Sir Thomas Browne, in an undated letter to Mr. Elias Ashmole (Works, ed. 1852,
vol. III., p. 530) relating a conversation he had with Dr. Arthur Dee, goes on to say:—
“I have heard the Dr. saye that hee lived in Bohemia with his father, both at
Prague and other parts of Bohemia. The Prince or Count Rosenberg was their
great patron, who delighted much in alchymie; I have often heard him affirme, and
sometimes with oaths, that hee had seen projection made and trasmutation of
pewter dishes and flaggons into sylver, which the goldsmiths at Prague bought of
them. And that Count Rosenberg playd at quaits with silver quaits made by
projection as before; that this transmutation was made by a powder they had,
which was found in some old place, &c.”
