show some very interesting results, and the plan was to incor- 
porate these results in this paper. However, lack of material 
prevented this at this time. 
There is an even greater lack of description of the characteristics 
of the glands during development. Lewis states that the glands 
develop at the bases of folds. In Keibel and Mall’s Embryology 
(12) very little attention is given to their development and only 
one investigator (Wyder, ’78) is quoted. This investigator 
states that the glands develop independently of the age of the 
individual. 
It seems, therefore, from this brief review of the literature 
that very little is known of the development of the uterine 
glands or of their ultimate form. For that reason, the senior 
author suggested that this problemshould yield results worthy of 
publication. The models were all constructed by the junior 
investigators. 
DEVELOPMENT OF THE GLANDS 
The material upon which this study is based consists of serial 
sections of portions of the corpora of uteri of fetuses and of 
adults. The youngest uterus studied was of a six- to seven- 
month fetus, the oldest a uterus of a twenty-five-year-old virgin. 
The entire fundus of the six- to seven-month fetus was sectioned 
and a model made of the lumen of the organ, including the 
epithelial lining and any outpouchings or glands. This model is 
shown in figure 1. An interesting particular of this stage is 
the peculiar S-shaped lumen with irregular sides. There are 
folds of the uterine mucosa from which small outpouchings 
protrude. 
The irregular folds of the epithelium on the sides of the lumen 
give the effect of a scalloped edge. Rudiments of glands are 
present. ‘The most prominent epithelial folds are found on the 
anterior and posterior surfaces and are directed toward the ~ 
cervix. Only two are shown in the model. These two run 
almost transversely across the surface of the lumen and have 
the appearance of crescent-shaped, hood-like evaginations
