I'm most interested in your hypothesis, and have passed the suggestions on both to the new Director of the Commonwealth Serum Laboratories, Dr. Neville McCarthy, and to the appropriate authorities in the University of Queensland who are in charge of the research station at Heron Island. If anything turns up from these enquiries, I shall naturally forward it to you forthwith. With warm good wishes,
