said, they perceived that the Sun stood still, and the Earth did move about it; others were of opinion, that they both did move; and others said again, that the Earth stood still, and Sun did move; some counted more Stars then others; some discovered new Stars never seen before; some fell into a great dispute with others concerning the bigness of the Stars; some said, The Moon was another World like their Terrestrial Globe, and the spots therein were Hills and Vallies; but others would have the spots to be the Terrestrial parts, and the smooth and glossie parts, the Sea: At last, the Empress commanded them to go with their Telescopes to the very end of the Pole that was joined to the World she came from, and try whether they could perceive any Stars in it: which they did; and, being returned to her Majesty, reported that they had seen three Blazing-Stars appear there, one after another in a short time, whereof two were bright, and one dim; but they could not agree neither in this observation: for some said, It was but one Star which appeared at three several times, in several places; and others would have them to be three several Stars; for they thought it impossible, that those three several appearances should have been but one Star, because every Star did rise at a certain time, and appear'd in a certain place, and did disappear in the same place: Next, It is altogether improbable, said they, That one Star should fly from place to place, especially at such a vast distance, without a visible motion; in so short a time, and appear in such different places, whereof two were quite opposite, and the third side-ways: Lastly, If it had been but one Star, said they, it would always have kept the same splendor, which it did not; for, as above mentioned, two were bright, and one was dim. After they had thus argued, the Empress began to grow angry at their Telescopes, that they could give no better Intelligence; for, said she, now I do plainly perceive, that your Glasses are false Informers, and instead of discovering the Truth, delude your Senses; Wherefore I Command you to break them, and let the Bird-men trust onely to their natural eyes, and examine Cœlestial Objects by the motions of their own Sense and Reason. The Bear-men replied, That it was not the fault of their Glasses, which caused such differences in their Opinions, but the sensitive motions in their Optick organs did not move alike, nor were their rational judgments always regular: To which the Empress answered, That if their Glasses were true Informers, they would rectifie their irregular Sense and Reason; But, said she, Nature has made your Sense and Reason more regular then Art has your Glasses; for they are meer deluders, and will never lead you to the knowledg of Truth; Wherefore I command you again to break them; for you may observe the progressive motions of Cœlestial Bodies with your natural eyes better then through Artificial Glasses. The Bear-men being exceedingly troubled at her Majesties displeasure concerning their Telescopes, kneel'd down, and in the humblest manner petitioned, that they might not be broken; for, said they, we take more delight in Artificial delusions, then in Natural truths. Besides, we shall want Imployments for our Senses, and Subjects for Arguments; for, were there nothing but truth, and no falshood, there would be no occasion to dispute, and by this means we should want the aim and pleasure of our endeavors in confuting and contradicting each other; neither would one man be thought wiser then another, but all would either be alike knowing and wise, or all would be fools; wherefore we most humbly beseech your Imperial Majesty to spare our Glasses, which are our onely delight, and as dear to us as our lives. The Empress at last consented to their request, but upon condition, that their disputes and quarrels should remain within their Schools, and cause no factions or disturbances in State, or Government. The Bear-men, full of joy, returned their most humble thanks to the Empress; and to make her amends for the displeasure which their Telescopes had occasioned, told her Majesty, that they had several other artificial Optick-Glasses, which they were sure would give her Majesty a great deal more satisfaction. Amongst the rest, they brought forth several Microscopes, by the means of which they could enlarge the shapes of little bodies, and make a Lowse appear as big as an Elephant, and a Mite as big as a Whale. First of all they shewed the Empress a gray Drone-flye, wherein they observed that the greatest part of her face, nay, of her head, consisted of two large bunches all cover'd over with a multitude of small Pearls or Hemispheres in a Trigonal order: Which Pearls were of two degrees, smaller and bigger; the smaller degree was lowermost, and looked towards the ground; the other was upward, and looked sideward, forward and backward: They were all so smooth and polished, that they were able to represent the image of any object, the number of them was in all 14000. After the view of this strange and miraculous Creature, and their several observations upon it, the Empress asked them, What they judged those little Hemispheres might be? They answered, That each of them was a perfect Eye, by reason they perceived that each was covered with a Transparent Cornea, containing a liquor within them, which resembled the watery or glassie humor of the Eye. To which the Emperess replied, That they might be glassie Pearls, and yet not Eyes; and that perhaps their Microscopes did not truly inform them. But they smilingly answered her Majesty, That she did not know the vertue of those Microscopes: for they never delude, but rectifie and inform the Senses; nay, the World, said they, would be but blind without them, as it has been in former ages before those Microscopes were invented.

