herent to the side of the head. Sections of the cord show 
that it is fibrous and infiltrated with round cells along the 
course of the blood-vessels. 
The skin is thickened and much of the epidermis has fallen 
off. At points the epithelial cells form mounds without any 
horny changes in them. The muscles, blood-vessels and 
nerves of the extremities are converted into one fibrous mass 
composed of spindle-shaped cells, giving much the appearance 
of myomatous tissue, infiltrated at points with round cells. 
The cartilages are still hyaline, richer, however, in cells 
than is normal. The bone formation is very extensive, which 
at the border line between it and the cartilage shows peculiar 
changes in the latter. There is a mass of this changed car- 
tilage in the os calcis without any surrounding bone forma- 
tion. In general the cartilages are deformed, due no doubt 
in part to the distorted joints. Where the hand is adherent 
to the side of the head the epidermis of the two is continuous 
and blended. The skin and subcutaneous tissue are thick- 
ened, being composed of one mass of round cells. 
The form of the brain and its structure are pretty well pre- 
served, while the tissues of the liver and intestine are necrotic 
and macerated. It appears as if the growth of the embryo 
had been retarded with a continued growth and change in 
the connective tissues. Then, after its death, the embryo was 
retained in the uterus for some time. At points all over 
the body there are thickened spots in the skin which are 
epithelial in nature, but they are located below the epidermis.
