 SCIENTIFIC MISCELLANY.


 SCIENTIFIC MISCELLANY. The fermentation ot malt liquors has been found to turn 25. COG. 900 900 gallons of carbonic acid yearly into the atmosphere of Great Britain.
 Crookes has found that the presence of one part of samaritan affects the spectrum of 500 900 parts of calcium, so great is the delicacy of spectrum analysis.
 The Milan Society of Hygiene has made the singular suggestion that the soil of cholera infected districts may adhere to shoes, and give rise to the disease in new localities to which it is thus conveyed.
 Italian officers are being taught how to collect and preserve specimens of marine animals and it is expected that the navy will thus be enabled to make scientific collections of great value from various parts of the world.
 A French investigator, Wi,z, believes he has discovered an antagonsm between ozone and cholera, the proportion of the for mer in the atmosphere of Paris last year hav- ing been in inverse ratio to the mortality from the disease.
 Not only may the amputated parts of certain low organisms be re grown, but the pieces removed may themselves become com plete animals. Gruber, in Germany, has suc- ceeded in dividing and re dividing infusoria until sixteen perfect individuals were pro- duced from the original subject.
 p,aaDc o{l ically recording the exact amount of energy stored in electric accumulators, or storage batteries, has been discovered by Crova and Garbe, French electricians. They claim that they can also ascertain the quantity of cleo tricity still held in reserve at any given mo- ment
 Biniodide of mercury, according to Miguel, is the most powerful antiseptc known, solution of one forty ,thousandth strength rendering life impossible to any form of microoe or germ. odide of silver is next in destructive power, and bichloride of mercury requires strength of one fourteen thousandth
 Comparing modern gigantic animals with the fossil remains of the great creatures which lived in earlier geological ages, MT. R. A. Proctor concludes that it may we'll be doubted whether at any time in the past his- tory of the earth the average size of the ten largest creatures by sea and land exceeded the average size of the ten largest species now existing.
 According to Ptolemy, the first eclipse recorded-one of the moon-took place March I9th. 72I B. C., al $40 p. m., and was accuratei, observed at Babylon. The Egyp- tians claimed to have observed 373 eclipses of the sun and 832 of the moon in the period from Vulcan to alexander. who died in 7a3 B. C. The theory of eclipses is said to have been known in China before I2o 8. C.
 The dome to contain the 3o.,nch tele. scope of the new Bischoffsheim observatory at Nice is the largest revolving dome in the world, having an internal diameter of "a Ia feet and a weight of nearly o4 tons. Ye, the great structure can be easily turned com pletely around by small wheel in four min utes. It floats in trough rim containing non-freezins solution of chloride of magne- sium.
 Progress of Medical Science.-Physic appears to have been practiced first by the Egyptian priests. Pythagoras endeavored to explain the philosophy of disease aad the actien of medicine about sao B. .. Hippo crates, the father of medicine, fiourished about 42a 3. C., and Galen, born r3r A. D., was the oracle of medicinal science. About 9so, Avicenna, Arab, wrote a system of medicine. The dogmatic age of medicine ' lasted until the reformation. when it was at- tackled by Paracelsus and Vesalius early in the sixteenth century. An entirely new sys- tenn of physiological and pathological spec. ulation was furnished in 1928 by pr. Harveys discovery of the circulation of the blood: and since 1890 medical practice has been transformed by physiological and chemical research. The past decade has given us the beginning of new epoch-thai of the development of the germ theory of disease-in which science is called upon to defend our bodies from the mieroscopic par- asites which prey upon them and produce our most dEeaded ailments.
