title: Doctor Dee's ether apparatus.
abstract: In the early 1940s, Dr M. H. Armstrong-Davison devised an apparatus for inhalational anaesthesia. The apparatus was essentially a combination of Water's to-and-fro soda-lime canister and Hewitt's ether inhaler. The description of the apparatus is followed by a brief historical note on Dr Armstrong-Davison.
