Suppose that I have need of some pounds of spirit of salt, and want the opportunity of preparing it in a long time, by the force of fire, I use the following preparation. Instead of a great and continual fire, I use a separatory Art, severing the pure from the impure, dissolving common Kitchin-salt, or salt-petre, in common Water, and adding to the solution put into a Cucurbit a separatory sulphur. The Cucurbit, with a Head or Retort, (by which also the Destillation may be made) being set in sand, I kindle a fire, by which the water containing the salt may boil, and so by the sulphur, in the boiling, the pure parts are separated from the impure; the purer parts are rendered very fugacious and sweet clear spirits; the grosser, more earthy and fixed salt remaineth in the Cucurbit or Retort, of a very wonderful Nature and Property. And after this manner, from one pound of salt or salt-petre, may easily be destilled one pound of spirit of salt, or spirit of Nitre. From a pretty large Cucurbit, in ten hours, may be made ten pounds of spirit of salt, or spirit of Nitre, which two spirits being mixed together, make an Aqua-regia. The quantity of your spirit in each Destillation will be greater or lesser, according as your Cucurbit is larger or smaller. He that desireth to make Aqua-regia by the same destillation, must dissolve equal parts of salt and salt-petre in Water, and destil by a Body or Retort.
This is indeed an excellent Compendium for all those that need a great quantity of those Spirits. Gold, Silver, as also all the other Metals, may be dissolved without Aqua-fortis, or Aqua-regis, and the like spirits, by the help of certain salts dissolved in water, which truly is also a famous Invention. So also it is with those other rare Experiments above mentioned; as for example, If a metal ought to grow in height, something contrary is to be added to it; for this, while it flieth from its contrary, arising out of the mass, groweth up as well in the dry as the moist way.
If we would have an hard Metal or Flint bring forth an Herb; the Metal, whether it be gold, silver, copper, iron, tin, or lead, are first to be reduced into a tender Powder by salts, and that Powder being put into an Earthen Vessel, is to be moistened with a certain peculiar Water, and the seeds of the Herbs to be sowed or set therein, which after they are grown to perfection, are to be no longer moistened, but the powder is to be exposed to the Rays of the Sun, which again becoming a metal or an hard stone, plainly like to another metal or stone, containeth the inhering Roots of the Herb, and causeth the Ignorant to admire how an Herb should grow out of a piece of Gold, Silver, Iron, Copper, or an hard Flint. This is also certain, and not to be doubted, that the said Herbs so growing out of the Metals, do obtain the nature and properties of those out of which they arise.
Although these Experiments of Herbs thus growing afford no profit, yet they are noble Operations of Nature and Art, having more in them than they promise at the first sight, therefore I have not here brought them in vain, inasmuch as they are of no small moment.
But that I may here (at least) mention somewhat of this growing faculty of Vegetables and Metals, be it known to every one, that in my publick Laboratory shall be seen the seeds of all sorts of Herbs, and especially of Grain, as Wheat, Barly, Oats, and others, viz. by what means they may be so prepared, as to acquire a swift faculty of growing, and that one grain may produce ten, twenty, or thirty strong stalks, with full ears, and fruit an hundred fold.
In like manner shall be shewed to some Friends, how Salt-Petre, as the only promoter and helper of the growing faculty, may be sowed it self, so that it shall recompence the labour an hundred fold; for salt-petre multiplieth it self, and groweth up out of common salt, like other Vegetables; whence that old Proverb of sowing of salt might perhaps take its Original.
It behoveth that I here make mention of yet another wonderful thing concerning the growing faculty, to be shewn (God willing) in my private Laboratory. And it is this, that Gold and Silver do grow, are encreased and multiplied out of gross Saturn, even as the seeds of Vegetables, out of a dunged and salt Earth, so that in fifty ounces there is daily an augmentation of one ounce, if not of two. He that shall be here a good Husbandman, and skilful in ploughing of Saturn, and rendering him fertile, and of sowing or planting in him a fit seed, he will have a plentiful Harvest, answerable to the seed which he sowed, and will easily gain three or four times as much.
Therefore, because the growing faculty of Vegetables, Animals, and Minerals, or Metals, taketh its rise from the only and Universal Salt of the Earth, and this from the Salt of the Sea, and the Sea Salt, from the Sun, if the Divine Goodness shall grant me Life, I will shew to my Friends, how by small labour and charge, the Universal Salt fatness, fit for the rendring all barren and sandy ground fruitful, instead of Dung, may be copiously separated from Sea Salt. Yea if need require, I can easily demonstrate, that also the natural Seed of Gold, the true Universal Medicine may be prepared of the same, or that it may be acquired from the visible Ocean which is known to every Man. But seeing that belongs not to this place, we referr the Reader, desirous of such subtile knowledge, to the Treatise of the Nature of Salts, where he will find those things which will satisfie his desire.
These, and the like Experiments shall be shewn in my Laboratory, among all which, that is the most excellent, by which a Man, without the incommoding of another, and with great quietness and Tranquility, may honestly get his Food and Raiment. There shall be also demonstrated those four Arcanums treated of in the Continuation of Miraculum Mundi, and many other things treated of in my Writings, which many believe cannot be effected. That so I, by giving an occular Demonstration, may vindicate my Writings from the Injuries and Reproaches of the ignorant, and also leave behind me somewhat for the good of Posterity.
