A dog scratching its ear. Bronze sculpture, 1993.

"The Society's insignia, a bronze sculpture of a dog exhibiting the scratch reflex, was presented to The [Physiological] Society by Sir Henry Dale in October 1942. … The dog, created by an unknown renaissance sculptor, was originally given to the German physiologist Rudolph Magnus (1873–1927) by his father. Magnus subsequently gave the dog to Sir Charles Sherrington (1857–1952) who kept it for many years on the mantelpiece of his room in Oxford. When he left Oxford, he passed on the dog to Sir Henry Dale (1875–1968). On leaving his laboratory at the National Institute for Medical Research, Dale, in turn, presented the dog to The Physiological Society, mounted on a plinth, with the inscription 'Rudolph Magnus gave me to Charles Sherrington, who gave me to Henry Dale, who gave me to The Physiological Society in October 1942.' ... Replicas of the dog are given to retiring officers and distinguished members of The Society." (The Physiological Society website, 2014). The original bronze was stolen in 1994
