n 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.

"Readers of Dr. Leffingwell's earlier books will expect to find this
one written in the same quiet tone, with the same care and accuracy,
and they will not be disappointed. The book begins with a history of
vivisection in which the reader's chief suprise will be in finding
that medical opinion a generation ago was much more humane than now.
The humane protests of the last generation seem incredible to-day,
when the profession almost to a man stands for the secvret and
unlimited exploitation of animals."--S. N. Cleghorn, in Journal of
Zoophily.

"This book is devoted to a study and discussion of medical
experimentation upon both man and animals. The writer is forced in
his literary style, and has long commanded special attention on this
particular subject. In a skilful and scholarly manner he treats of
the historical development of the agitation in favour of restricted
and regulated experimentation. The book should be read by every
person interested in the discussion, whether in favour of restriction
or not.... All who desire to be placed in touch with the latest word
in regard to this important humanitarian question should secure a copy
of Dr. Leffingwell's scholarly book."--National Humane Review.

"Dr. Leffingwell analyzes the results of vivisection in America in a
masterly way.
