Pyrotechnical discourses. Containing, I. An experimental confirmation of chymical philosophy

The third title is problematical. The text is a translation of Metallurgiae pyrotechnicae et docimasiae metallicae fundamenta, written by Fritsch with Stahl as praeses. In Partington's bibliography p. 660, VII and p. 661, p. 661, XII, it appears that Stahl is the author.
