REVIEWS AND ABSTRACTS
In the discussion of this paper, Cathala reported a case of twins which had very dissimilar ossification centers, yet he ruled out superfetation because histologic examination of the placentas showed them to be of the same age. Furthermore, in some cases of uniovular twins where there is no doubt that both fetuses :ue of the same age, there way be fouJl(l ossification centers which are not equally deye]operl. J. P.

The point of ossification in the inferior epiphysis of the knee joint appears about the ninth month of fetal life. It is always present in a child born at about term. At term it measures 4 to 6 mm. in diameter. The point of ossification of the superior epiphysis of the tibia appears at eight and one-half months, is not always present in the newborn at term and varies from 1 to 3 mm. in diameter. There is a constant relation between the length of the body and the ocenrrence of the points of ossification and a similar relation, but less marked, between the weig"\lt of the child and the degree of ossification. Every newborn who does not present a point of ossification in the region of the knee, weighing less than 2,000 grams and shorter than 44 em., has not yet reached the beginning of the ninth month.

Fujinkwa Gakkwai Zassi, 1926, ix, 28. A semisolid mass was made with barium sulphate which was injected into the uterus of 80 healthy puerperae between second and thirty-fifth day postpartum. Roentgen :films were made in dorsal and lateral positions in intervals. The follow· ing observations were made in these studies: Even thirty days after labor the uterine cavity had not narrowed to its normal lumen but still showed moderate dilation. As compared with the multipara, the cervical canal of the primipara contracted much slower, and even late in the puerperium it was still seen dilated. When cervix and uterine cavity were studied together in the films taken in these two directions, in many cases a rotation could be noticed, to right or left, of uterine body against cervix, outside of changes in anteversion or retroversion. In later periods of the puerperium retroversions were seen more often leading to the con· elusion that secondary retroversion develops in the course of the puerperium. AUTHOR'S ABSTRACT.
Biermer, L.: X-Ray Treatment for Ptyalism of Pregnancy. Medizinische Klinik, 1924, xx, 243. It is well known that after x-ray treatment, especially in the region of the head, many patients complain of marked dryness of the mouth which persists for some time. This observation led Biermer to use the x-ray in an attempt to check temporarily the function of the salivary glands in a patient with ptyalism of pregnancy. Before treatment with the x-ray the average :fluid intake by the patient was between 1100 and 1300 c.c. The daily urinary output was between 350 and 850 c.e., while the amount of saliva varied from 550 to 800 c.c. daily. The latter figures, though large, do not represent the actual salivary output, for most of the saliva was swallowed. Psychotherapy and atropin were of. no avail so x·ray was used. The parotid glands received the most intensive and the sublingual glands the least intensive radiation. There was a very rapid subsidence of the salivation and the patient went to term without any complications. .J. P. Ga.EENHILL.
