of an eight-month child, a ten-year child, an eighteen-year 
nullipara, and of an eighty-two-year-old multiparous woman. 
The youngest shows irregular folds with small outpocketings. 
The folds, we believe are mucosal folds such as we have found 
in our specimens. The glandular rudiments are very small in 
comparison with those of our specimen of a day old, and really 
appear in shape much more like the glands of our six-month 
fetus. The ten-year-old specimen shows small, irregular, short 
tubular outgrowths with some anastomoses and irregular folds. 
Here the type does not correspond at all to any of our specimens. 
The branchings are few and dissimilar to those found by us. 
The short slender tubular glands here also appear more like 
small outgrowths found in our six-month fetus. 
The eighteen-year-old specimen fits well into our series between 
the fourteen- and the twenty-five-year-old stages. The short 
narrow stalk and T-like divisions which we describe are not 
found, but instead a Y-like branching from a longer stalk. One 
arm of the Y has one or two Y-like subdivisions, whereas the 
other arm sends off many irregular single branches which further 
subdivide. Several branches extend for some distance toward 
the muscular coat, and one gives off a branch which returns 
one-third of the distance to the uterine lumen, then turns 
sharply and returns in its original direction. Many terminal 
branches have enlarged ends similar to those we have found. 
Anastomoses with other glands are present. 
The eighty-two-year-old specimen is a quite remarkable one. 
Many cystic tubules are found at the ends of short, narrow 
tubules. Anastomoses between these cysts by means of small 
tubules are found. The cystic enlargements are elongated oval 
structures and are found closely crowded and near the surface 
epithelium. As is well known, the mucosa is thin and the entire 
depth of the gland is only about one-third that of our adult 
specimen and even less than that of the eighteen-year-old model 
of Hedblom. 
The work of Scammon reported at the meeting of the American 
Association of Anatomists (19) shows that some interesting 
phases may have been overlooked. It is extremely important
