I have elsewhere endeavor'd to show, that divers if not most are the real vertues of some gems, for there are too many fabulous ones ascrib'd to them, proceed from the particles of mineral juices <that were admitted [ 'into as' deleted] whilst the matter> was yet in [ 'ei' deleted] solutis principiis or at least soft, and afterwards coagulated with the Lapidiscent part of the [ 'Sin' deleted] stone. In confirmation of this conjecture we shall now observe, that having upon some grounds not necessary to be here mention'd, suspected that [ 'in' deleted] Granates contain som of them besides som [ 'of' deleted] other metalline substances, divers corpuscles of a martial nature, I [ 'chose' deleted] made choice of some small ones, which by their deep & almost dark colour, (to name [ '[approximately 1 character illegible]' deleted] no other signs) I guess'd to contain somwhat of <Iron or>[replacing 'If'] Steel [ 'or Iron' deleted] and applyd to them a pretty vigorous Loadstone, which as I expected['ex' inserted, replacing 're' deleted], readily took them up, & to which they constantly stuck afterwards til I forcibly separated them from it. But['B' altered from 'T'] thô I try'd this upon more parcels of Garnets than one or two, yet I found that there was not many in['i' altered from 'o'] one heap that would easily adhere to the Magnet.
