large lumina. In adults the glands forked near their ends- 
Nagel (’91) found that the glands of the corpus developed much 
later than those of the cervix, although he figured glands in the 
corpus of a 17-cm. fetus. Wyder appears to have been about 
the only one who did not find glands in the corpus at birth and 
is the only one who has stated that the development of the glands. 
is entirely independent of age. 
The peculiarly shaped lumen of the uterus of the fetuses and 
young adults has been noted by other investigators and is 
apparently constantly present. No explanation of this peculi- 
arity has been offered. The theory that it may be due to the 
union of the early Miillerian ducts is worthy of consideration. 
In all of the specimens upon which this study is based, glands 
or rudiments of glands are found, from the six-month fetus 
onward. In the six-month fetus they are present as small 
outpouchings from the folds of epithelium. Contrary to the 
findings of Moricke, our specimen of new-born shows glands, 
often closely crowded, without branches and not as yet tubular, 
but rather having the appearance of simple outgrowths with 
enlarged flattened end pieces and slightly constricted stalks. 
This shape is typical of early stages of uterine glands as well as 
of the early stages in the development of many other glands. 
The tubular shape and T-shaped branches appear in the first 
year, however. 
The glands increase in length and in number of branches 
during the early years of life, although the growth is not extreme, 
and the stages from one to seven years show no marked differ- 
entiation. The T-shaped branches and the growth from the 
ends of the folds of the mucosa are constant characteristics. 
Just before puberty, glandular growth seems markedly 
hastened, although the mucosa may not be much thicker. Of 
the glands modeled many have T-shaped branchings. Further 
branchings and subdivisions, beyond the T-shape, are first 
observed at this time. Some of the glands are closely crowded 
as in younger stages. The tubular shape is constant, although 
enlarged ends and irregular enlargements of the stalk are found. 
The short, constricted necks are here present.
