Preface.
Our reasons for writing this book will be explained by the book itself. We desire here gratefully to acknowledge the help of several friends who have considerably facilitated our task. Our thanks are due to Major R. G. Rows, M.D., R.A.M.C., for his unfailing interest, encouragement and help; to Captains W. H. R. Rivers, M.D., F.R.C.P., F.R.S., and J. W. Astley Cooper of the R.A.M.C., and Mr. E. Gleaves, M.Sc., for their valuable suggestions and assistance in the preparation of the manuscript; to Captain W. E. Sawers Scott, M.D., R.A.M.C., Dr. Albert Hopkinson and Mr. W. Percy Stocks, F.R.C.S., of Manchester, for help in other ways; and to our colleague, Professor H. Bompas Smith, for reading the proofs and helping us to eliminate some of the more glaring literary defects. To the Editor of the Lancet we are indebted for permission to use part of an article written by one of us. The stream of requests for fuller information and explanation that poured in upon the author of that article made the writing of this book an unavoidable duty.
