Note 892 — COLLECTIONS OF NATURAL CURIOSITIES.

With how much care this learned man, who died in 1544, in the twenty-ninth year of his age, collected minerals and plants is proved by his Silva Observationum Variarum, quas inter peregrinandum brevissime notavit. Walch, in his Naturgeschichte der Versteinerungen, considers it as the first general oryctography of Germany, and is surprised that so extensive a work should have been thought of at that period. Wallerius, in his Lucubratio de Systematibus Mineralogicis, Hohniæ, 1768, 8vo, p. 27, considers this Silva as a systematic description of all minerals. Both however are mistaken. Cordus undertook a journey in 1542, through some parts of Germany, and drew up a short catalogue without order, of the natural objects he met with in the course of his travels, which was published by Conrad Gesner, together with the other works of this industrious man, at Strasburg in 1561. This book, which I have in my possession, has in the title page, In hoc volumine continetur Valerii Cordi in Dioscoridis libros de Medica Materia; ejusdem Historiæ Stirpium, &c. The Silva begins page 217.
