composed of small spindle shaped cells and the acusticus root enters 
this part of the ganglion. A few very large cells, the largest in the 
whole complex, are also seen here. The ventral part of the ganglion 
still contains an area of small round nuclei of longitudinally placed 
acusticus cells. The mesial part of the ganglion is now made up 
of large cells, next in size to the very large acusticus cells. A large 
number of fibers are entering this part of the ganglion, including a 
root from the spinal Vth. tract, one from the fascieulus ecommunis

and a motor root (Fig. 4). In the cephalic part of the ganglion, 
367—363, the large cells come to oceupy the whole dorsal portion 
of the ganglion and on their mesial side appear medium sized cells, 
or in reality large cells placed lengthwise. The acustieus ganglion 
in the meantime grows smaller and disappears. Thus, besides the 
acusticus root, the fascieulus communis and general cutaneous roots 
have their ganglion cells or a part of them in this intra-capsular 
ganglion. Sections through the cephalie border of this ganglion pass 
through the neuromast roots, which are the most cephalic as well as
