The second and most common ground is from the name _Crystallus_, whereby in Greek both Ice and Crystal are expressed; which many not duly considering, have from their community of name, conceived a community of nature; and what was ascribed unto the one, not unfitly appliable unto the other. But this is a fallacy of Æquivocation, from a society in name inferring an Identity in nature. By this fallacy was he deceived that drank _Aqua fortis_ for strong water. By this are they deluded, who conceive _sperma Cœti_ which is found about the head, to be the spawn of the Whale: Or take _sanguis draconis_ (which is the gumme of a tree,) to be the blood of a Dragon. By the same Logick we may infer, the Crystalline humour of the eye, or rather the Crystalline heaven above, to be of the substance of Crystal here below; Or that God sendeth down Crystal, because it is delivered in the vulgar translation, Psal. 47. _Mittit Crystallum suum sicut Buccellas_. [SN: _Agreement in name._] Which translation although it literally express the Septuagint; yet is there no more meant thereby, than what our translation in plain English expresseth; that is, he casteth forth his Ice like morsels, or what _Tremellius_ and _Junius_ as clearly deliver, _Deficit gelu suum sicut frusta, coram frigore ejus quis consistet?_ which proper and latine expressions, had they been observed in ancient translations, elder Expositors had not been misguided by the Synonomy; nor had they afforded occasion unto _Austin_, the Gloss, _Lyranus_, and many others, to have taken up the common conceit, and spoke of this Text conformably unto the opinion rejected. CHAPTER II Concerning the Loadstone. Of things particularly spoken thereof, evidently or probably true. Of things generally believed, or particularly delivered, manifestly or probably false. In the first of the Magnetical vertue of the Earth, of the four motions of the stone, that is, its Verticity or Direction, its Attraction or Coition, its Declination, its Variation, and also of its Antiquity. In the second a rejection of sundry opinions and relations thereof, Natural, Medical, Historical, Magical. [Sidenote: _How the earth is a Magnetical body._]
