ANAESTHETIC MACHINE - This detail is taken from the Clark New Model Gas apparatus manufactured by the Western Dental Manufacturing Company of Great Portland Street, London, Bristol and Cardiff. Illustrated in their 1924 catalogue, the equipment was described as the most perfect gas apparatus ever produced and eminently suitable not just for general anaesthesia but for analgesia as well. The great feature of this machine lies in the construction of the mixing chamber in which the N2O and oxygen gases come into contact no less than four times. The method of control is through a single handle on the mixing chamber. (Photographed at the BDA Museum by Filip Gierlinski. www.fi lskifoto.com)
