A CORRECTION Mr. Neil E. Gordon, Journal of Chemical Education, College Park, Md. Dear S ir: We wish to call your attention to the glaring error on page 1087 of the September issue of your JOURNAL, in the abstract of an article by Dr. Alfred F. Hess which appeared in the July 30th number of the Journal of the American Medical Association. In the third paragraph you say, "The specific activity of the milk is maintained for a period of at least six weeks." Dr. Hess, in the conclusions of his article, says the specific activity of the milk is maintained for a period of at least six month. You will well realize that a period of but six weeks would make the commercial possibilities of such a product improbable, whereas a period of at least six months makes them probable. Our research laboratory, under the direction of Dr. G. C. Supplee, has been cooperating with Dr. Hess for over two years in the irradiation of dry milk. Our researches have shown that the activity of the milk is probably maintained indefinitely. Yours very truly, The Dry Milk Co., I,. J. Auerbacher, V. P & Mgr. Dryco Dept.

Emerson Was Interested in Development of Chemistry. Ralph Waldo Emerson, the great essayist, kept in close touch with the development of chemistry from the time he was a boy of seventeen until his old age, Dr. Charles Albert Browne told members of the American Chemical Society. Emerson's journals and essays are filled with chemical references, said Dr. Browne, while he drew freely upon his knowledge of this science for many of his most striking analogies and comparisons.-Science Serdcc
