"Yes?" I queried, for it was a mere name to me.
"It is a vascular organ lying under the chin with a sort of little isthmus joining the two parts on either side of the windpipe," he explained. "Well, when there is any deterioration of those glands through any cause, all sorts of complications may arise. The thyroid is one of the so-called ductless glands, like the adrenals above the kidneys, the pineal gland and the pituitary body. In normal activity they discharge into the blood substances which are carried to other organs and are now known to be absolutely essential.
"The substances which they secrete are called 'hormones'--those chemical messengers, as it were, by which many of the processes of the body are regulated. In fact, no field of experimental physiology is richer in interest than this. It seems that few ordinary drugs approach in their effects on metabolism the hormones of the thyroid. In excess they produce such diseases as exophthalmic goiter, and goiter is concerned with the enlargement of the glands and surrounding tissues beyond anything like natural size. Then, too, a defect in the glands causes the disease known as myxedema in adults and cretinism in children. Most of all, the gland seems to tell on the germ plasm of the body, especially in women."
I listened in amazement, hardly knowing what to think. Did his discovery portend something diabolical, or was it purely a defect in nature which Dr. Crafts of the Eugenics Bureau had overlooked?
"One thing at a time, Walter," cautioned Kennedy, when I put the question to him, scarcely expecting an answer yet.
That night in the old Atherton mansion, while we waited for Borroughs to arrive, Kennedy, whose fertile mind had contrived to kill at least two birds with one stone, busied himself by cutting in on the regular telephone line and placing an extension of his own in a closet in the library. To it he attached an ordinary telephone receiver fastened to an arrangement which was strange to me. As nearly as I can describe it, between the diaphragm of the regular receiver and a brownish cylinder, like that of a phonograph, and with a needle attached, was fitted an air chamber of small size, open to the outer air by a small hole to prevent compression.
The work was completed expeditiously, but we had plenty of time to wait, for Borroughs Atherton evidently did not consider that an evening had fairly begun until nine o'clock.
He arrived at last, however, rather tall, slight of figure, narrow-shouldered, designed for the latest models of imported fabrics. It was evident merely by shaking hands with Burroughs that he thought both the Athertons and the Burroughses just the right combination. He was one of those few men against whom I conceive an instinctive prejudice, and in this case I felt positive that, whatever faults the Atherton germ plasm might contain, he had combined others from the determiners of that of the other ancestors he boasted. I could not help feeling that Eugenia Atherton was in about as unpleasant an atmosphere of social miasma as could be imagined.
Burroughs asked politely after Eugenia, but it was evident that the real deference was paid to Edith Atherton and that they got along very well together. Burroughs excused himself early, and we followed soon after.
"I think I shall go around to this Eugenics Bureau of Dr. Crafts," remarked Kennedy the next day, after a night's consideration of the case.
The Bureau occupied a floor in a dwelling house uptown which had been remodeled into an office building. Huge cabinets were stacked up against the walls, and in them several women were engaged in filing blanks and card records. Another part of the office consisted of an extensive library on eugenic subjects.
Dr. Crafts, in charge of the work, whom we found in a little office in front partitioned off by ground glass, was an old man with an alert, vigorous mind on whom the effects of plain living and high thinking showed plainly. He was looking over some new blanks with a young woman who seemed to be working with him, directing the force of clerks as well as the "field workers," who were gathering the vast mass of information which was being studied. As we introduced ourselves, he introduced Dr. Maude Schofield.
"I have heard of your eugenic marriage contests," began Kennedy, "more especially of what you have done for Mr. Quincy Atherton."
"Well--not exactly a contest in that case, at least," corrected Dr. Crafts with an indulgent smile for a layman.
"No," put in Dr. Schofield, "the Eugenics Bureau isn't a human stock farm."
"I see," commented Kennedy, who had no such idea, anyhow. He was always lenient with anyone who had what he often referred to as the "illusion of grandeur."
"We advise people sometimes regarding the desirability or the undesirability of marriage," mollified Dr. Crafts. "This is a sort of clearing house for scientific race investigation and improvement."
"At any rate," persisted Kennedy, "after investigation, I understand, you advised in favor of his marriage with Miss Gilman."
"Yes, Eugenia Gilman seemed to measure well up to the requirements in such a match. Her branch of the Gilmans has always been of the vigorous, pioneering type, as well as intellectual. Her father was one of the foremost thinkers in the West; in fact had long held ideas on the betterment of the race. You see that in the choice of a name for his daughter--Eugenia."
"Then there were no recessive traits in her family," asked Kennedy quickly, "of the same sort that you find in the Athertons?"
"None that we could discover," answered Dr. Crafts positively.
"No epilepsy, no insanity of any form?"
"No. Of course, you understand that almost no one is what might be called eugenically perfect. Strictly speaking, perhaps not over two or three per cent. of the population even approximates that standard. But it seemed to me that in everything essential in this case, weakness latent in Atherton was mating strength in Eugenia and the same way on her part for an entirely different set of traits."
"Still," considered Kennedy, "there might have been something latent in her family germ plasm back of the time through which you could trace it?"
Dr. Crafts shrugged his shoulders. "There often is, I must admit, something we can't discover because it lies too far back in the past."
"And likely to crop out after skipping generations," put in Maude Schofield.
She evidently did not take the same liberal view in the practical application of the matter expressed by her chief. I set it down to the ardor of youth in a new cause, which often becomes the saner conservatism of maturity.
"Of course, you found it much easier than usual to get at the true family history of the Athertons," pursued Kennedy. "It is an old family and has been prominent for generations."
"Naturally," assented Dr. Crafts.
"You know Burroughs Atherton on both lines of descent?" asked Kennedy, changing the subject abruptly.
"Yes, fairly well," answered Crafts.
"Now, for example," went on Craig, "how would you advise him to marry?"
I saw at once that he was taking this subterfuge as a way of securing information which might otherwise have been withheld if asked for directly. Maude Schofield also saw it, I fancied, but this time said nothing. "They had a grandfather who was a manic depressive on the Atherton side," said Crafts slowly. "Now, no attempt has ever been made to breed that defect out of the family. In the case of Burroughs, it is perhaps a little worse, for the other side of his ancestry is not free from the taint of alcoholism."
"And Edith Atherton?"
"The same way. They both carry it. I won't go into the Mendelian law on the subject. We are clearing up much that is obscure. But as to Burroughs, he should marry, if at all, some one without that particular taint. I believe that in a few generations by proper mating most taints might be bred out of families."
Maude Schofield evidently did not agree with Dr. Crafts on some point, and, noticing it, he seemed to be in the position both of explaining his contention to us and of defending it before
