FOOTNOTES:
[a] The most eminent Author I have met with, that finds fault with the Distribution of the Earth and Waters, and indeed with the whole present Structure of the Globe, is the learned and eloquent Theorist, Dr. Burnet, who frequently exclaims on this Point, Tellus nostra, si totam simul complectamur, non est ordinata & venusta rerum compages——sed moles aggesta vario, incertoque situ partium, nullâ ordinis aut venustatis habitâ ratione. Theor. Sacr. l. 1. c. 7. Ecquis autem à Deo hæc ita facta? &c. ib. Quo autem Herculeo labore opus effet ad excavandum terram in tantum hiatum?——Si immediatè à causâ primâ effectus fuisset hic alveus, aliquem saltem ordinem, mensuram, & proportionem notare voluisset in ipsius formâ, & partium dispositione;——sed confusa omnia, &c. ib. c. 8. Tellus nostra cùm exigua sit, est etiam rudis: Et in illâ exiguitate multa sunt superflua, multa inelegantia. Dimidiam terræ superficiem inundat Oceanus; magnâ ex parte, ut mihi videtur, inutilis. And then he goes on to shew how this Part of the Creation might be mended, ib. c. 10. All this is to me surprizing from an Author of great Ingenuity, who seems in his Book to have a just Opinion of, and due Veneration for God. But certainly such Notions are very inconsistent with the Belief of God’s creating, especially his governing and ordering the World. But suppose the Terraqueous Globe was such a rude, confused, inconvenient Mass, as he pretends, yet it is well enough for a sinful World. But besides, what others have long ago abundantly answered, the following Survey, will, I hope, sufficiently manifest it to be the Work of a wise and beneficent, as well as omnipotent Creator.
[] Some have objected against the Distribution of the Earth and Waters, as if the Waters occupied too large a part of the Globe, which they think would be of greater Use, if it was dry Land. But then they do not consider that this would deprive the World of a due Quantity of Vapours and Rain. For if the Cavities which contain the Sea, and other Waters, were deeper, although the Waters were no less in Quantity, only their Surfaces narrower and lesser, the Evaporations would be so much the less, inasmuch as those Evaporations are made from the Surface, and are, consequently, in proportion to the Surface, not the Depth or Quantity of Water.
[c] I took notice before in [Book I. Chap. 3. Note (a).] That the Vapours constituting Clouds and Rain, are Vesiculæ of Water detached by Heat. The manner of which I conceive to be thus; Heat being of an agile Nature, or the lightest of all Bodies, easily breaks loose from them; and if they are humid, in its Passage, carries along with it Particles, or little Cases of the Water; which being lighter than Air, are buoyed up thereby, and swim in it; until by knocking against one another, or being thickened by the Cold, (as in the Note before-cited,) they are reduced into Clouds and Drops.
Having mentioned the manner how Vapours are raised, and there being more room here than in the Note before-cited, I shall, for the Illustration of Natures Process, take notice of three Things observable to our purpose, in Water over the Fire. 1. That the Evaporations are proportional to the Heat ascending out of the Water. A small Heat throws off but few Vapours, scarce visible: A greater Heat, and ascending in greater Quantities, carries off grosser, larger, and more numerous Vesiculæ, which we call a Steam: And if the Heat breaks through the Water with such a Fury, as to lacerate and lift up great Quantities or Bubbles of Water, too heavy for the Air to carry or buoy up, it causeth what we call Boyling. And the Particles of Water thus mounted up by the Heat, are visible Sphærules of Water, if viewed with a Microscope, as they swim about in a Ray of the Sun let into a dark Room, with warm Water underneath; where some of the Vapours appear large, some smaller Sphærules, according (no doubt) to the larger and lesser Quantities of Heat blowing them up and carrying them off. 2. If these Vapours be intercepted in their Ascent by any Context, especially cold Body, as Glass, Marble, &c. they are thereby reduced into Drops, and Masses of Water, like those of Rain, &c. 3. These Vapours in their Ascent from the Water, may be observed, in cold frosty Weather, either to rise but a little above the Water, and there to hang, or to glide on a little above its Surface: Or if the Weather be very cold, after a little ascent, they may be seen to fall back again into the Water; in their Ascent and Descent describing a Curve somewhat like that of an Arrow from a Bow. But in a warmer Air, and still, the Vapours ascend more nimbly and copiously, mounting up aloft, till they are out of Sight. But if the Air be warm and windy too, the Vapours are sooner carried out of Sight, and make way for others. And accordingly I have often observed, that hot Liquors, if not set too thin, and not frequently stirred, cool slower in the greatest Frosts, than in temperate Weather, especially if windy. And it is manifest by good Experiments, that the Evaporations are less at those times than these; less by far in the Winter than the warmer Months.
