[774] Digby 162, 13th century, fols. 10v-11v, “Incipit liber Aristotelis de aquis secreti fluminis translatus ab arabico in latinum.” In the margin the twelve waters are briefly designated: 1 rubicunda, 2 penetrativa, 3 mollificativa, et ingrediente, 4 de aqua eiusdem ponderis et magnitudinis, 5 ignita, 6 sulphurea, 7 aqua cineris, 8 aurea, etc. In one or two cases, however, these heads do not quite apply to the corresponding chapters.

[775] Ashmole 1448, 15th century, pp. 200-202, de “altitudinibus, profundis, lateribusque” metallorum secundum Aristotelem (name in the margin). It opens, “Plumbum est in altitudine sua ar. nigrum.” It takes up in turn the altitudo of each metal and then discusses the next quality in the same way.

Ibid., pp. 239-44, opens, “Arestotilus, Cum studii, etc. Scias preterea quod propter longitudines”; at p. 241 it treats “de purificatione solis et lune” (i.e., gold and silver); at p. 243, “de separatione solis et lune.” It ends with a paragraph about the composition of a golden seal.
