I know it may be said, that Chymists in the Opinion above recited mean the Principle of Sulphur, and not common Sulphur which receives its name, not from its being all perfectly of a Sulphureous Nature, but for that plenty and Predominancy of the Sulphureous Principle in it.
The European chymists have since reasoned upon fermentation; each of them has produced a new system; none have been able to bring it to a regular demonstration; and the learned Gay Lussac has said, that fermentation is one of the most mysterious operations of chymistry.
These need not detain us, since the important aspect of Needham's work relevant to our purpose is his continuation of the chemical analysis of the developing embryo and its demonstration that, although Harvey might have despised the "chymists" and been contemptuous of the "mechanical, corpuscular philosophy," this system and approach was not to be denied.
A part of the tube that conducts the inflammable air, carries off, out of doors, the produce of this combustion, which, nevertheless, according to the experiments of modern chymists, can scarcely be any thing more than an aqueous vapour. "Who cannot but be fond of having recourse to a flame so subservient?
He requested the Committee to cause them to be examined, asked for orders on this subject, and wished to set off again immediately. The most skilful chymists were instantly assembled: they were ordered to analyze the brandies, and to indicate, in the course of the day, the poison and the remedy. These savans laboured without intermission, trusting only to themselves for the most minute details.
Now they would see how that Love in her curious Crusible, melteth two hearts and ten sences together. To this all Chymists vail their Bonnets, though they brag of their making the hardest Minerals as soft as Milk and Butter. This Art surpasseth all others. Yet here ought to be considered what sort of Trading shall be pitcht upon.
Nor is the Turbith Mineral, that Chymists extol for its power to Salivate, and for other vertues, of a Colour much inferiour to this, though it be often made with a differing proportion of the Ingredients, a more troublesome way.
Wherefore I shall now make only this Observation from what has been deliver'd, That in these Operations there appears not any cause to attribute the new Colours emergent to the Action of a new Substantial form, nor to any Increase or Decrement of either the Salt, Sulphur, or Mercury of the Matter that acquires new Colours: For the Vessels are clos'd, and these Principles according to the Chymists are Ingenerable and Incorruptible; so that the Effect seems to proceed from hence, that the Heat agitating and shuffling the Corpuscles of the Body expos'd to it, does in process of time so change its Texture, as that the Transposed parts do Modifie the incident Light otherwise, than they did when the Matter appear'd of another Colour.
You must know, that about the fall of the Evening, and at that time when the aequilibrium of Day and Night, for some time, holds the Air in a gloomy suspence between an unwillingness to leave the light, and a natural impulse into the Dominion of darkness, about this time our Hero's, shall I say, sally'd or slunk out of their Lodgings, and steer'd toward the great Palace, whither, before they were arrived, such a prodigious number of Torches were on fire, that the day, by help of these Auxiliary Forces, seem'd to continue its Dominion; the Owls and Bats apprehending their mistake, in counting the hours, retir'd again to a convenient darkness; for Madam Night was no more to be seen than she was to be heard; and the Chymists were of Opinion, That her fuliginous Damps, rarefy'd by the abundance of Flame, were evaporated.
And in this transaction before the Committee, one Cocket an Apothecary exhibited in the name of the Chymists such a Scandalous Libel, as the Committee would not suffer to be read; drawn as some conceive by the assistance, and countenance, if not contrivance of his Company.
