GENERAL The Recent Change of Att;tude t3ward the Law of Calse and Eflect. P. W. BRIDDMAN.Science, 73, 5 3 W 7 (May 22, 1931j.-"It is now becoming common knowledge that one of the most startling developments of the altogether surprising prozrxs ol physics in the last few years has been a weakening of the belief of thc physicist, a t least, in the validity of thc causality principle. I want to examine with you this situation-to enquire in what sense we are losing our conviction of the validity of the c a u d i t y principle, and to discover some of the implications. I want especially to emphasize that I am concerned only with the objective aspects of the situation. The idea oi eausality which we shall discuss is as remote as possible from thc subjective questions of free will or determinism which are often associated with it, both in popular discussions and in a number of recent more technical discussions hy scientific men. We shall be concerned only with the domain accessible to enpcriment, and the causality principle, in the sense in which I use the term, is a principle dealing with the findings of actual experiment." This, an introductory paragraph from the address delivered a t the University of WisG. H. W. consin, April 21, 1931, gives the purpose of the paper. Heralds 6f Progrdss. J. C . K a ~ ~ r aAm. . J . Pharm., 103, 218-37 (Apr., 1931) This is an address delivered a t Founder's Day Exercises of the Philadelphia Collegc of Pharmacy and Science, but it is an appeal for investigators and pure research in thc fields of science. Chemistry, physics, and biology have all served humanity because 01 the courageous spirit of the research worker. The achievements of the men who have left us a "goodly heritage" is the challenge of the speaker. G. 0. A New Eoa of Wonders. W. S. DUTTON. Americnn. 91, 22-3 (May, 1931)"A peer into the future," according to the author, reveals: "the evolution of modern radio rcception into a home theater, vitamized food as a substitute for less sunlight, glass skyscrapers, and frost-proof, non-skid self-illuminated highway construction materials" These prophets of the new industrial order span thirty to forty years in their plan.$ for the future of their industries. That thcse seers are taken seriously by Americnn industry is testified in the $200,000,000 spent annually upon research. Thus do they B.

Intelligence Tests Criticized by Psychologist. Thc clinical use of the so-called intelligence tests should he rcgarded as an a r t and not a science, since the results are not sufficiently enact to be truly scientific, according to Blanche M. Minogue, psycho lo^ gist a t Letchwcrth Village, Thiclls, New York. "Intelligence itself wc do not understand and cannot measure," she says. Miss Minoguc recommends a combination of tests showing ability t o understand verbal abstractions, performance and achievement tests, and tests for special abilities and disabilities ~ h c dctcrmininga n child's mental grade and general ability. She recommmds also that emphasis be plat-d on thz study of th- h i g h s grade defectives, since most can be hoped for from training and guidance of thcse individuals-Scicnce Serrice
