long enough for Professor Kennedy to say a few words about Eugenia," replied Atherton nervously, bowing to Kennedy.

      Kennedy cleared his throat slowly.

      "I don't know that I have much to say," began Kennedy, still seated. "I suppose Mr. Atherton has told you I have been much interested in the peculiar state of health of Mrs. Atherton?"

      No one spoke, and he went on easily: "There is something I might say, however, about the--er--what I call the chemistry of insanity. Among the present wonders of science, as you doubtless know, none stirs the imagination so powerfully as the doctrine that at least some forms of insanity are the result of chemical changes in the blood. For instance, ill temper, intoxication, many things are due to chemical changes in the blood acting on the brain.

      "Go further back. Take typhoid fever with its delirium, influenza with its suicide mania. All due to toxins--poisons. Chemistry-- chemistry--all of them chemistry."

      Craig had begun carefully so as to win their attention. He had it as he went on: "Do we not brew within ourselves poisons which enter the circulation and pervade the system? A sudden emotion upsets the chemistry of the body. Or poisonous food. Or a drug. It affects many things. But we could never have had this chemical theory unless we had had physiological chemistry--and some carry it so far as to say that the brain secretes thought, just as the liver secretes bile, that thoughts are the results of molecular changes."

      "You are, then, a materialist of the most pronounced type," asserted Dr. Crafts.

      Kennedy had been reaching over to a table, toying with the phonograph. As Crafts spoke he moved a key, and I suspected that it was in order to catch the words.

      "Not entirely," he said. "No more than some eugenists."

      "In our field," put in Maude Schofield, "I might express the thought this way--the sociologist has had his day; now it is the biologist, the eugenist."

      "That expresses it," commented Kennedy, still tinkering with the record. "Yet it does not mean that because we have new ideas, they abolish the old. Often they only explain, amplify, supplement. For instance," he said, looking up at Edith Atherton, "take heredity. Our knowledge seems new, but is it? Marriages have always been dictated by a sort of eugenics. Society is founded on that."

      "Precisely," she answered. "The best families have always married into the best families. These modern notions simply recognize what the best people have always thought--except that it seems to me," she added with a sarcastic flourish, "people of no ancestry are trying to force themselves in among their betters."

      "Very true, Edith," drawled Burroughs, "but we did not have to be brought here by Quincy to learn that."

      Quincy Atherton had risen during the discussion and had approached Kennedy. Craig continued to finger the phonograph abstractedly, as he looked up.

      "About this--this insanity theory," he whispered eagerly. "You think that the suspicions I had have been justified?"

      I had been watching Kennedy's hand. As soon as Atherton had started to speak, I saw that Craig, as before, had moved the key, evidently registering what he said, as he had in the case of the others during the discussion.

      "One moment, Atherton," he whispered in reply, "I'm coming to that. Now," he resumed aloud, "there is a disease, or a number of diseases, to which my remarks about insanity a while ago might apply very well. They have been known for some time to arise from various affections of the thyroid glands in the neck. These glands, strange to say, if acted on in certain ways can cause degenerations of mind and body, which are well known, but in spite of much study are still very little understood. For example, there is a definite interrelation between them and sex--especially in woman."

      Rapidly he sketched what he had already told me of the thyroid and the hormones. "These hormones," added Kennedy, "are closely related to many reactions in the body, such as even the mother's secretion of milk at the proper time and then only. That and many other functions are due to the presence and character of these chemical secretions from the thyroid and other ductless glands. It is a fascinating study. For we know that anything that will upset- -reduce or increase--the hormones is a matter intimately concerned with health. Such changes," he said earnestly, leaning forward, "might be aimed directly at the very heart of what otherwise would be a true eugenic marriage. It is even possible that loss of sex itself might be made to follow deep changes of the thyroid."

      He stopped a moment. Even if he had accomplished nothing else he had struck a note which had caused the Athertons to forget their former superciliousness.

      "If there is an oversupply of thyroid hormones," continued Craig, "that excess will produce many changes, for instance a condition very much like exophthalmic goiter. And," he said, straightening up, "I find that Eugenia Atherton has within her blood an undue proportion of these thyroid hormones. Now, is it overfunction of the glands, hyper-secretion--or is it something else?"

      No one moved as Kennedy skillfully led his disclosure along step by step.

      "That question," he began again slowly, shifting his position in the chair, "raises in my mind, at least, a question which has often occurred to me before. Is it possible for a person, taking advantage of the scientific knowledge we have gained, to devise and successfully execute a murder without fear of discovery? In other words, can a person be removed with that technical nicety of detail which will leave no clue and will be set down as something entirely natural, though unfortunate?"

      It was a terrible idea he was framing, and he dwelt on it so that we might accept it at its full value. "As one doctor has said," he added, "although toxicologists and chemists have not always possessed infallible tests for practical use, it is at present a pretty certain observation that every poison leaves its mark. But then on the other hand, students of criminology have said that a skilled physician or surgeon is about the only person now capable of carrying out a really scientific murder.

      "Which is true? It seems to me, at least in the latter case, that the very nicety of the handiwork must often serve as a clue in itself. The trained hand leaves the peculiar mark characteristic of its training. No matter how shrewdly the deed is planned, the execution of it is daily becoming a more and more difficult feat, thanks to our increasing knowledge of microbiology and pathology."

      He had risen, as he finished the sentence, every eye fixed on him, as if he had been a master hypnotist.

      "Perhaps," he said, taking off the cylinder from the phonograph and placing on one which I knew was that which had lain in the library closet over night, "perhaps some of the things I have said will explain or be explained by the record on this cylinder."

      He had started the machine. So magical was the effect on the little audience that I am tempted to repeat what I had already heard, but had not myself yet been able to explain:

      "How is she to-day?"

      "Not much changed--perhaps not so well."

      "It's all right, though. That is natural. It is working well. I think you might increase the dose one tablet."

      "You're sure it is all right?"

      "Oh, positively--it has been done in Europe."

      "I hope so. It must be a boy--and an ATHERTON."

      "Never fear."

      No one moved a muscle. If there was anyone in the room guilty of playing on the feelings and the health of an unfortunate woman, that person must have had superb control of his own feelings.

      "As you know," resumed Kennedy thoughtfully, "there are and have been many theories of sex control. One of the latest, but by no means the only one, is that it can be done by use of the extracts of various glands administered to the mother. I do not know with what scientific authority it was stated, but I do know that some one has recently said that adrenalin, derived from the suprarenal glands, induces boys to develop--cholin, from the bile of the liver, girls. It makes no difference--in this case. There may have been a show of science. But it was to cover up a crime. Some one has been administering to Eugenia Atherton tablets of thyroid extract--ostensibly to aid her in fulfilling the
