F45 P14 1912 PREFACE THIS book was written at the request of the Committee of the Research Defence Society. All of it, except the Introduction by Lord Cromer, and the last chapter, was seen through the press long before the Royal Commission on Vivisection published its final Report. It is hoped that the book gives a clear account of the chief results obtained, during the past thirty years, by the help of experiments on animals. So far as possible, this account has been stated in the very words of the men who did the work. They described, from actual experience, decisive events in the Thirty Years' War against the diseases of man and of animals. It is certain that the history of that war is of unfailing interest.
