The folowing notes on the work of the Arctic Institute at Leningrad have been received from Professor R. Samoilovitch.

The size of the territory of the northern part of the U.S.S.R., the different characteristics of its natural wealth, its climatic peculiarities, its economic usages, the difficult approach of many of its districts, and, finally, the almost complete absence of means of communication, together with the specific navigation conditions of the waters that wash it—all these involve the use of special methods for studying the European and Asiatic parts of the Soviet Arctic.
