 no end organs were ever seen at these points. 



The network which I have designated as subepithelial is

 consists of a rather fine-meshed plexus of cells and non-medul-

 the palate of the frog; the network is continuous with a medullated fiber. X 380. 



The fibers seem to radiate from beneath the sensory organs, 

 and at these points from 3 to 6 cells are usually found grouped 

 together (Fig. i\, a, a'). Into the sensory organs fibers pass 

 from the network, while others are given off at points between
