enlargement (Fig. 3). In general the cell group is found nearer 

 the cord. In this region, the group seems to contain a smaller 

 number of the cell-bodies than at the lower levels. 



From the above it is clear : First, that these cells are located 

 within a definite region in the dorsal root, not scattered, but form- 

 ing a group. Second, the cells are contained within well-devel- 

 oped capsules as in the case of the mature spinal ganglion cells. 

 The latter fact shows that the cells found in this group are not at 

 this time migrating, since migration could not occur after the 

 formation of the capsule. The detailed investigation of this cell- 

 group is now in progress, and the suggestion of a name for it is 

 reserved until a more complete examination has been made.
