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 Ernst, and received other letters, not for publication, in which the old gentleman went frankly into details of the change that had been wrought in him by the operation in the matter of astonishing sexual vigor.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.

THE STORY OF CHANCELLOR TOBIAS

We must go to the pages of The Chicago Evening American of date August 18, 1920, for the story of Chancellor Tobias, written by Lloyd Lehrbas, of the American staff, with a brief introductory note, as follows:

(Here is one of the most remarkable news stories ever published in any Chicago newspaper. So startling is its detail that The Chicago Evening American in the interest of absolute accuracy submitted it to the person most concerned for his approval, so there can be no question concerning the facts, scientific or otherwise. Other men and women involved are not mentioned because the facts being established in the most important case, it is not considered necessary.)

Goat interstitial gland operations have been successfully performed on J. J. Tobias, Chancellor of the Chicago Law School, and thirty-five other Chicago men and women by Dr. J. R. Brinkley, of Milford, Kansas, who has been in Chicago for the past six weeks, performing the operations every day.

An alderman, a well-known political figure, living on the Gold Coast, a judge, a prominent real estate man, a newspaper man, three women, one of whom is well known on the North Shore, and other Chicagoans, have found the lost Fountain of Youth as a result of the
