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 _résumé_ 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 præparatibus et purgantibus_ (Giessæ Cattorum, 1614). The works of Fallopius are _De Simplicibus Medicamentis purgentibus tractatus_ (Venet., 1566, 4to), and _Tractatus de Compositione Medicamentorum_ (Venet., 1570, 4to).

In the splendid folio work of Rhazes publisht at Venice in 1542, with the title _Habes candide lector Contin[~e]tem Rasis_, Libri ultimi, cap. 295, under the heading _De Ferro,_ are set forth the virtues of iron slag: "Virtus scorie est sicut virtus scorie [a]eris sed debilior in purgãdo: et erugo ferri est stiptica: et c[~u] superpositur retinet fluxus menstruor[~u].... Ait Paulus: aqua in qua extinguitur ferr[~u] calens.... Dico: certificatus sum experientia [~q] valet contra emorryodas diabetem et fluxum menstruorum."
