Kansas University Weekly. 159 Chemistry Notes. The Chemistry department has purchased a new acid pump for drawing acids from their carboys and also a cylinder of liquid anhydrous ammonia to be used in a special investigation. Prof. Bailey has an article in the October number of the Bulletin of Pharmacy on preservatives in food. While he does not entirely condemn their use, he says that any substance which will prevent decomposition and fermentation in the foods will retard the action of the digestive ferments and must tend to produce indigestion. At the Chemical Seminary last Monday Prof. Bailey and Mr. Whitten gave reviews of recent articles of interest to chemists. University Photo Engraving. Last spring Prof. Stevens conceived the idea of making half-tones for use in the various publications of the University. He at once procured the necessary apparatus and began a series of careful experiments which kept him busily occupied during the summer vacation. The main difficulty which he encountered was the lack of any definite description of the methods to be employed, as all the works so far printed on the subject of photo-engraving are more practical than scientific. He has, however, succeeded to an extent, that is very encouraging. This work will be of great value to the University in providing illustrations quickly and at actual cost. Since the beginning of school the work has been turned over to Mr. F. E. Marcy who has made several excellent half-tones, including the one in this number of the WEEKLY. D. D. Gear, who has been playing base ball during the past season, has returned to the University. He pitched for the Fort Worth team, in the Texas league, until that league disbanded, when he was signed by the Cleveland National league team and finished the season with them. He was worked very little by the Cleveland management, but showed up remarkably well and will be pushed forward next season. Mr. J. H. Engle, writing from Hoxie, Kansas enclosed the following extract from a private letter received from Mr. Fred M. Raymond'96 who as the readers of the WEEKLY know,is continuing his studies in English at Columbia. "My first lecture as a Ph. D. in embryo was taken this morning from Dr. Woodbury in the Pre-Aristotle conditions leading to Aristotle's Poetic. I am well introduced and cordially received here among literary and business men. Last night I reported after-dinner speeches of Mayor Strong, and Messers Roosevelt, Lauterbach and others. A week or so ago Mr. Barteaux and I heard Dr. Parkhurst's already famous anti-Bryan sermon. Last Sunday we heard Madison Peters, and next Sunday will probably hear Rev. Dr. Savage, successor to Robt. Collier. I have met many interesting persons, not the least of whom are Mr. Barteaux who took me right under his wing, Mr. Burnett, Miss Kate Stephens who is well known here, Miss Gertrude Hunnicut and the two Gleeds. Eugene Caldwell is working for the N. Y. Telephone Co.; Albert Fullerton is in the Columbia Law School. Chas. Johnson is attending physician in one of the hospitals. Let us say a word about WEAVER'S Cloaks and at the same time we'll tell you that a minutes peep is better than a column of description. Nothing in the coat line has a place in the store but what are known to be good. None but respectable manufacturers can tempt Weaver and when you spend a dollar with him you get a hundred cents, worth of certainty—the certainty that what you buy is the best of its kind and if he made a mistake in buying, will pay for the error. You get the best, pay the least and are at absolutely no risk in buying your wraps at WEAVER'S.
