Abstract

SUMMARY: This article contains a number of facts about Treffz, who was born in Hessen (Germany) and who was since 1791 in Batavia. In 1815 he was there in the service of the Dutch East India Company, but it is almost certain that this was the case in 1791 too. Treffz travelled to the Moluccos in 1820 to collect objects of Natural History. He died June 18, 1820 on his return from Ceram to Amboina. He went before Reinwardt to that part of the Indonesian Archipelago, Reinwardt left Batavia February 21, 1821 and came back to Buitenzorg March 18, 1822. Information is given about persons, who contributed to the collections of the Dutch musea of Natural History at Amsterdam and Leyden. The collections at Amsterdam were added to those at Leyden in 1820.
