ssed he drew
to the conclusion that in the goat, and in the goat alone, was to be
found that gland-tissue which, because of its rapid maturity, potency,
and freedom from those diseases to which humanity is liable, was most
sure under right conditions of implantation to feed, nourish, grow into
and become a part of, human gland-tissue.

Later we will dwell a little upon some of his results. It is worthy of
note in passing that his first experiment upon a human being was an
unqualified success. He transplanted the goat-glands into a farmer who
was forty-six years of age, happily married, but childless, and one year
after the transplantation a child was born, who was christened "Billy"
in honor of the circumstances responsible for his birth. By patient
selection Dr. Brinkley has found that the Toggenburg breed of Swiss goat
gives him the best possible stock to use in his gland-work. This choice
was forced upon him by results obtained by the use of other breeds. He
found that the Toggenburg goat gave him best results because the animal,
besides its sound health, carries none of that persistent odor which is
peculiar to male goats the world over, and which, if shed abroad by a
human being would make his neighborhood unpleasant. He found that the
best age of the male goats whose glands were to be transplanted was from
three weeks to a month. He found that the best age at which to use the
ovaries of the female goat was one year, because, unlike its youthful
brother, the female goat's sex-activities are not developed before that
age.

His method of transplanting the glands into a man is by making two
incisions in the man's scrotum under simple local anesthesia,
a practically painless operation, but from this point on the technique
varies according to the conditions presented by the case. No two cases
are exactly alike, and Dr. Brinkley performs no two operations exactly
alike. That is the reason, he explains, why, with the best will in the
world to teach his fellow-practitioners what to do and how to do it, he
is nevertheless unable to state in writing exactly what treatment to use
to cover all cases. It cannot be taught by correspondence, and, simple
though it sounds to hear it, it cannot be learned by attendance at a few
clinics. It is delicate in this sense, that if it is not rightly
performed in the individual case the glands will slough. That means loss
of time, loss of temper, and the waste of a perfectly good pair of yo
