Compressed Air Work And Diving 1909

VI PRE FACE. Wyman & Son, Fetter Lane, E.C., and in “ Preven- tion of Compressecl Air Illness," Vol. VIII., No. 3, June 1908, The [ournal of Hygiene, Cambridge Press. These two treatises contain information quite invalu- able to the engineer in charge of compressecl air work. I should like to take this opportunity of saying that I feel, and I am sure that every other engineer profession- ally interested in compressecl air work must feel also, that we are cleeply indebted to Dr Haldane, Dr Boycott, and Lieut. Damant, and also to Dr Leonard Hill and his colleagues, for the work they have done cluring the last few years, with the result of adeling so mueh to our knowledge of the preventive treatment of caisson sickness. Others who have also been goocl enough to help me, by supplying plans, giving permission to make extracts from their writings, and in other ways, are:—The Insti- tution of Civil Engineers; Mr Maurice Fitzmaurice, C.M.G., who supplied the drawings of Rotherhithe Tunnel; Mr Alfred Noble, who supplied the drawings of the East River Tunnels; Mr F.
