Methods used for the first time in the study of the Foraminifera are yielding results that are of interest to students of biology and geology by establishing the rate of reproduction, the probable rate at which the tests are contributed to the sediments, and the rate of sedimentation in the sea. Statistical studies are being made from samples taken with a special dredge, the population per unit area from samples obtained with a new type of suction grab, and core samples are used to determine the vertical distribution of tests in the sediments.
