xceedingly precise and well written, fortifying itself
with abundant particulars. It touches the hideous cruelties and
devilish atrocities which are done upon various animals, and behind
well-closed doors. One reads it with intense pain and a disgust which
combines nausea with indignation toward the ruthless experimenters
who, disclaiming the hindering use of anaesthetics, exhibit all the
phenomena of nervous torment. Monsters of research would sneer aside
all critics of such infernal `physiological' laboratories....

"The book is a protest against the careful and subterranean silence
and concealment which seem to conspire to resist all legal
inspection. To evade or baulk investigation while causing pain in
order to exploit it, to jeer at the humane shudder of the layman, to
utilize feeble-minded paupers and friendless young children, to
sophisticate a too credulous public with an austere formula as to the
sacred secrecy of the laboratory--all this is an attempted HYPNOSIS of
critics who really want to be fair, but who as citizens insists upon
the right to know what is doing.

"The title of the book--`An Ethical Problem'--is indeed justified by
its array of evidence and argument. Particularly is it shown that on
this question America is still in the dark ages. Reform demands a
frank exactitude as to the practices which, if Dr. Leffingwell is
substantially accurate, are a disgrace to humanity. State control
cannot always be avoided by ridiculing the `sentimentality' of those
who insist upon strict regulation. Painless vivisection for
investigation may have its legitimate place; but to illustrate what is
already well ascertained by exhibiting animals in agony is both
superfluous and debasing, repellant to every mind not seared by a
morbid curiousity."--Hamilton College Record

"`An Ethical Problem,' by Albert Leffingwell, M.D., is by far the most
judicial and unimpassioned contribution to the study of the question
that it has been our privilege to read. Dr. Leffingwell has long been
known both in this country and Europe, as a writer upon this theme.
No one, so far as we know, has brought to it at once so calm and
balanced a judgment as he, or a more exact knowledge of the whole
field in which biological investigation plays so large a part. This
latest publication from his pen is the result of years of study, of
unremitting toil in the great libraries of this country and abroad
where every facility was at hand
