The Larmor Lecture which was to be delivered by Professor Nick E. Day, FRS, entitled Epidemiology - where are the limits?, and intended to be held in the Cockcroft Lecture Theatre, New Museums Site, on 17 October at 8.30 p.m, has unfortunately been cancelled. This lecture was a joint meeting with the Cambridge Society for the Application of Research. It is hoped to reschedule the Larmor Lecture at a later date.
