Many methods of experimentation he finds not only
extremely cruel, but valueless. For instance, the raising of the
blood-pressure of a dog by scorching its paws, one after the other, so
that the blood-pressure might be maintained for twenty minutes. `Of
what possible value was such an experiment?' he asks. `Does anyone
believe than in a human being, blood-pressure will ever be maintained
by slowly scorching the hands and feet of the patient?' ... The matter
is clearly presented, and is interesting to the layman as well as to
the student of physiology."--Hartford Post.

"The ethical problem of which Dr. Leffingwell writes in his
interesting and instructive book, is that which arises from the
prevailing practice of experimentation for scientific purposes upon
animals and human beings.... The book discusses what vivisection is,
and what have been the mistakes and abuses done in its name, as well
as the present unhappy conditions which surround the practice. The
author demonstrates that much of all this vivisection work is not only
unnecessary, but absolutely valueless to science. The book is to be
commended to all who would know something of what vivisection is, what
it does, and what is being done and should still be done to prevent
its present useless cruelty."--The Christian Register.

"Perhaps no other man in America has so good a right to speak on
vivisection, from the standpoint of an expert, as Dr. Leffingwell. To
our mind, he has here gathered in a forceful way the last sane word to
be said on this sensitive question. In these nineteen chapters he has
discussed almost every phase of the problem. Dr. Leffingwell has
occupied a difficult position, standing as he does midway between the
contending parties.... He discovers the law of cruelty, and applies it
mercilessly. He also discovers the law of sacrifice, and would apply
it humanely. In short, this book may well be taken as an
encyclopaedia on vivisection, looked at from the standpoint of the
moralist and the physician. There are illminating appendices giving
technical information, and the chapters are characterized by vigorous
England, and a lively sense of a physician's obligations."

"If nothing else in the book were to be remembered, it would be
valuable that all earnest people should consider the careful analysis
of the various positions which have been taken in regard to this
position, and the critical definition with which Dr. Lef
