See Ferreous.] (Chem.) Defn: Pertaining to, or derived from, iron; -- especially used of compounds of iron in which the iron has its lower valence; as, ferrous sulphate.

Many relations are made, and great expectations are raised from the _Magnes Carneus_, or a Loadstone, that hath a faculty to attract not only iron but flesh; but this upon enquiry, and as _Cabeus_ also observed, is nothing else but a weak and inanimate kind of Loadstone, veined here and there with a few magnetical and ferreous lines; but consisting of a bolary and clammy substance, whereby it adheres like _Hæmatites_, or _Terra Lemnia_, unto the Lips.

True it is that in the making of Glass, it hath been an ancient practice to cast in pieces of magnet, or perhaps manganes: conceiving it carried away all ferreous and earthy parts, from the pure and running portion of Glass, which the Loadstone would not respect; and therefore if that attraction were not rather Electrical then Magnetical, it was a wondrous effect what _Helmont_ delivereth concerning a Glass wherein the Magistery of Loadstone was prepared, which after retained an attractive quality.

Unto the ferreous and mineral quality pertaineth what _Dioscorides_ an ancient Writer and Souldier under _Anthony_ and _Cleopatra_ affirmeth, that half a dram of Loadstone given with Honey and Water, proves a purgative medicine, and evacuateth gross humours.

And if we yet make a more exact enquiry, by what this salt of vitriol more peculiarly gives this colour, we shall find it to be from a metalline condition, and especially an Iron Property or ferreous participation.
