ealth, or a state of disease; beauty of form and feature and skin, or
wrinkles, sallowness and ugliness. These appearances and qualities are
phenomena which have the same source, or base. Many have felt this to be
true. Dr. Brinkley alone has had the wit and skill to find the means to
solve the problem as it should be solved to be of any value to humanity,
namely, to discover how the inactivity can be changed to activity, how
the blood of man and woman can be charged anew with the life-giving
hormones, perhaps, or whatever may be the name of that substance
secreted by the sex-glands and used by the blood to nourish all the
cells of the body, which MUST be present in the system if body and mind
are to continue to function at their best.

CHAPTER II

THE PRACTICE. MEN

Dr. Brinkley began his experiments in gland-transplanting upon animals
in the year 1911, three years before the European War, using goats,
sheep, and guinea-pigs as his subjects. He ran beyond the limits of his
resources in this experimental work on animals, which was interrupted by
his enlistment in the army, and assignment to service as First
Lieutenant in the Medical Corps. Passed fit for Foreign Duty he was
nevertheless unable to get across to France, and remained, like many
another good surgeon, on duty in various southern camps.

Returning to civilian life he took up his quest again, varying a general
medical and surgical practice by continued observation and experiment in
gland-transplantations upon animals, leaning ever more strongly towards
the exclusive use of goats. About this time he heard of the work of
Professor Steinach of Vienna in grafting the glands of rats, and
producing changes in the character and appearance of the animals by
inverting the process of nature and transplanting male glands into
females, and vice versa, sometimes with success. He had followed with
the greatest interest also the experiments of Dr. Frank Lydston of
Chicago, who performed his first human-gland transplantation upon
himself, an example of courage that falls not far short of heroism. But
Dr. Brinkley was never favorably impressed with the idea of using the
glands of a human being for the renovation of the life-force of another
human being. He was looking to the young of the animal kingdom to
furnish him with the material he proposed to use to improve the
functioning of human organs, and more certainly as time pa
