The author also emphasizes precautions against infection. He points out the advantages of human milk, but maintains that this ideal food does not entirely meet the requirements of premature babies. He uses supplemental, synthetic substances, salts, and proteins. For many years he has followed Hess’ schedule of feeding as used at the Sarah Morris Premature Infant Station. J. P. GREENHILL.

The authors present a short review of the current literature on calcification of the placenta. In addition, they present an instance of two successive pregnancies in the same patient where marked calcification was present in both placentas, In the first pregnancy the mother fell into labor normally at term and was delivered by outlet low forceps of a stillborn infant. ,No cause for the stillbirth could be determined, but there was marked calcification of the maternal plate of the placenta and of the villous tree, especially around the periphery. The authors felt that the extensive calcification of the placenta might have been responsible for the fetal exitus, and therefore in the mother’s next pregnancy a cesarean section was performed in the thirty-eighth week. This time a living baby was obtained, and the placenta showed pathologic changes similar to the first placenta. In both pregnancies the blood chemistry in regard to serum calcium, acid and alkaline phosphatase, and plasma phosphates was normal. There are three microphotographs of these placentas and two gross photographs showing the location of the calcification. L. M. HELLMAN.

In 63 cases of threatened or actual premature labor, 20 of the patients gave a history These patients of previous abortions or “other abnormal terminations” of pregnancy. were treated with vitamin E, and 46 living infants were delivered, a salvage of 73 per cent. In the patients in this group who had a blood estrogen determination made, 87 per cent showed a high estrogen level early in pregnancy. Combining the results reported in this series with a previous series in which vitamin E was used in the treatment of threatened premature labor, there were 92 normal living children born to 109 patients. In the entire series there only one of which (with a cleft palate) lived more than were only six malformed children, three months. If vitamin E is used in the treatment of threatened abortion or premature labor, a product of proved potency must be employed in adequate dosage. Dosage must be determined in each case, depending upon the severity of the symptoms and their duration. The authors are of the opinion that routine Treatment must be continued until term. determinations of blood estrogen should be done on pregnant women when they first report for antenatal care. In this way prophylactic treatment with vitamin E can be given when The patient is instructed to report if any slight indicated by a high blood estrogen level. abnormal symptom develops, such as an area of uterine tenderness, sacral backache, or spotting of blood, when the dosage of vitamin E can be increased.

The author reports 182 pregnancy tests using clawed toads (Hogben’s test); according to the results obtained there were only 3 per cent incontestable erroneous results. A positive reaction is considered a reliable sign of an undisturbed pregnancy. In comparison with the Asehheim-Zondek reaction, the simpler technique of the frog test and the short reJ. P. GREENHILL. action time required for the test are an improvement.
