We need to educate the medical profession at large as well as the public on the extreme value of postmortem examinations. These examinations . . . would help us at every step of our work and do more to advance our profession than any other one thing.—Journal of the Kansas Medical Society.

A Useful Discovery.—For 40 years physicists have been seeking some substance to serve as a screen, cutting off all the light and heat-giving rays of the spectrum, while allowing the invisible ultra-violet rays to pass. Finally, Prof. R. W. Wood of the Johns Hopkins University, has discovered the long-sought substance, which bears the name of nitrosodimethylanilin. When combined with cobalt glass, this substance furnishes a screen which allows only ultra-violet rays to pass through. The discovery is of importance for some difficult scientific investigations.—Carolina Med. Jour.
