The Chemist and Druggist announces that an important discovery in medical chemistry has recently been made by Professor Anschutz, of Bonn. After many trials, that chemist has succeeded in combining chloroform with the anhydrides of salicylic and cresotinic acids so as to produce solid and portable substances, from which pure chloroform can readily be derived. These solid chloroforms are simple mixtures and only about twenty-four hours are necessary for the process of cystallization to take place, which process is a means of essential purification since any impurities that exist are left out as the crystals gradually separate. These compounds are not decomposed by light, as is the case with pure unalcoholized chloroform, and therefore the new compounds will probably play an important part in the anæsthesia of the future. The readiness with which they can be produced is another signal advantage in their favor. The questions of storage and transportation,
