O. ▼On Lippmann, of Halle, haa collected evidence to indicate that this is a mistake, and that the Arabians did not, as commonly stated, introduoe gunpowder into Europe during the eighth and ninth centuries. Professor von Lippmann be- lieves that the manufacture of the first gun- powder was based upon the Fire-book" of Greecus, which appeared in Constant* nopfr about the middle of the thirteenth ce ar- tery. Thia was the source from which Roget Bacon, Albertus Magnus, and Thomaa Aquinas derived their knowledge of gunpowder. The first Me of gunpowder to drive projectiles is ascribed be a monk, BerLold Schwarz, whose discovery was made accidentally while preparing the JIIIÎII. tare for medicinal purposes.
