Some further study of a primary spelling-book might be recommended to this representative of an institution of learning. The institutions making no reply of any kind numbered eighty-eight, or about 83 per cent. of those addressed. The inquiry resulted in confirming previous impressions. It was not believed that information concerning the number of animals used would be generally given. The experiment of courteous inquiry, however, was deemed worthy of a trial. The result would seem to demonstrate that even the simplest facts concerning the practice of animal experimentation in the United States cannot be obtained except through inquiry instituted by the authority of the State. AN ETHICAL PROBLEM OR SIDELIGHTS UPON SCIENTIFIC EXPERIMENTATION UPON MAN AND ANIMALS --------------- PRESS NOTICES "Dr. Leffingwell has probably done more than any other one man for the education of the public to a right attitude on the vivisection question."--Dallas News. "The author has studied this question for forty years. He shows by the material gathered in this volume and the interesting conclusions reached, the careful consideration of long years of study."--Detroit News Tribune. "The author's moderation in discussing this burning question will appeal to a much wider circle of scientific readers than a policy that demands complete annihilation of all animal experimentation."--The Open Door, New York. "The volume deals with vivisection, and the author holds that it is to preventive medicine that the world must learn to look, not to the conquest of disease by new drugs or new serums.... He enters deeply into the question, and shows the result of long and careful research work."--Norwich Bulletin "In an elaborate discussion of the vexed question of vivisection, Dr. Leffingwell tries to take a mediating position. He is strong in showing that there has been a vast amount of needless and useless suffering to animals caused by vivisection.... Some of his quotations are amazing in showing the indifference and even cold-blooded cruelty of some surgeons."--New York Watchman. "One of the most thorough books on vivisection yet published is by Dr. Albert Leffingwell, entitled `An Ethical Problem.' It is not the book of an extremist or a crank. Dr. Leffingwell admits the necessity of vivisection in certain circumstances and for certain purposes. His endeavour is not so much to get rid of vivisection as to prove that the problem connected with it is an ethical one; that the practice should be regulated and guided by public authority. His book is thorough, ingenious, and, for the most part, very temperate in expression."--The New York Evening Mail.
