本文对白化病大鼠绒毛尿囊胎盘的发育进行了组织学和细胞学研究。这些发现与Duval（1891）的几个重要观点相矛盾，并部分证实了Jenkinson（'' 02）。研究了前一篇论文（Bridgman，'' 48）中描述的子宫。将其他植入部位固定在Champy液中以显示线粒体和高尔基体。线粒体染色显示巨细胞内有特殊的长纤维。线粒体似乎比以前描述的要长，除了在线粒体合胞体中，它们在胎儿血管边缘沿着的脂肪滴之间呈微小颗粒状。滋养层的高尔基体物质以前没有被描述过。在巨细胞和其他大型滋养层细胞中，它在细胞核周围形成一个或多个网状结构。在胎盘合胞体中，它由与母体血窦相邻的短杆状细胞组成。这种配置的可能意义，结合合胞体线粒体和脂肪的分布，进行了讨论。讨论了糖原摄取和分布的问题。最有争议的观察结果是，结合区的糖原细胞是胎儿起源的，代表原始的胎盘外细胞;有一个胎儿血管内的"疟原虫"，它迁移到母体动脉子宫内膜的结合区。还表明，胞质中的甘氨酸合胞体持续到足月。
An histological and cytological study has been made of the development of the chorio-allantoic placenta of the albino rat. The findings contradict Duval (1891) on several important points, and partially corroborate Jenkinson (''02). The uteri described in the preceding paper (Bridgman, ''48) were studied. Additional implantation sites were fixed in Champy''s fluid to demonstrate mitochondria and Golgi bodies. Mitochondrial stains demonstrate peculiar long fibrillae in the giant cells. Mitochondria seem longer than those previously described, except in the labyrinthine syncytium, where they appear as minute granules between the fat drops along the margin of the fetal blood vessels. The Golgi material of the trophoblast had not been previously described. In giant cells and other large trophoblast cells it forms one or several basketworks around the nucleus. In the labyrinthine syncytium it consists of short rods bordering the maternal blood sinuses. The possible significance of this configuration, in conjunction with the distribution of syncytial mitochondria and fat, was discussed. The question of glycogen uptake and distribution was discussed. The most controversial observations were that the glycogen cells of the junctional zone are of fetal origin, representing original ectoplacental cells; and that there is a fetal endovascular "plasmodium" which migrates up the maternal arteries mesometrially to the junctional zone. It was also shown that the cytoplasm of the labyrinthine syncytium persists until term.
