DEVELOPMENT OF UTERINE GLANDS 211 
and would be valuable to have models of the various stages 
from birth to three months of age, instead of only at birth. 
Then, corresponding to the periods of growth, as indicated by 
lengths of the uterus, models of the sixth year and again about 
the eleventh would be desirable. The models of seven months 
and of four years as indicated are quite similar. A specimen 
from a seven-year-old child shows rather poorly developed 
glands—certainly not much beyond the four-year stage—while 
a model of a twenty-one-month child is very similar to the one 
of seven months. 
It cannot be denied, therefore, that it would be interesting to 
reconstruct more of the stages of the glands between four and 
fourteen years as well as during the menstrual period, the meno- 
pause, and of a parous woman, and that these stages should be 
included in this paper. Unfortunately, we have not found the 
material available. 
CONCLUSIONS 
1. Glands are found in the corpus of the uterus in a six- to 
seven-month fetus and in all material studied beyond this age. 
2. The earliest glands are small irregular outpouchings from 
semilunar mucosal folds, later developing constricted necks and 
enlarged end pieces similar to many other gland rudiments. 
3. The necks persist even to the adult stage, the enlarged 
ends becoming tubular and dividing T-like with sometimes a 
second longitudinal division of the end branches. 
4. The stalks follow an oblique course in the adult, sometimes 
almost a spiral one. 
5. Near the muscle layer the branches run parallel to the 
surface and all in one direction, sometimes forming a network by 
anastomoses of different branches. 
6. The greater part of the glandular tissue lies in the lower one- 
third or fourth of the endometrium. 
7. Adult uterine glands are compound, anastomosing, tubular 
glands,