After this, they took a Charcoal, and viewing it with one of their best Microscopes, discovered in it an infinite multitude of pores, some bigger, some less; so close and thick, that they left but very little space betwixt them to be filled with a solid body; and to give her Imperial Majesty a better assurance thereof, they counted in a line of them an inch long, no less then 2700 pores; from which Observation they drew this following Conclusion, to wit, That this multitude of pores was the cause of the blackness of the Coal; for, said they, a body that has so many pores, from each of which no light is reflected, must necessarily look black, since black is nothing else but a privation of light, or a want of reflection. But the Empress replied, That if all Colours were made by reflection of light, and that Black was as much a colour as any other colour; then certainly they contradicted themselves in saying that black was made by want of reflection. However, not to interrupt your Microscopical Inspections, said she, let us see how Vegetables appear through your Glasses; whereupon they took a Nettle, and by the vertue of the Microscope, discovered that underneath the points of the Nettle there were certain little bags or bladders, containing a poysonous liquor, and when the points had made way into the interior parts of the skin, they like Syringe-pipes served to conveigh that same liquor into them. To which Observation the Empress replied, That if there were such poyson in Nettles, then certainly in eating of them, they would hurt us inwardly, as much as they do outwardly? But they answered, That it belonged to Physicians more then to Experimental Philosophers, to give Reasons hereof; for they only made Microscopical inspections, and related the Figures of the Natural parts of Creatures according to the representation of their glasses.

Lastly, They shewed the Empress a Flea, and a Lowse; which Creatures through the Microscope appear'd so terrible to her sight, that they had almost put her into a swoon; the description of all their parts would be very tedious to relate, and therefore I'le forbear it at this present. The Empress, after the view of those strangely-shaped Creatures, pitied much those that are molested with them, especially poor Beggars, which although they have nothing to live on themselves, are yet necessitated to maintain and feed of their own flesh and blood, a company of such terrible Creatures called Lice; who, instead of thanks, do reward them with pains, and torment them for giving them nourishment and food. But after the Empress had seen the shapes of these monstrous Creatures, she desir'd to know, Whether their Microscopes could hinder their biting, or at least shew some means how to avoid them? To which they answered, That such Arts were mechanical and below the noble study of Microscopical observations. Then the Empress asked them, Whether they had not such sorts of Glasses that could enlarge and magnifie the shapes of great Bodies as well as they had done of little ones? Whereupon they took one of their best and largest Microscopes, and endeavoured to view a Whale thorow it; but alas! the shape of the Whale was so big, that its Circumference went beyond the magnifying quality of the Glass; whether the error proceeded from the Glass, or from a wrong position of the Whale against the reflection of light, I cannot certainly tell. The Empress seeing the insufficiency of those Magnifying-Glasses, that they were not able to enlarge all sorts of Objects, asked the Bear-men, whether they could not make Glasses of a contrary nature to those they had shewed her, to wit, such as instead of enlarging or magnifying the shape or figure of an Object, could contract it beneath its natural proportion: Which, in obedience to her Majesties Commands, they did; and viewing through one of the best of them, a huge and mighty Whale appear'd no bigger then a Sprat; nay, through some no bigger then a Vinegar-Eele; and through their ordinary ones, an Elephant seemed no bigger then a Flea; a Camel no bigger then a Lowse; and an Ostrich no bigger then a Mite. To relate all their Optick observations through the several sorts of their Glasses, would be a tedious work, and tire even the most patient Reader, wherefore I'le pass them by; onely this was very remarkable and worthy to be taken notice of, that notwithstanding their great skil, industry and ingenuity in Experimental Philosophy, they could yet by no means contrive such Glasses, by the help of which they could spy out a Vacuum, with all its dimensions, nor Immaterial substances, Non-beings, and Mixt-beings, or such as are between something and nothing; which they were very much troubled at, hoping that yet, in time, by long study and practice, they might perhaps attain to it.

