With the limited space, only one academic appointment was made while we were in Melbourne. Stephen Fazekas de St Groth completed his term of appointment with Burnet in December 1951. Burnet did not wish to reappoint him, but I was impressed by his intelligence and dedication and offered him a Senior Research Fellowship. I obtained laboratory accommodation for him in the laboratories of the Children's Hospital, where he continued studies on influenza virus. For assistance with my studies on mycobacteria, I appointed Ronald Leach as a research assistant in 1950. He stayed with me until the embryo Department moved to Canberra. In 1951, Gwen Woodroofe and Ian Marshall were appointed as research assistants to help me with work on myxomatosis.
