Note 559 — PHARMACOLOGIA. (continued 5)

Magnesia was originally a general term, expressive of any substance which had the power of attracting some principle from the air, from Magnes, the Loadstone. The peculiar body which we now denominate Magnesia, was first sold as a panacea, by a canon at Rome, in the beginning of the seventeenth century, under the title of Magnesia alba, or Count Palma’s Powder.
