point is that the cell-body stains deeply with eosin or erythrosin 
as in the case of smaller cells. The clear zones are less differ- 
entiated than those of the larger cells. The cell-bodies do not 
skrink so much as those of smaller cells and sometimes do not 
show even a slight trace of shrinkage. For a better compari- 
son we will summarize the various descriptions of the spinal 
ganglion cells which have just been given. 
I. Larger Cells. 
A. Table I, Series Aand a, Fig. 1. The cells with large, 
coarse stainable masses which lie throughout the cell-body 
without showing a regular or constant arrangement. 
B. Table I, Series A and a, Fig. 2. The cells with large, 
coarse stainable masses only at the periphery. Smaller masses 
fill up the remaining part. 
C. Table I, Series A and a, Fig. 3. The cells with large, 
coarse stainable masses which lie throughout the cell-body, 
showing a regular, concentric arrangement. 
TI. Smaller Cells. 
A. Table I, Series Band b, Fig. 4.. The cell-body of 
small size, stainable masses accumulated at the periphery of the 
cell. The cell-body stains deeply in eosin and erythrosin. After 
fixing it has a tendency to shrink markedly. 
B. Table I, Series Band b, Fig. 5. The cell-body is 
of smill size. Stiinable misses are large and distributed 
thoughout the cell-body. The cell body stains very deeply 
as in the former case. There is no regular arrangement of the 
stainable substance. After fixing it has a tendency to shrink 
markedly. 
TTI. Intermediate Cells. 
A. Series C. The cell-body small or large size. The 
stainable masses are large and coarse and are distributed 
throughout the cell-body with or without showing a concentric 
arrangement. The cell-body stains deeply as in the case of 
smaller cells. These cells have a tendency to shrink slightly. 
B. Series C. The cell-body is of small or large size. The