[c] As our Northern Islands are observed to be more temperate than our Continents, (of which we had a notable Instance in the great Frost in 1708/9, which Ireland and Scotland felt less of, than most Parts of Europe besides; of which see [Book IV. Chap. 12. Note (c).]) so this Temperature is owing to the warm Vapours afforded chiefly by the Sea, which by [the preceding Note] must necessarily be warm, as they are Vapours, or Water inflated by Heat.
The Cause of this Heat I take to be partly that of the Sun, and partly Subterraneous. That it is not wholly that of the Sun, is manifest from Vapours, being as, or more copiously raised when the Sun Beams are weakest, as when strongest, there being greater Rains and Winds at the one time than the other. And that there is such a thing as Subterraneous Heat, (whether Central, or from the meeting of Mineral Juices; or such as is Congenial or Connatural to our Globe, I have not Time to enquire; but I say, that such a Thing is,) is evident not only from the Hot-Baths, many fiery Erruptions and Explosions, &c. but also from the ordinary Warmth of Cellars and Places under Ground, which are not barely comparatively warm, but of sufficient Heat to raise Vapours also: As is manifest from the smoking of perennial Fountains in frosty Weather, and Water drawn out of Pumps and open Wells at such a Time. Yea, even Animals themselves are sensible of it, as particularly Moles, who dig before a Thaw, and against some other Alterations of the Weather; excited, no doubt, thereunto by the same warm Vapours arising in the Earth, which animate them, as well as produce the succeeding Changes of the Weather.
[d] Besides the Trade-Winds, which serve to mitigate the excessive Heats in the Torrid Zone; the Clouds are a good Screen against the scorching Sun-Beams, especially when the Sun passeth their Zenith; at which Time is their Winter, or coolest Season, by reason they have then most Clouds and Rain. For which Service, that which Varene takes notice of, is a great Providence of God, viz. Pleraque loca Zonæ Torridæ vicinum habent mare, ut India, Insulæ Indicæ, Lingua Africæ, Guinea, Brasilia, Peruvia, Mexicana, Hispania: Pauca loca Zonæ Torridæ sunt Mediterranea. Varenii. Geogr. l. 2. c. 26. Prop. 10. §. 7.
[e] That Springs have their Origine from the Sea, and not from Rains and Vapours, among many other strong Reasons, I conclude from the Perennity of divers Springs, which always afford the same quantity of Water. Of this sort there are many to be found every where. But I shall, for an Instance, single out one in the Parish of Upminster, where I live, as being very proper for my purpose, and one that I have had better Opportunities of making Remarks upon above twenty Years. This in the greatest Droughts is little, if at all diminished, that I could perceive by my Eye, although the Ponds all over the Country, and an adjoining Brook have been dry for many Months together; as particularly in the dry Summer Months of the Year 1705. And in the wettest Seasons, such as the Summer and other Months were, preceding the violent Storm in November 1703. (Vid. Philos. Trans. Nᵒ. 289.) I say, in such wet Seasons I have not observed any Increment of its Stream, excepting only for violent Rains falling therein, or running down from the higher Land into it; which discoloureth the Waters oftentimes, and makes an increase of only a Day’s, or sometimes but a few Hours Continuance. But now, if this Spring had its Origine from Rain and Vapours, there would be an increase and decrease of the one, as there should happen to be of the other: As actually it is in such temporary Springs as have undoubtedly their Source from Rain and Vapours.
But besides this, another considerable Thing in this Upminster Spring (and Thousands of others) is, that it breaks out of so inconsiderable an Hillock, or Eminence of Ground, that can have no more Influence in the Condensation of the Vapours, or stopping the Clouds, (which the Maintainers of this Hypothesis suppose) than the lower Lands about it have. By some Critical Observations I made with a very nice portable Barometer, I found that my House stands between 80 and 90 Feet higher than the Low-Water Mark in the River of Thames, nearest me; and that part of the River being scarce thirty Miles from the Sea, I guess, (and am more confirmed from some later Experiments I made nearer the Sea) that we cannot be much above 100 Feet above the Sea. The Spring I judge nearly level with, or but little higher than where my House stands; and the Lands from whence it immediately issues, I guess about 15 or 20 Feet higher than the Spring: and the Lands above that, of no very remarkable Height. And indeed, by actual Measure, one of the highest Hills I have met with in Essex, is but 363 Feet high; (Vid. Phil. Trans. Nᵒ. 313. p. 16.) and I guess by some very late Experiments I made, neither that, nor any other Land in Essex, to be above 400 Feet above the Sea. Now what is so inconsiderable a rise of Land to a perennial Condensation of Vapours, fit to maintain even so inconsiderable a Fountain, as what I have mentioned is? Or indeed the High-lands of the whole large County of Essex, to the maintaining of all its Fountains and Rivulets?
But I shall no farther prosecute this Argument, but refer to the late learned, curious and industrious Dr. Plot’s Tentamen Phil. de Orig. Font. in which he hath fully discussed this Matter.
