Latest Findings In Science World Weight Hedudng Drugs -- Lamps for Doctors--Speed of Sap in Trees A few months ago an ovér-weight San Francisco physician tock an over- dose of dinitrophenol" and literally cooked himsell to death with the vio- lent fever generated. Thu: was at- tention attracted to a drug which makes excessive fat disappear witn- out the necessity of dieting. Five times more powerful is dini- tro?ortho-cresol, according to Drs, & C. Dodds ard J. D. Robertson who have been experimenting with it in England and who publish their con- clusions in The Lancet. Both drugs accelerate metabolism--the process whereby food is converted into energy. Such is the speeding up that the body's fat must be drawn upon to meet phy siological requirements. Hence the rapid reduction in weight. The result is much the same as when thyroid extract is administered, There is, however, this _differenca, ~When the 'thyroid glafid is sluggish, fat accentuates in what is called myxedema, the fancy name for a swelling due to infiltratior of gela- 'tinous fluid into the tissues.

Ultra-Violet rays kill germs. Be- cause of this fact it has long been the practice to treat tuberculosis of the skin and other external germ diseases by means of ultra-violet ra- diation. When it came to infections of the ear, nose, larynx, lung, the bladder, kidneys and sinuses the phy- sician was helpless so far as radiation was concerned. The lamps were too big to be pushed through. passages which were sometimes less than one- quarter of an inch in diameter. There was nothing for it but to treat inter- nal infections' with preparations, which, when irradiated by ultra-vio- let lamps, acquire remarkable healing properties. ' _ The difficulty presented by size of "lamp has been solved. It is now pos- "sible to introduce a little quartz tube an eighth of an inch in diameter and no longer than three-eights cf an inch into the ear, there to let the rays do their work of killing bacteria; or to irradiate tubercular lesions in the kidney, bladder, lung and larynx. To reach the sinuses a small purcture is made through which the miniature lamp is pushed. -e 0% Like a Miniature Sun. ~The little lamp is not unlike the tubes which glow on every Main Street and which advertise anything from a restaurant to a tooth-paste in red, blue or yellow. In the advertis- ing tube a minute quantity of gas (neon, for example, for red light) is ionized, By ionization the physicist means the partial wrecking of an atom. Deprived of an electrom, the atom. Deprived of an electron, the ("ion" means warderery2ufitil it finds an electron + take the pléce of the one it hes fost. Almost as fast as it .Aafls one it is stripped again.. Ima. gine countless billions of gas atoms thus wandering about as ions and glowing because they have lost elec- trons and we see what happens both in a glowing. advertising sign and in this little lamp. According to the now fashionable theories of the astro- physicists; the sun and countless mil- lions of stars shize because they, too, 'are composed of atoms which are stripped aud therefore glowing. What we have, then, is a miniature ultra-violet lamp, is a miniature sun which can be introduced: within the body. And the sun; as everybody knows, is the richest of all sources of ultra-violet rays, the most effective of all natural healers, - How this little sun is made to glow inside of the ear or next to a kidney is much too technical a story to be told here, It is enough to say that something like 'a miniature. radio twmiion station exci'es "the mer- cury atoms of the tube.

He wrapped a wire around the trunk of a tree and heated it, for several seconds. A little higher up he inserted an electric thermome- ter between the bark and the wood. As it rose the heated sap caused the thermometer to rise, Thus a measure of the rate of flow was provided. With this simple equipment Huber found that the flow is more rapid as the day waxes, Between 6 and 7 in the 'morning the sap in a vine moves on thirty inches in an hour; by 1 the speed is twenty-eight feet an hour; but at night thirty inches an hour is again deduced, It is clear that if sap loses heat too rapidly duving its motion the method ofs measurement fails, The critical velocity is half an inch a minute, In conifers the rate of flow is so slow that Huber cannot measure it, But in leafy trees he finds speeds as high as 150 feet an hour, 80-50) Tht Benignity of the ~ English Fields Here, something almost human looks out at you fram' the landscape, Nature here has been so long under the dominion of man, has been taken up and laid down by him so maffy times, worked over and over with his hands, fed and fattened by his til and industry, and, on the whole, has proved herself so willing 'and tract- able, that she has taken on something] of his image, and seems to radiate his presence. She is completely domesti- cated: and no doubt loves the titiva- tion%f the harrow and the plow. The fields look half conscious, and if, ever thi cattle have "great and . tranquil thoughts," as Emerson suggests they do, it must be when lying upon these lawns and meadows. I noticed "that the trees, the oaks and elms, looked like fruit-trees, or if they had felt the humanizing influences of so many generations of men, and were betgk- ing themselves from the woods to the orchard. The game is more than half tame, and one could easily understand that it had a keeper. But the look of those fields and parks went straight to my heart. Jt is not merely that they were so smooth and cultivated, but that they were so benign and maternal, so ve- dolent of cattie and sheep and of pa- tient, homely farm labor. One gets only here and there a glimpse of such in this country. I see occasionally about our farms a patch of an acre cr half acre upon which has settled this ripe and loving husbandry; a choice bit of meadow about "he barn or or- chard, or near the house, which has had some special fattening, perhaps been the site of some former garden, or barn, or homestead, or which has had the wash of some building, where the feet of children have played for generations, and the flocks and herds have been fed in winter, and where they love to lie and ruminate at night --a piece of sward thick and smooth, and full of warmth and nutriment, where the grass is greenest and fresh- est in spring, and the hay finest and thickest in summer, This is the character of the whoie of England that I saw.

