ANOTHER PRIESTLEY DOCUMENT This medal (silver, 53.5 mm. diameter) is an especially interesting document of the history of chemistry in America, for it commemorates Priestley's departure from England and gives the date of that departure and the date of his arrival in this country. "April 8-Leaving the Shores of Brittannia He Went to Columbia-June 4, 1794." The medal appears to be rare. The Stadtliche Munzkabinet a t Dresden has a bronze medal, of which Professor Lyman C. Newell has shown us a plaster cast, which is of the same size as the present medal, like it on the obverse, and like it on the reverse as regards the central portion of the medal but different from i t in the respect that it has the words, Magnus Christianus Philosophus (Great Christian Philosopher), next to the circumference where the present medal has the words, I Decus I Nostrum Melioribus Utere Fatis (Go, Our Ornament, Go to Take Advantage of Better Fates). Numerous medals, and the penny and half-penny tokens which bear the effigy of Priestley, give evidence of the widespread popularity which his ideas had in England. The present medal shows that he left behind him those who viewed his removal to this country with real regret. (Contributed by Tenney L. Davis.)
