ATTEMPT TO STANDARDIZE CHEMICAL SPEECH Most of us mispronounce a good many chemical words. Dictionaries do not always agree and teachers of chemistry as well as others, even if they attempt t o be careful in their pronunciations (many do not), have reason t o feel confused. The confusion of t h r student is apt t o be even greater; he may not even he sure a t first that his teacher who says i o d i n e and s 6 I' il t e is referring t o the same thing as his teacher who says i o d i n e and s o' l o o t . The Nomenclature, Spelling, and Pronunciation Committee of the American Chemical Society is seeking t o determine usage for some of the commoner chemical words and hopes t o set up some standards. Wide coiiperation is going to be necessary. The Committee is fortunate in having the help of C. A. Jacobson, whose "Pronouncing Chemical Formula Speller" is well known, that of Austin M. Patterson, whose dictionary work has been extensive, and that of an expert phonetician. Many chemists are t o be asked t o check a list of some three hundred words for preferred pronunciations. The Committee will be glad t o hear from chemists interested in this subject. A complete report will be offered for publication. The Ohio State University, E. J. CRANE, C h i r m a n Columbus, Ohio
Announcing "Science Education." The General Science Quarterly, published for twelve years by Professor W. D. Whitman of Salem Normal School, Salem, Mnssachusetts, has become the official organ of the National Association for Research in Science Teaching. I t will, hereafter, be published under the title Science Education, and will devote its pages t o the teaching of science in all grades from the kindergarten t o college. The first issue under the new name appeared in June, 1929. A sample copy of this issue may be obtained by writing t o Science Education. Salem, Massachusetts. The journal is being edited by a committee of the National Association, composed of Walter D. Whitman, Salem Normal School; Earl R. Glenn, Montclair State Teachers' College: Charles J.

A CORRECTION In the article "Insects and Chemistry" by Willem Rudolfs, which appeared in the June issue of THISJ O U R NA L , the upper legend of the illustration on page 1104 is incorrect. I t should read: " Upper: larvae have burst through the skin and have spun their cocoons on top of the caterpillar."
