WE have received the first five numbers of the first volume of a new Russian journal, devoted to biochemistry. It is entitled Biochimia, and is edited by A. N. Bach and W. A. Engelhardt. The papers are in Russian, but each is provided with a summary in English or German. The average size of each number is about 120 pages. The papers deal with work on vitamins, enzymes and other biochemical problems. The journal should enable workers in other countries to gain some idea of the work which is being carried out in Russia in biochemistry.