The Bird- and Bear-men being dismissed, the Empress called both the Syrens- or Fish-men, and the Worm-men, to deliver their Observations which they had made, both within the Seas, and the Earth. First, she enquired of the Fish-men whence the saltness of the Sea did proceed? To which they answered, That there was a volatile salt in those parts of the Earth, which as a bosom contain the Waters of the Sea, which Salt being imbibed by the Sea, became fixt; and this imbibing motion was that they call'd the Ebbing and Flowing of the Sea; for, said they, the rising and swelling of the Water, is caused by those parts of the volatile Salt as are not so easily imbibed, which striving to ascend above the Water, bear it up with such a motion, as Man, or some other Animal Creature, in a violent exercise uses to take breath. This they affirmed to be the true cause both of the saltness, and the ebbing and flowing-motion of the Sea, and not the jogging of the Earth, or the secret influence of the Moon, as some others had made the World believe.

After this, the Empress enquired, Whether they had observed, that all Animal Creatures within the Seas and other waters, had blood? They answered, That some had blood, more or less, but some had none. In Crea-fishes and Lobsters, said they, we perceive but little blood; but in Crabs, Oysters, Cockles, &c. none at all. Then the Empress asked them, in what part of their Bodies that little blood did reside? They answered, in a small vein, which in Lobsters went through the middle of their tails, but in Crea-fishes was found in their backs: as for other sorts of Fishes, some, said they, had onely blood about their Gills, and others in some other places of their Bodies; but they had not as yet observed any whose veins did spread all over their Bodies. The Empress wondring that there could be living Animals without Blood, to be better satisfied, desired the Worm-men to inform her, whether they had observed Blood in all sorts of Worms? They answered, That, as much as they could perceive, some had Blood, and some not; a Moth, said they, had no Blood at all, and a Lowse had, but like a Lobster, a little Vein along her back: Also Nits, Snails, and Maggots, as well as those that are generated out of Cheese and Fruits, as those that are produced out of Flesh, had no blood: But, replied the Empress, If those mentioned creatures have no blood, how is it possible they can live? for it is commonly said, That the life of an Animal consists in the blood, which is the seat of the Animal spirits. They answered, That blood was not a necessary propriety to the life of an Animal; and that that which was commonly called Animal spirits, was nothing else but corporeal motions proper to the nature and figure of an Animal. Then she asked both the Fish- and Worm-men, whether all those Creatures that have blood, had a circulation of blood in their veins and arteries? But they answered, That it was impossible to give her Majesty an exact account thereof, by reason the circulation of blood was an interior motion, which their senses, neither of themselves, nor by the help of any Optick Instrument could perceive; but as soon as they had dissected an Animal Creature, to find out the truth thereof, the interior corporeal motions proper to that particular figure or creature, were altered. Then said the Empress, If all Animal Creatures have not blood, it is certain, they all have neither Muscles, tendons, nerves, &c. But, said she, Have you ever observed Animal Creatures that are neither flesh, nor Fish, but of an intermediate degree between both? Truly, answered both the Fish- and Worm-men, We have observed several Animal Creatures that live both in Water, and on the Earth, indifferently, and if any, certainly those may be said to be of such a mixt nature, that is, partly Flesh, and partly Fish: But how is it possible, replied the Empress, that they should live both in Water, and on the Earth, since those Animals that live by the respiration of Air, cannot live within Water; and those that live in Water, cannot live by the respiration of Air, as Experience doth sufficiently witness. They answered her Majesty, That as there were different sorts of Creatures, so they had also different ways of Respirations; for Respiration, said they, is nothing else but a composition and division of parts, and the motions of nature being infinitely various, it is impossible that all Creatures should have the like motions; wherefore it was not necessary, that all Animal Creatures should be bound to live either by the Air, or by Water onely, but according as Nature had ordered it convenient to their Species. The Empress seem'd very well satisfied with their answer, and desired to be further informed, Whether all Animal Creatures did continue their Species by a successive propogation of particulars, and whether in every Species the off-springs did always resemble their Generator or Producer, both in their interior and exterior Figures? They answered, her Majesty, That some Species or sorts of Creatures, were kept up by a successive propagation of an off-spring that was like the producer, but some were not. Of the first rank, said they, are all those Animals that are of different sexes, besides several others; but of the second rank are for the most part those we call Insects, whose production proceds from such causes as have no conformity or likeness with their produced Effects; as for example, Maggots bred out of Cheese, and several others generated out of Earth, Water, and the like. But said the Empress, there is some likeness between Maggots and Cheese; for Cheese has no blood, nor Maggots neither; besides, they have almost the same taste which Cheese has. This proves nothing, answered they; for Maggots have a visible, local, progressive motion, which Cheese hath not. The Empress replied, That when all the Cheese was turned into Maggots, it might be said to have local, progressive motion. They answered, That when the Cheese by its own figurative motions was changed into Maggots, it was no more Cheese. The Empress confessed that she observed Nature was infinitely various in her works, and that though the species of Creatures did continue, yet their particulars were subject to infinite changes. But since you have informed me, said she, of the various sorts and productions of Animal Creatures, I desire you to tell me what you have observed of their sensitive perceptions? Truly, answered they, Your Majesty puts a very hard question to us, and we shall hardly be able to give a satisfactory answer to it; for there are many different sorts of Creatures, which as they have all different perceptions, so they have also different organs, which our senses are not able to discover, onely in an Oystershell we have with admiration observed, that the common sensorium of the Oyster lies just as the closing of the shells, where the pressure and re-action may be perceived by the opening and shutting of the shells every tide.

