Pliny's account, in the English version of 1601 (p. 587), runs: "To conclude, there is another mountaine in the same Æthyopia, and not farre from the said Zimiris, which breedeth the stone Theamedes that will abide no yron, but rejecteth and driveth the same from it." Martin Cortes, in his _Arte de Nauegar_ (Seville, 1556), wrote: "And true it is that Tanxeades writeth, that in Ethiope is found another kinde of this stone, that putteth yron from it" (Eden's translation, London, 1609).

Page 22, line 19. _quale_, altered in ink in the folio text to _qualis_. The editions of 1628 and 1633 both read _qualis_. [72] PAGE 22, LINE 19.

In the _De Re Metallica_ of Entzelt (Encelius), Frankfurt, 1551, p. 134, is a paragraph headed _De Rubrica Fabrili_, as follows: "Rubrica fabrilis duplex {25} est. à Germanis añt utraque dicitur rottel, röttelstein, wie die zimmerleüt vnd steynmetzen brauchen. à Græcis [Greek: miltos tektonikê]. Est enim alia nativa, alia factitia. Natiua à Germanis propriè dicitur berckrottel. haec apud nos est fossilis.... Porro factitia est rubrica fabrilis, à Germanis braunrottel, quæ fit ex ochra usta, ut Theophrastus et Dioscorides testantur." [73] PAGE 22, LINE 19. Page 22, line 20. _In Sussexia Angliæ._--In Camden's _Britannia_ (1580) we read concerning the iron industry in the villages in Sussex: "They are full of iron mines in sundry places, where, for the making and founding thereof, there be furnaces on every side; and a huge deal of wood is yearly burnt. The heavy forge-hammers, worked by water-power, stored in hammer-ponds, ceaselessly beating upon the iron, fill the neighbourhood round about, day and night, with continual noise." [74] PAGE 23, LINE 1. Page 22, line 44. _in libro Aristotelis de admirandis narrationibus._--The reference is to the work usually known as the _De Mirabilibus Auscultationibus_, Cap. XLVIII.: "Fertur autem peculiarissima generatio esse ferri Chalybici Amisenique, ut quod ex sabulo quod a fluviis defertur, ut perhibent certe, conflatur. Alii simpliciter lotum in fornace excoqui, alii vero, quod ex lotura subsedit, frequentius lotum comburi tradunt adjecto simul et pyrimacho dicto lapide, qui in ista regio plurimus reperiri fertur." (Ed. Didot, vol. ii., p. 87.) According to Georgius Agricola, the stone pyrimachus is simply iron pyrites.