As to the manner how the Waters are raised up into the Mountains and Higher Lands, an easy and natural Representation may be made of it, by putting a little Heap of Sand, Ashes, or a little Loaf of Bread, &c. in a Bason of Water; where the Sand will represent the dry Land, or an Island, and the Bason of Water the Sea about it. And as the Water in the Bason riseth to, or near the top of the Heap in it, so doth the Waters of the Sea, Lakes, &c. rise in the Hills. Which case I take to be the same with the ascent of Liquids in capillary Tubes, or between contiguous Planes, or in a Tube filled with Ashes: Of which the industrious and compleat Artificer in Air-Pumps, Mr. Hawksbee, hath given us some, not contemptible Experiments, in his Phys. Mech. Exp. pag. 139.
Among the many Causes assigned for this ascent of Liquors, there are two that bid the fairest for it, viz. the Pressure of the Atmosphere, and the Newtonian Attraction. That it is not the former, appears from the Experiments succeeding, as well, or better in Vacuo, than in the open Air, the ascent being rather swifter in Vacuo. This then being not the Cause, I shall suppose the other is; but for the Proof thereof, I shall refer to some of our late English Authors, especially some very late Experiments made before our most famous R. S. which will be so well improved by some of that illustrious Body, as to go near to put the Matter out of doubt.

CHAP. VI.
The great Variety and Quantity of all Things upon, and in the Terraqueous Globe, provided for the Uses of the World.
The last Remark I shall make about the Terraqueous Globe in general is, the great Variety of Kinds, or Tribes, as well as prodigious Number of Individuals of each various Tribe, there is of all Creatures[a]. There are so many Beasts, so many Birds, so many Insects, so many Reptiles, so many Trees, so many Plants upon the Land; so many Fishes, Sea-Plants, and other Creatures in the Waters; so many Minerals, Metals, and Fossiles in the Subterraneous Regions; so many Species of these Genera, so many Individuals of those Species, that there is nothing wanting to the Use of Man, or any other Creature of this lower World. If every Age doth change its Food, its way of Cloathing, its way of Building; if every Age[] hath its Variety of Diseases; nay, if Man, or any other Animal, was minded to change these Things every Day, still the Creation would not be exhausted, still nothing would be wanting for Food, nothing for Physick, nothing for Building and Habitation, nothing for Cleanliness and Refreshment, yea, even for Recreation and Pleasure. But the Munificence of the Creator is such, that there is abundantly enough to supply the Wants, the Conveniencies, yea, almost the Extravagancies of all the Creatures, in all Places, all Ages, and upon all Occasions.
And this may serve to answer an Objection against the Excellency of, and Wisdom shewed in the Creation; namely, What need of so many Creatures[c]? Particularly of so many Insects, so many Plants, and so many other Things? And especially of some of them, that are so far from being useful, that they are very noxious; some by their Ferity, and others by their poisonous Nature, &c.?
To which I might answer, that in greater Variety, the greater Art is seen; that the fierce, poisonous, and noxious Creatures serve as Rods and Scourges to chastise us[d], as means to excite our Wisdom, Care, and Industry, with more to the same purpose. But these Things have been fully urged by others; and it is sufficient to say, that this great Variety is a most wise Provision for all the Uses of the World in all Ages and all Places. Some for Food, some for Physick[e], some for Habitation, some for Utensils, some for Tools and Instruments of Work, and some for Recreation and Pleasure, either to Man, or to some of the inferior Creatures themselves; even for which inferior Creatures, the liberal Creator hath provided all Things necessary, or any ways conducing to their happy, comfortable living in this World, as well as for Man.
And it is manifest, that all the Creatures of God, Beasts, Birds, Insects, Plants, and every other Genus have, or may have, their several Uses even among Men. For although in one Place many Things may lie neglected, and out of Use, yet in other Places they may be of great Use. So what hath seemed useless in one Age, hath been received in another; as all the new Discoveries in Physick, and all the Alterations in Diet do sufficiently witness. Many Things also there are which in one Form may be pernicious to Man; but in another, of great Use. There are many Plants[f], many Animals, many Minerals, which in one Form destroy, in another heal. The Cassada Plant unprepared poisoneth, but prepared, is the very Bread of the West-Indies[g]. Vipers and Scorpions, and many Minerals, as destructive as they are to Man, yet afford him some of his best Medicines.
Or if there be many Things of little, immediate Use to Man, in this, or any other Age; yet to other Creatures they may afford Food or Physick, or be of some necessary Use. How many Trees and Plants, nay, even the very Carcases of Animals, yea, the very Dust of the Earth[h], and the most refuse, contemptible Things to be met with; I say, how many such Things are either Food, or probably Medicine to many Creatures, afford them Retreat, are Places of Habitation, or Matrixes for their Generation, as shall be shewed in proper Place? The prodigious Swarms of Insects in the Air, and in the Waters, (many of which may be perhaps at present of no great Use to Man) yet are Food to Birds, Fishes, Reptiles, Insects themselves, and other Creatures[], for whose happy and comfortable Subsistence, I have said the bountiful Creator hath liberally provided, as well as for that of Man.