On the road to Pare Jean finds a string of pearls in Buans pocket. He snatches the case from hor und the car crushes. The accident is dis- covered by Jerry Grant, whom Jean had niet. Jerry takes her back to his hostess, Helen Grant. Upon learning of Euan's disappearance' Doreen behaves in a strange manner, M. Rivaux, French in- spector, Investigdtes the case, Jean is told of Euxn's disappearance. CHAPTER VIII.-- (Cont'd.) "Good Lord," Jerry Grant groaned. "If only Rivaux were not so uttery useless," T Helen glanced at him, saw the con- cern which had never flagged sinc: the moment he had brought the girl in, and had an idea, After turning it over for a moment in her mind, she said: "Would you like to see Jean?" Laughing at the eager way he turned to her, she added: "Well, 1 think sou might see her for a while after the police have been tomorrow. It would cheer her up." Grant did not conceal his delight and promised to do his uttermost to help Jean Graham forget the tragedy of her brother's disappearance, The days passed and excepting for those intimately concerned, the van- ishing of the young Scotsman which had been such a matter of interest at the time of the accident became a thing of the past. It creemed that the case of Euan Graham would be just another added to the long list of un- solved mysteries. At the Villa Marguerite naturally this was not so, but although the thought of Euan was never far from their minds they were helpless, M. Rivaux had been up several times to interrogate Jean, because he had not been satisfied with her an- swers on his first visit, but he had thing which would help them toward | tracing the lost man, : Jean was now downstairs on a chaise 'longue on the -logia but hor recovery, which at first: had bean rapid, was slow, retarded; Helen sup- posed, by her anxiety for her brothex. This was so, but it was not all. The thought of those pearls was. worrying her into a veritable panic. The fact thabushe had not told M. Rivaux about them showed too clearly what sne feared. To say that Euan had van- ished she thought absurd. People did not vanish without a reason, and those pearls were only too. good a reason Still, how had he come by them? Had he---could he have '"taken" them? In her heart she knew that she meant stolen them, but .shrank from the word. Yet forcing herself to look the thing in the face, she acknowledged, whilst a deep flush of shame over- spread her face, that he might hove-- that she supposed he had stolen thm: else how--where--did he get them? As she became stronger she would wander off to the olive grove behind the villa to think over the horrible mystery which was engulfing her. Ske did not even care to talk it over with Helen now, for she had withheld her knowledge of the pearls and feit guilty in consequence. They would. she knew, supply a motive for her brother's disappearance, but she could not speak of them even to her friend. It would be as good as saying u.at Euan was a thief and the old instinet to shield hin 'was as strong as ever within her, % "Oh, Euan!" she sighed miserably. It seemed to her that she had failed him. Had she not put her hand in his pocket and taken out the pears the accident would never have hap. pened. J But how, when, where had he got them? repeated themselves within her unti she was nearly frantic, Meanwhile indoors Helen was sic: prised to receive a visit from Geoffrey Winton, It had been quite a while since he had been to see her, and she looked at him anxiously, Evidently something was very wrong with him, she thought, watching the restless way he moved about, " : Winton paused and peered out of the window. * "She's not about, is she?" he jerked. "D'you mean Jean? No, I think she's in the garden. What's the mat- ter, Geoffrey?" f He bit his lip, moved uncomfort- ably, then shot: "Hell!" Helen's mind immediately ran on conjugal differences, and she wonder- ed what had happened; certainly something out of the ordinary. "Sit down, why don't you, and tell me," she suggested quietly, : Winton paid no heed, but continued to move about the room, At lengtn, however, he stopped in front of her. "Helen, Doreen's pearls have been stolen," he declared. CHAPTER IX, , .

