Prodromus of the Metallurgical Library

perly cannot be counted among the fossils of the macrocosm and the earth.

5. This Bibliotheca metallica shall hereafter, in time, produce a complete work in which one intends to extract the rare small pieces verbatim, but for the larger works, only to extract and briefly present their content, because many of them are rare and hardly to be had for money anymore, whereby the benefit to be hoped for and arising from them will then appear.

6. One will also be very pleased to receive and accept with deepest obligation everything that lovers of mining history and fossils might contribute to the aid of such a useful undertaking, for which one politely requests their assistance with due respect, and will never fail to be really thankful for it at every opportunity.

Wolfenbüttel,
the 2nd of January, 1732.
