turn green in the presence of a highly polished one. The boiling point for some varieties is quite low, while others are likely to freeze a t any moment. All varieties melt under proper treatment. The taste varies from sweet to very bitter depending upon environment and treatment. Chemical Properties: Absorbs, without dissolving in, a number of liquids, the activity being greatly increased by alcohol. Absorbs seemingly unlimited quantities of expensive foods. Some varieties catalyze this food into fat in accordance with the formula: PV = RT. Many naturally occurring varieties of Wo are highly magnetic; in general the magnetism varies inversely with the density and size, directly with the square of the valence, and inversely with the cube of the age. Some varieties tend to form Anne-ions; others cat-ions. Their ionic migrations vary widely. All varieties exhibit great affinity for Ag, Au, and P t and for precious stones in both chain and ring structures. The valence toward these substances is high and its study is complicated by the fact that the residual valence is never satisfied. Many stable and unstable unions have been described-the latter in the daily press. Some varieties, being highly explosive, are exceedingly dangerous in inexperienced hands. In general, they tend to explode spontaneously when left alone temporarily by man. The application of pressure to different specimens of Wo produces such a variety of results as t o defy the Principle of LeChatelier. Uses: Highly ornamental. Wide application in the arts and domestic sciences. Acts as a positive or negative catalyst in the production of fever, as the case may be. Useful as a tonic in the alleviation of sickness, low spirits, etc. Efficient as a cleaning agent. Equalizes the distribution of wealth. Is probably the most powerful (income) reducing agent known." G. M. C.: "Splendid! Marvelous! Wonderful! Altotuses, congratulate your new brothers in HOH." Altotwes: (Running forward to shake hands with the new brothers) "Brothers!" (CURTAIN)
Cod-Liver Oil Helps Tuberculous Children. A regular regimen of cod-liver oil is helpful to underweight school children suspected of being incipient or arrested tuberculous cases, according to Dr. Arthur D. Holmes of Stoneham, Mass., who spoke hefore the recent meeting of the American Chemical Society. With Miss Hanna I,. Ackerman and Miss Madeleine G . Pigott, he conducted tests on a group of school children from tuberculous surroundings. At the end of the investigations, the records showed a definite increase in body weight and a lowering of abnormal temperatures. There was also an improvement in general health and in quality of school work.-Science Sm'ce
