Abstract
THE veteran limnologist, Dr. E. A. Birge, together with Dr. Chancey Juday and other collaborators, has made several additions to the detailed study of Wisconsin lakes in the Transactions of the Wisconsin Academy, vol. 23, Proceedings of the American Philosophical Society, vol. 66, and in Ecology, vol. 8. The Academy papers deal with the temperature of the bottom deposits of Lake Mendota, with the chemical composition of its larger aquatic plants and with the phosphorus content of that and other Wisconsin lakes. Temperatures were measured in the rmid of Lake Mendota down to 5 metres, in depths of water from 8 m. to 23.5 m. The data accumulated are used to calculate the annual heat-budget. At the shallowest station this amounted to 2950 calories per sq. cm. and 1100 calories at the deepest. Preliminary data on the heat-budget of Karluk Lake, Alaska, are given in Ecology, July 1927. These are compared with the values given by lakes in Central Europe.
