Ki 2 v GOODWIN'S WEEKLY . Wj Science and Industry's Progress HI a remarkable operation has- Tjecm Hi I ir Performed wtn 'great success Hi ' on an imbecile Child by Prof. Hi Erwin Payr, director of the surgical Hj clinic attached to the Leipsic unlver- H slty The professor planted a piece of HI the thyroid gland taken from a heal- HI thy child born of a healthy mother in- H to the liver of an imbecile child Who HI immediately afterward began to f im- Hi prove in intelligence, which steadily Hi increased until a complete cure was Hf effected and the patient was discharged Hj from the clinic. H The inference that snails can see Hj has been drawn from opposite observa- H tions some results indicating an H avoidance of light, while others seem B to show a preference for light. In a H more thorough investigation of Helix H pomatla, the vineyard snail, Prof.r H Emilo Yung of Geneva has now proved. H that their eyes arli absolutely slgbt- H less. With 17G specimens he made fl more than 2,000 observations, and in Vfl no case was there the slightest ovi- 2fl dence of the perception of light or dark B paces, and obstacles were entirely un- fl perceived. H m Statistics collected by Borelly, the H French astronomer, Bhow that since R the sixteenth century 376 comets have HP been discovered, of which IOC were HI periodic and 19 have been seen at H more than one return, and 56 have M been visible to the naked eye, with. 7 m that could be '.seen in full daylight. H Nearly two-thirds of the discoveries H appear to have been made in morning H before sunrise, more than half in the H second half of the year. The French H observatories have led in discoveries, H sixty seven of the comets having been H first detected at Marseilles and forty- H six at Paris, but only sixteen at Gen- H eva, which has the next highest rec- H ord, fifteen at Florence, and fourteen H at the Etak observatory. H H A British engineer has patented an H apparatus which, it Ib claimed, will H prevent the clouds of diut raising in KM dry weather by automobiles and other H vehicles. The device, which is simple H and inexpensive, collects the dust as H it rises. The dust Is drawn into con- H duits, which are funnel shaped at the H mouth, and which run from the rear of H the front wheels to the rear of the H back wheels. These conduit3 are con H nected with a box, Into which the dust H Is driven by the pressure of air, or H this end can also be accomplished by H the aid of a centrifugal fan geared to H the driving shaft of the automobile. H The contents of the dust box can be H discharged by pulling a lever at the H front of the vehicle. ' H It has just been computed that the H day fly lives 24 hours, the May fly 6 H weeks, the butterfly 2 month3, as alas, H also does the flea; the fly 3 to 4 H months; the ant, the cricket, and the IH bee, 1 year each; the hare, Bheep, 6 to H 10 years each; the nightingale, 12 H years, the wolf, 12 to 15 joais; the H canary bhd, 15 to 20 years; the dog, H 15 to 25 years; cattle, 25 years, the horse, 2WUp 30 years; the eagic, 30 yoars; theStag, 35 to 40 years; heron, lion, and bear, 50 years each; tho raven, 80 years; elephant, turtle, par rot, pike, and caip, 100r years each. The ivy outlines 200 years ;the elm, 300 to 350 yfcars; the linden, 500 to 1,000 years; ihe locust tree and the oak, 400 years; the fir, 700 to 1200 years; tho palm trees, 3,000 to 5,000 years. A new copper alloy which has the hardness of steel and has great te'nslle strength has been invented by a French metallurgist. Eleven pounds of chromium are melted for one hour with eleven pounds of aluminum, and then 242 pounds of copper are added. The entire charge is kept at fusing temperature for half an hour. Then fifty-five pounds of nickel are added and the mixture is heated another hour, upon which forty-four pounds of zinc are added. The proportions of copper and chromium can be varied ac cording to the use to which the alloy ,. is to be put, but the order in which the metals are brought to melting tem perature, as also the addition of alumi num, must not be changed. Capetown dispatches says that the latest -thing in the sartorial imo is trousers for oxen. This method of clothing beasts of burden is not due to any accession of style in South Africa, but the garments have become a necessity to protect the animals from the tsetse flies, which are a tor ment and often a fatal enemy. The tsetse flies swarm about sunset, travel ing near the ground, and they have been known to poison entire herds of cattle. Mr. Ox receives a bath before he dons his habiliments of civilization. This bath consists of oil and resin, and i3 supposed to free the animal of all ticks and parasites. His "pants" are then thoroughly soaked in oil and aesln, and when the swarms of flies come In contact with the trousers legs they die by the thousands. Horticulturists have for some time been experimenting on the effects to be obtained by subjecting plants to the vapor of ether, chloroform, and other volatile substances They have found that the growth of many fruits and flowers can be forced by this method and have obtained particularly strik ing results with lilacs, which they have thus been able readily to obtain in winter. An American agriculturist has experimented more particularly In the effect cf these and other sub stances on the ripening of fruit. His observations have shown that in the majority of cases the more volatile the substance to which the plant is treated, the more rapid 1b the ripen ing. In foicing the ripening of dates, for instance, he found that the best results were obtained when he em ployed soetic, propionic, lactic, or sail cylic acid Heat powerfully stimulates . the ripening process and one of the peculiarities of fiuits thus rot cod to matuiity is that they are generally found to keep bettor than th030 which have ripened naturally. 1 v $ If your last month's grocery bill was I $40 you would have received a r four per cent cash ; dividend, or $ 1 .60, had you been a -j subscriber to the Community Sav ings Plan. . : other bills in pro- I ! 8 - portion. at any "four per' cent store. make the money -: you spend pay dividends. j COMMUNITY T SAVINGS COMPANY y INCORPORATED J Z?
