Deep Sea Diving, &c., &c.

THE GREATEST DEPTH SAFELY ATTAINED. LATEST PRACTICE. The greatest authenticated depth at which divers have done practical work in safety is 35 fathoms—210 feet; this was accomplished by Lieut. G. C. C. Damant, R.N., Inspector of Diving in the British Navy, and Mr. A. Y. Catto, Gunner, R.N., in August, 1906, the operations being carried out under the personal supervision of Professor Haldane on behalf of the Admiralty, who appointed a Deep Diving Committee consisting of Captain F. T. Hamilton, R.N., M.V.O., President; Professor J. S. Haldane, M.D., F.R.S. ; Captain (now Admiral) Reginald H. S. Bacon, R.N., D.S.O., etc. , Captain Edgar Lees, R.N. ; the Secretary being Staff^Surgeon Oswald Rees, M.D., R.N., whilst Lieut. G. C. C. Damant, R.N., and Mr. A. Y. Catto, R.N., were appointed for the experimental work. A summary of the Committee s conclusions and recommendations is given on page 7. In conclusion, we would say that the reader may take it that the information given herein represents the very latest practice (similar to that adopted in the British Navy, whose divers are undoubtedly the most scientifically trained in the world), the result of the work of the eminent scientists and experts we have named, and of ourselves who have made a special study of the subject. Amongst other matters included in this book are articles on . THE EVOLUTION OF THE DIVING DRESS, DIVING BELL, etc. LIFE-SAVING DEVICES IN SUBMARINE BOATS. SALVAGE OPERATIONS. SELF-CONTAINED DIVING APPARATUS. SUBMARINE MINES. THE SAVING OF A CATHEDRAL BY DIVERS. SUBMARINE SIGNALLING. PEARL AND SPONGE DIVING. etc., etc. 6
