Abstract:
This item is part of a series of operational records from the Zoological Research Supply Company, specifically regarding permits and licenses. The ZRS served as the profit-making subsidiary of the Bass Biological Laboratory, and operated in the mid to late 1930s and early 1940s. This letter from W. G. Workman of the Division of Biologics Control to Donald Brooks Powell discusses regulations for the sale of viruses, serums, toxins, and analogous products.