After all this, the Empress desired the Worm men to give her a true Relation how frost was made upon the Earth? To which they answered, That it was made much after the manner and description of the Fish- and Bird-men, concerning the Congelation of Water into Ice and Snow, by a commixture of saline and acid particles; which relation added a great light to the Ape-men, who were the Chymists, concerning their Chymical principles, Salt, Sulphur, and Mercury. But, said the Empress, if it be so, it will require an infinite multitude of saline particles to produce such a great quantity of Ice, Frost and Snow: besides, said she, when Snow, Ice and Frost, turn again into their former principle, I would fain know what becomes of those saline particles? But neither the Worm-men, nor the Fish- and Bird-men, could give her an answer to it.

Then the Empress enquired of them the reason, Why Springs were not as salt as the Sea is? also, why some did ebb and flow? To which it was answered, That the ebbing and flowing of some Springs, was caused by hollow Caverns within the Earth, where the Seawater crowding thorow, did thrust forward, and drew backward the Spring-water, according to its own way of ebbing and flowing; but others said, That it proceeded from a small proportion of saline and acid particles, which the Spring-water imbibed from the Earth; and although it was not so much as to be perceived by the sense of Taste; yet it was enough to cause an ebbing and flowing-motion. And as for the Spring- water being fresh, they gave, according to their Observation, this following reason: There is, said they, a certain heat within the Bowels of the Earth, proceeding from its swift circular motion, upon its own axe, which heat distills the rarest parts of the Earth into a fresh and insipid water, which water being through the pores of the Earth, conveighed into a place where it may break forth without resistance or obstruction, causes Springs and Fountains; and these distilled Waters within the Earth, do nourish and refresh the grosser and drier parts thereof. This Relation confirmed the Empress in the opinion concerning the motion of the Earth, and the fixedness of the Sun, as the Bird-men had informed her; and then she asked the Worm-men, whether Minerals and Vegetables were generated by the same heat that is within the Bowels of the Earth? To which they could give her no positive answer; onely this they affirmed, That heat and cold were not the primary producing causes of either Vegetables or Minerals, or other sorts of Creatures, but onely effects; and to prove this our assertion, said they, we have observed, that by change of some sorts of Corporeal motions, that which is now hot, will become cold; and what is now cold, will grow hot; but the hottest place of all, we find to be the Center of the Earth: Neither do we observe, that the Torrid Zone does contain so much Gold and Silver as the Temperate; nor is there great store of Iron and Lead wheresoever there is Gold; for these Metals are most found in colder Climates towards either of the Poles. This Observation, the Empress commanded them to confer with her Chymists, the Ape-men; to let them know that Gold was not produced by a violent, but a temperate degree of heat. She asked further, Whether Gold could not be made by Art? They answered, That they could not certainly tell her Majesty, but if it was possible to be done, they thought Tin, Lead, Brass, Iron and Silver, to be the fittest Metals for such an Artificial Transmutation. Then she asked them, Whether Art could produce Iron, Tin, Lead, or Silver? They answered, Not, in their opinion. Then I perceive, replyed the Empress, that your judgments are very irregular, since you believe that Gold, which is so fixt a Metal, that nothing has been found as yet which could occasion a dissolution of its interior figure, may be made by Art, and not Tin, Lead, Iron, Copper or Silver, which yet are so far weaker, and meaner Metals then Gold is. But the Worm-men excused themselves, that they were ignorant in that Art, and that such questions belonged more properly to the Ape-men, which were Her Majesties Chymists.
