Comparative tests on nonpregnant women of the same age revealed that the ocular tension of pregnant, parturient, and puerperal women is usually reduced. In 27 women in whom the values had been found definitely reduced during pregnancy, the author renewed the test one or two years after delivery. The presented tabulation clearly demonstrates that the ocular tension of the same person is usually lower during the processes of gestation than is the case one or two years after delivery. Discussing the possible cause of the ocular hypotension during pregnancy, the author suggests first that the acidosis of pregnancy might play a part, pointing out that a lowered ocular tension has been observed during other processes that are accompanied by acidosis, such as diabetic coma. Other factors that might be involved are reduction in the osmotic pressure, chemical changes in the blood, or changes in the endocrine function. A complete explanation has not been found as yet. J.

The hemoglobin, the bactericidal power of the blood against hemolytic streptococci, and the calcium, inorganic phosphorus, and phosphatase zontents of the serum were studied in 101 women at the seventh month of pregnancy. Seven per cent were found to be definitely anemic and 19 per cent probably slightly so. In 39 per cent, the calcium level was less than 9 mg. per 100 ml., which The product calcium x phosphorus was 25 on the is believed to be abnormally low. The blood of 22 patients failed to inhibit the growth of streptococci and, average. of these, one developed pyrexia during the puerperium; fever also occurred in a patient whose blood inhibited growth at the seventh month.
