this point definitely but there are other fibrils which end in the 

 epithelium between the sensory spots. From this it is evident 

 that a part at least of the fibrillae of this network are sensory in 

 function. And it is not clear to me why the cells should be 

 grouped together beneath the sensory organs unless they have 

 some connection with them.

 aration (period of degeneration five weeks); the cells and fibers apparently show 

 normal structure, and were normally stained, a, a\ groups of cells beneath 

 Sensory organs; d, b\ degenerated medullated fibers of which b is connected 

 with the network; c, 3. medullated fiber continuous with the network and show- 

 ing normal structure for a short distance at its distal end. X 225.
