Theprogram consisted of the following addresses. "A Review of the Progress Made in the

Chemistry of Physiology and Yutrition." by R. K. Flege of the University of Kentucky. "Progress in Chemical Education." by Professor V. F. Payne of TransvlvaniaColle~e. . The Cincinnati Section, A. C. S. The 186th regular meeting of the Cincinnati Section of the American Chemical Society was held in the main auditorium of McMicken Hall, University of Cincinnati, Wednesday evening, December 8th. The address of the evening was given by Dr. Glenn E. Matthews of the Eastman Kodak Co., Rochester, New 'York. His subject was "Color Photography" and the lecture consisted of a discussion of the basic principles of absorption and reflection of light, a description of color filters, and a review of the principal processes of color photography and color motion pictures. The lecture was illustrated by charts, autochrome slides, and a reel of colored moving pictures.

Makes Water-Proof M i l Glue. Ordinary animal glue can now be waterproofed and made to last as long as the best casein glues on the market. Dr. Frederick L. Browne and Clarence E. Hruhesky of the U. S. Forests Products Laboratory a t Madison, Wis., disclosed their discovery a t the meeting of the American Chemical Society in Philadelphia. Although animal glue can he made water-resisting by the use of common formaldehyde the fact cannot be made use of in the woodworking industry because the rraction takes place so quickly that the glue so treated hardens before it can be applied to the surfaces to be joined. Dr. Browne said. But if a compound of formaldehyde is used instead, a suficient amount of slowly acting formaldehyde can he introduced in that way to render the d u e water-oroof and still kern it fluid l o w - enouah - to he used conveniently in the glue rooms of furniture factories. The working life of the glue can also be inneaged bvaddiismallamounts of eertam acids, Dr. Browne said. he animal glue is then juscas good for woodworking a s the more expensive glues made from casein.-Scicncc Sem'ce Research Ten Times More Costly Then Publication. Between thirty and forty cents a word is about what it costs on the average to conduct the chemical research reported in two leading American chemical journals. About three cents a word is the cost of publishing the articles announcing the researches. The authors contribute their articles free to the journals and the public and posterity are the beneficiaries of the new knowledge added to the world. These figures are announced in the scientific journal, Science, as a result of a survey conducted by Prof. W. A. Noyes of the University of Illinois, to determine the relative cost of research and publication of results. Research necessary to produce one article amounted to $5 a word, and the scientific work behind - soine articles cost m a y thousands of dollars.-Science Service
