fundamental Atomes thereof; which seems to be some feathery particle of Snow; although Snow it self be sexangular, or at least of a starry and many-pointed figure. They are also differenced in the places of their generation; for though Crystal be found in cold countries, and where Ice remaineth long, and the air exceedeth in cold, yet is it also found in regions, where Ice is seldom seen or soon dissolved; as _Pliny_ and _Agricola_ relate of _Cyprus_, _Caramania_ and an Island in the Red sea; It hath been also found in the veins of Minerals, sometimes agglutinated unto lead, sometimes in Rocks, opacous stones, and the marble face of _Octavius_ Duke of _Parma_. [SN: _Wherein the Sculptor found a piece of pure Crystal._] It hath also constant veins; as beside others, that of mount _Salvino_ about the Territory of _Bergamo_; from whence if part be taken, in no long tract of time out of the same place, as from its mineral matrix, others are observed to arise. Which made the learned _Cerautus_ to conclude, _Videant hi an sit glacies, an vero corpus fossile_. [SN: _Mus. Calceolar._] It is also found in the veins of Minerals, in rocks, and sometime in common earth. But as for Ice, it will not readily concrete but in the approachment of the air, as we have made trial in glasses of water, covered an inch with oyl, which will not easily freeze in hard frosts of our climate. For water commonly concreteth first in its surface, and so conglaciates downward; and so will it do although it be exposed in the coldest metal of lead, which well accordeth with that expression of _Job_, _The waters are hid as with a stone, and the face of the deep is frozen_. [SN: _Chap. 38._] But whether water which hath been boiled or heated, doth sooner receive this congelation, as commonly is delivered, we rest in the experiment of _Cabeus_, who hath rejected the same in his excellent discourse of Meteors. They have contrary qualities elemental, and uses medicinal; for Ice is cold and moist, of the quality of water; but Crystal is cold and dry, according to the condition of earth. The use of Ice is condemned by most Physicians, that of Crystal commended by many. For although _Dioscorides_ and _Galen_ have left no mention thereof, yet hath _Mathiolus_, _Agricola_, and many commended it in dysenteries and fluxes; all for the increase of milk, most Chymists for the Stone, and some, as _Brassavolus_ and _Bœtius_, as an antidote against poyson. Which occult and specifical operations are not expectable from Ice; for being but water congealed, it can never make good such qualities; nor will it reasonably admit of secret proprieties, which are the affections of forms, and compositions at distance from their elements.
