This, we say it regretfully, is the end of Mr. Day’s article. It is admirable fooling. We will not pay his wit the poor compliment of taking him seriously at the last and pointing out to him that it was Heine who said, “Nobody loves life like an old man!” There will be no need of insistence to urge the old men, useful or useless, to submit to an operation to renew their youth. But it is to be hoped that they will never be asked to submit to the cutting of the genital duct. It seems to the writer that The Athenaeum must have misconstrued Dr. Steinach’s experiments in some degree, inasmuch as it is difficult to conceive of the operation of severing a genital duct as conducive to cell-formation. However, probably ligating is meant instead of severing. But this is not the point really brought out by Mr. Day’s clever article. The real point is, Is it likely that if Mr. John Jones takes Dr. Brinkley’s goat-gland operation for the renewal of his youth, and thereby adds thirty years to his life, and at the end of this thirty years of friskiness undergoes a second transplantation of glands, thereby gaining twenty years more, and at the end of this twenty years takes the operation a third time, securing a further lease of gaiety for ten years, will the final years of Mr. John Jones be years of acute psychic senility, as observed by Dr. Steinach in his rat? To the writer it seems a non sequitur.

The cases are not parallel. The rejuvenated rat appears to regard his acquired vitality as impelling toward revelry and excess. It is necessary to emphasize the point that the pith and marrow of Dr. Brinkley’s discovery is that since it is clearly shown that rejuvenation is accomplished by the restoration of activity to the sex-glands, therefore the preservation of this rejuvenation MUST depend upon the CONSERVATION of the seminal fluids, and cannot depend upon any other single factor whatever. It has been already explained that Dr. Brinkley puts it out of the power of the rejuvenated man to destroy the good that has come into his life, and protects him against the danger of yielding too freely to passionate impulse, by preventing the escape of the rejuvenating agent. The means of nourishing the body and brain being therefore insured as to supply, it is not reasonable to suppose that the nerve-cells of the rejuvenated man can fail to receive their proper nourishment for many succeeding years, and, passing by the rat as a fallacious parallel, we cannot see any good reason why the human body and brain, either under the guidance of self-control, or surgically safeguarded against the waste of excess, should not function at their best for fifty years of added life, with very possibly another fifty added to that. The real crux of the matter is the resistive quality of tissue, which is approximately 200 years for such organs as kidneys and heart, and, say, 150 for nerve-substance.

THE OPERATING ROOM AT THE BRINKLEY HOSPITAL

[CHAPTER VIII]

A WEEK AT DR. BRINKLEY’S HOSPITAL

The writer, approaching the age of 54, and finding himself in first-class physical and mental condition, except for a high blood pressure, which was certainly the prelude to a later arterio-sclerosis, decided that he would be doing himself a service, and put himself in a better position to write with some authority upon the effects of the goat-glands, if he took the operation.

On Saturday, April 16. 1921, Dr. Brinkley operated on him at the hospital, Milford, Kansas, transplanting the glands of a three-weeks old male goat. He remained in bed Saturday and Sunday, got up and went for an auto drive on Monday, and passed an uneventful week at the hospital, returning to Chicago on Saturday. He experienced a marked increase in mental energy, which might have shown itself also as increased physical energy if it had been put to the test. This feeling of added pep, snap, energy, or what you please to call it, could be psychological in its origin if it were not for the fact that it is continuous, with no set-backs. Every student of psychology is aware that auto-suggestion has the power to bring out latent energy, raise the drooping spirits, and generate a feeling of well-being. But the student, if he is a reasonably close observer, is also aware that these improved

states of feeling have an annoying habit of being offset by corresponding periods of depression, and though he may persist in his effort to lift himself out of the black moods with such success that he finally arrives at a higher tone-level mentally, with a corresponding physical improvement, there is indubitably a strong sense of effort needed for this good result. When, therefore, the writer finds himself working long hours day after day with no sense of mental fatigue, but a certain unusual gaiety of heart accompanying the successive days, as if life were on the whole rather a lark, he, being accurately introspective, and not easily deceived into optimistic conclusions, is forced to give the whole credit for this change of spirit to the functioning of the new glands, and he is confirmed in this conclusion by the fact that the high blood pressure, which was noticeable enough before the operation, cannot now, ten days after the operation, be detected by him at all. Ten days is all too short a time in which to write of details in a matter of this importance. He expects to be able to confirm improvement in eyesight by the middle of May, and will be in a position to speak at greater length on the matter after the summer has passed. The intent of this chapter is to give a brief account of something he saw at Dr. Brinkley’s hospital during the week of his treatment.

Two weeks before his arrival a man suffering from locomotor ataxia had been carried in, unable to help himself at all. When the writer saw this man and talked with him he was up
