I could instance also in the Figure of _Sea-salt_, and _Sal-gem_, that it is compos'd of a texture of _Globules_, placed in a _cubical_ form, as L, and that all the Figures of those Salts may be imitated by this texture of _Globules_ and by no other whatsoever. And that the forms of _Vitriol_ and of _Salt-Peter_, as also of _Crystal_, _Hore-frost_, &c. are compounded of these two textures, but modulated by certain proprieties: But I have not here time to insist upon, as I have not neither to shew by what means _Globules_ come to be thus context, and what those _Globules_ are, and many other particulars requisite to a full and intelligible explication of this propriety of bodies. Nor have I hitherto found indeed an opportunity of prosecuting the inquiry so farr as I design'd; nor do I know when I may, it requiring abundance of time, and a great deal of assistance to go through with what I design'd; the model of which was this: First, to get as exact and full a collection as I could, of all the differing kinds of Geometrical figur'd bodies, some three or four several bodies of each kind. Secondly, with them to get as exact a History as possibly I could learn of their places of Generation or finding, and to enquire after as many circumstances that tended to the Illustrating of this Enquiry, as possibly I could observe. Thirdly, to make as many trials as upon experience I could find requisite, in Dissolutions and Coagulations of several crystallizing Salts; for the needfull instruction and information in this Enquiry. Fourthly, to make several trials on divers other bodies, as Metals, Minerals, and Stones, by dissolving them in several _Menstruums_, and |
