But, sayes _Carneades_, if you remember that 'tis a Sceptick speaks to you, and that 'tis not so much my present Talk to make assertions as to suggest doubts, I hope you will look upon what I have propos'd, rather as a Narrative of my former conjectures touching the principles of things, then as a Resolute Declaration of my present opinions of them; especially since although they cannot but appear Very much to their Disadvantage, If you Consider Them as they are propos'd without those Reasons and Explanations by which I could perhaps make them appear much lesse extravagant; yet I want time to offer you what may be alledg'd to clear and countenance these notions; my design in mentioning them unto you at present being, _partly_, to bring some Light and Confirmation to divers passages of my discourse to you; _partly_ to shew you, that I do not (as you seem to have suspected) embrace all _Epicurus_ his principles; but Dissent from him in some main things, as well as from _Aristotle_ and the Chymists, in others; & _partly_ also, or rather chiefly, to intimate to you the grounds upon which I likewise differ from _Helmont_ in this, that whereas he ascribes almost all things, and even diseases themselves, to their determinate Seeds; I am of opinion, that besides the peculiar Fabricks of the Bodies of Plants and Animals (and perhaps also of some Metals and Minerals) which I take to be the Effects of seminal principles, there are many other bodies in nature which have and deserve distinct and Proper names, but yet do but result from such contextures of the matter they are made of, as may without determinate seeds be effected by heat, cold, artificial mixtures and compositions, and divers other causes which sometimes nature imployes of her own accord; and oftentimes man by his power and skill makes use of to fashion the matter according to his Intentions. This may be exemplified both in the productions of Nature, and in those of Art; of the first sort I might name multitudes; but to shew how sleight a variation of Textures without addition of new ingredients may procure a parcel of matter divers names, and make it be Lookt upon as Different Things; I shall invite you to observe with me, That Clouds, Rain, Hail, Snow, Froth, and Ice, may be but water, having its parts varyed as to their size and distance in respect of each other, and as to motion and rest. And among Artificial Productions we may take notice (to skip the Crystals of Tartar) of Glass, Regulus, Martis-Stellatus [Errata: Regulus Martis Stellatus], and particularly of the Sugar of Lead, which though made of that insipid Metal and sour salt of Vinager, has in it a sweetnesse surpassing that of common Sugar, and divers other qualities, which being not to be found in either of its two ingredients, must be confess'd to belong to the Concrete it self, upon the account of its Texture.
