Ever since Schimmel & Company in 159P distilled the several parts of Cinnumomurn Cassia Blume, the cassia oil situation has beeen pretty well understood. In connection with the study of Chinese medicinal plants and drugs undertaken in this laboratory, it seemed desirable to learn more about these oils particularly since it became possible to obtain larger amounts of material directly from China. It was for this reason that the experiments here recorded were undertaken. In so far as the leaves and twigs were distilled separately, the results supplement those given by Schimmel & Company. BALES OF CASSIA LEAVES A N D TWIGS. The leaves were kept compact by bamboo splits (Bambusa, Chinese TsO), with four bamboo stkks on the four sides. The twigs were similarly bound but required no bamboo sticks. The bales were wrapped in mats made of Liw'stoma chinensis Br. (Chinese, Boo Pao) and tied with rattan, a species of Calamus (Chinese Dun). Source and Description of Material.-Upon the suggestion of Dr. Paul Reinsch, late Ambassador of the United States of -4merica to China, the materials used in this investigation were kindly imported from China by Anderson, Meyer & Co. of New York City. They consisted of five bales of about 100 pounds each: three of leaves and two of twigs, which are shown in the accompanying photo-The weights of the individual bales, of their contents, etc., are herewith tabu-graph. lated.
