A symposium on virus and rickettsial diseases was held at the Harvard Medical School in the summer of 1939. The published compilation of that symposium contains contributions from such eminent authorities as Zinsser, Gordon, Russell, C. K. Drinker, McKhann, Aycock and Fothergill. It represents an invaluable contribution to the summarization of present knowledge of viruses and diseases caused by them.
