In the same form may we place _Fracastorius_ his attraction of silver. _Philostratus_ his _Pantarbes_, _Apollodorus_ and _Beda_ his relation of the Loadstone that attracted onely in the night. But most inexcusable is _Franciscus Rueus_, a man of our own profession; who in his discourse of _Gemms_ mentioned in the _Apocalyps_, undertakes a Chapter of the Loadstone. Wherein substantially and upon experiment he scarce delivereth any thing: making long enumeration of its traditional qualities, whereof he seemeth to believe many, and some above convicted by experience, he is fain to salve as impostures of the Devil. But _Bœtius de Boot_ Physitian unto _Rodulphus_ the second, hath recompenced this defect; and in his Tract _De Lapidibus & Gemmis_, speaks very materially hereof; and his Discourse is consonant unto Experience and Reason. As for Relations Historical, though many there be of less account, yet two alone deserve consideration: The first concerneth magnetical Rocks, and attractive Mountains in several parts of the Earth. The other the Tomb of _Mahomet_ and bodies suspended in the air. Of Rocks magnetical there are likewise two relations; for some are delivered to be in the _Indies_, and some in the extremity of the North, and about the very Pole. The Northern account is commonly ascribed unto _Olaus Magnus_ Archbishop of _Upsale_, who out of his Predecessor _Joannes_, _Saxo_, and others, compiled a History of some Northern Nations; but this assertion we have not discovered in that Work of his which commonly passeth amongst us, and should believe his Geography herein no more then that in the first line of his Book; when he affirmeth that _Biarmia_ (which is not seventy degrees in latitude) hath the Pole for its Zenith, and Equinoctial for the Horizon.
