in this little book to follow Dr. Brinkley in
exact detail through his amazing list of cases of all manner of diseases
cured by this treatment. His files are open to the profession at all
times, and the records may be consulted by the earnest investigator at
the hospital at Milford, Kansas.

The intention in this little book is to cover particularly that phase of
human longing which asks that the clock be turned back, and that old age
be deferred.

It is a fact beyond all gainsaying that Dr. Brinkley's operation has in
truth cheated old age of its toll in very many cases of both sexes, and
the improvement, or rejuvenation, affects both the minds and bodies of
those treated by this method; and this rejuvenation is lasting to the
extent of the doctor's observation. It would be presuming to say that it
is a permanent improvement. Upon that point no one has any right to
offer an opinion, because there are no facts upon which to found it. But
Dr. Brinkley's earliest cases, operated upon three years ago, up to the
present time have shown no diminution whatever in the good effects
secured. Neither the women nor the men have lost any particle of their
increased vitality during this lapse of time. Who can say how long the
good effects will continue? Dr. Brinkley's opinion is that the
improvement will run for possibly fifteen years, at the end of which
time he expects to re-operate upon any cases that show a slowing-down in
the life-processes, and believes that the introduction of two new glands
after that time will result in a return of the vitality in full force as
before. That is his guess of the probable duration of the improvement,
but it is quite possible that his estimate errs on the side of
conservatism. There is one assuring and comforting fact, however,
bearing on this point, which should be carefully noted here, namely,
when a retransplantation was made by Dr. Brinkley upon a goat which had
first been cured of old age by transplantation of new glands, which was
allowed to retain this new adolescence for a year, and was then deprived
of the glands, causing a speedy return to the miserable condition of old
age and its ills, and which was then re-operated upon and given two new
glands, the instant improvement was every whit as noticeable and as
perfect in this second implantation as in the first. Now it is a
reasonable inference from this clear-cut result that Dr. Brinkley is
right in his opinion that a second transplant
