Excerpt from Animal Experimentation and Medical Progress I have been so frequently asked by earnest inquirers after truth for information as to animal experimentation, and especially for my own publications, that I have con cluded to publish these papers in a more permanent and accessible form than in medical and other journals. My thanks are due to the editors and publishers of the journals, etc., in which these papers first appeared, for permission to republish them in this volume. The papers appear in chronological order. Hence it is important that all their statements of methods, results, and statistics should be considered in connection with the date of the publication of each paper. In some cases I have given in footnotes later information and statistics. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
