edition (1621-2). The recipe begins with
oil of roses, colophony, wax, and includes some twenty-two ingredients,
amongst them mummy, dried earthworms, and two ounces _lapidis magnetis
praeparati_. The recipe concludes: "Fiat Emplastrum secundum artem. Perquam
efficax ad recentia vulnera et puncturas, vnde denominationem habet." The
volume is a handsome folio not unlike Gilbert's own book, and bears at the
end of the prefatory address _ad Lectorem_ identically the same _cul de
lampe_ as is found on p. 44 of _De Magnete_.

The contradictions as to the alleged medicinal virtues of loadstone are
well illustrated by Galen, who in his _De facultatibus_ says that loadstone
is like haematite, which is astringent, while in his _De simplici medicina_
he says it is purgative.

emplastrum_.--Paracelsus's recipe for a plaster against stab-wounds is to
be found in _Wundt vund Leibartznei_ ... D. Theoph. Paracelsus (Frankf.,
1555, pp. 63-67).

[93] PAGE 33, LINE 17. Page 33, line 15. _Ferri vis medicinalis_.--This
chapter on the medicinal virtues of iron is a summary of the views held
down to that time. Those curious to pursue the subject should consult
Waring's _Bibliotheca Therapeutica_ (London, 1878). Nor should they miss
the rare black-letter quarto by Dr. Nicholas Monardus, of Seville, _Joyfull
Newes out of the New-found Worlde_, translated by John Frampton (London,
1596), in which are recited the opinions of Galen, Rhazes, Avicenna, and
others, on the medicinal properties of iron. In addition to the views of
the Arabic authors, against whom his arguments are directed, Gilbert
discusses those of Joannes Manardus, Curtius, and Fallopius. The treatise
of Manardus, _Epistolarum medicinalium libri viginti_ (Basil., 1549), is a
_resume_ of the works of Galen and the Arabic physicians, but gives little
respecting iron. Curtius (Nicolaus) was the author of a book, _Libellus de
medicamentis praeparatibus et purgantibus_ (Giessae Cattorum, 1614). The
works of Fallopius are _De Simplicibus Medicamentis purgentibus tractatus_
(Venet., 1566, 4to), and _Tractatus de Compositione Medicamentorum_
(Venet., 1570, 4to).
