ation, and have only a memory
of my former suffering. This is a marvelous thing. I have the feeling of
a youth. Whenever you want to hear from me I will write again and tell
you what changes have taken place in me as the result of this operation.
If I was asked to put a cash value upon the operation in my own case I
could not do it, but I can say that all I possess in cash would be a
poor equivalent for the difference the operation has made in my life.
What is the difference in cash value between a life that is worth living
and one that is constant misery? I don't know how you would fix that
value, but that is the difference the operation has made in me.

S. H. ERNST."

Dr. Brinkley has kept in close touch with Mr. Ernst, and received other
letters, not for publication, in which the old gentleman went frankly
into details of the change that had been wrought in him by the operation
in the matter of astonishing sexual vigor. For obvious reasons such
details, while of the greatest scientific interest, cannot be more than
hinted at in a book, and we must content ourselves with the acceptance
of the fact as a fact of interest to science, to Dr. Brinkley, to the
world of aged men at our doors, and to Mr. Ernst particularly, rejoicing
in his new-found vigor.

Apart from the genuinely happy tone of his letters to Dr. Brinkley, the
phenomenon of the darkening of the hair strikes most sharply on the
attention. Perhaps our satisfaction in this particular piece of evidence
of rejuvenation is due to the fact that it is an objective proof;
something visible to the eye, tangible; something for which we are not
required to take anybody's opinion, but can trust our eyesight for the
fact of it. It is something in which the psychic factor, the feelings,
the imagination, the auto-suggestion, does not enter at all, and that is
why it is exceedingly well worthy of note. Looking back over the years,
and casting up in your minds all the people of sixty and seventy years
of age whom you have known, can you put your finger on a single one
whose hair turned in color from white to dark and at the same time from
thin to thick? You probably cannot. Nor can the writer. It is reasonable
to conclude, therefore, that the goat-glands alone have done this thing
in the case of Mr. Ernst.