He turned and came towards her, looking so upset that she was sorry for him. "Helen," he began, sitting down vn tt arm of the sofa, "it's about thal that I've come to see you." "Oh? she wondered, "Yes, Er----well--it's devilish awk- ward," He looked apprehensively at the window again. > "Miss Grabam can't hear, can she?" "No. What is it, Geoffrey? You're very mysterious."

"Know what?" --well--that Graham stole Doreen pearls." "What? Geoffrey, really!"

'They may have been stolen since then." He shook his head slowly. . . "Everything points to it. I'm afraid Suzanne swears that the case has been empty since that day and Doreen con- fesses to having left them on hev dressing table. She often does .eave things about all. night. Suzanne said nothing, because she thought that Doreen had sent them to have the clasp mended---she had been going to do so, it seems; and Doreen thougat that the maid had put them away." Helen felt stunned and stared in- credulously before her, whilst Winton added: "We may be wrong, mind you, only I'm afraid the police will catch on to it. I--I thought you would like *0 know." : It was Helen who now moved rest- lessly about the room. This sugges- tion of Geoffrey's was vile, monstrous, and yet she found herself uncertain about it. She glanced at the man sit- ting hunched up in the corner of the soft, and sudaenly felt sorry for him. "It's horrible for you, Geoffrey," she said; 'then trying to be consoling, she added: "Anyhow, you'll get the insurance money, which is something." To her amazement, he leaped to-his feet and banged his fist on the tab'e. "But I won't; I won't," he almost sobbed. fl : Helen gasped. - : "Why, what do you mean?"

In a moment or two, Helen stoud at the window, watching Winton di 'away. Now --how was she to i Jean? The thought appalied- her. By CHAPTER X. Helen as rot surprised: when short- ly M. Rivaux presented himself at her. villa and asked for Jean, He was in a state of high satisfaction and regarded Helen from gloating eyes. "So. now we. find our motive," he ejaculated. Helen's heart sank, but she asked steadily: : "What do you mean, M. Rivaux?" "Where is Mademoiselle?" Glancing through the window, Helen said: "She's ust coming across the gar- den." As she spoke Jean appeared, fol: lowed by Grant. Both were smiling and the young man's arm was about the girl--just to help her up the steps, he explained hastily. "I've been sitting in the olive grove," Jean volunteéred, omitting to mention, however, that Grant had found her there in tears and had stay- ed to console her." But suddenly; her light, Jean discovered Rivaux, who was watching her intently. "Oh, I hadn't seen you," she apologizol. "What is it? Is there any news?" A smile oozed out of Rivaux., "News?" he said, carelessly shrug- ging his shoulders. '/There is always news, There 18; for example, the news that the pearls of Mme.

This was the greeting I received from my eight-year-old niece when! met her for the first time, upon my arrival for a visit with my sister in New England. During the ten years I had spent as a kindergarten teacher on the Pacific coast, I had anticipated seeing the little girl who had come in- to my sister's home, Before my bag was 'deposited, she began trying to open it, saying again, in a commanding way, "Tell me what you brought me. Didn't you bring me anything? What did you come for, it you didn't bring something for me?" * The mother apologized, "Of course Joan is glad to see you, but she expects you have brought-her something pret ty from the coast." Surely "had not forgotten to bring my only niece a gift. = In fact, I had many in the trunk yet .to come, and had -been-loeking- forward to the plea sure of giving pretty things, Books and trinkets, to my sister's child, How: ever, -the situation became less and less pleasing. Joan continued teasing and hinting for specific things. I took from the hand-bag a choice illustrated book for children, Seeing the disap- proval on her face when 1 passed her the hook, I felt uncomortable, and was about to explain that I had other gifts in my trunk, when she broke out, "Is that all you brought me? I don't want that old book," and threw it aside. Running to her mother, she cried, "Auntie didn't bring me anything but an old book." rs : To my surprise her mothgr patted the child and told her not to cry, of course Auntie had other lovely things for her which she would get later. I was deeply concerned by the child's conduct and my sister's atti. tude.
