RELATIONS OF AUDITORY NERVE TO ORGAN OF CORTI. 179 



(d) ; the spiral fibrous layer (c) ; the processes of the internal 

 hair cells (b), which lie between the fibres of this layer as in a 

 network of threads; and lastly, the hair-bearing cuticle (a). 

 The nerve fibres are seen entering the granule layer in the 

 form of larger (g) and smaller (/) fasciculi of axis fibrils. I 

 have also, as at g, seen some of the stronger fasciculi of fibrils 

 undergo division. Some of the slender nerve fibrils run upwards 

 between the hair cells, and these, after what has been already 

 stated in page 173 et seq., must be regarded as external radial

fibres, which are only passing through between the internal hair 

 cells and the pillars. Whether there are yet other nerve fibrils 

 continuous with the processes of the granule cells, which either 

 indirectly through these, or directly, as Max Schultze (50) and 

 Deiters (13) admit, are continuous with spiral fibres, or curve 

 round into the latter, so that these last must be regarded as
