Fig. 333. Auditory granule layer of the Dog, with the parts, ad- 

 joining. The lettering corresponds to two specimens, from one of 

 which the part extending from / to I was taken. The commencement 

 of the arch of Corti, together with the internal hair cells, is here much 

 displaced outwards ; the granule layer has been considerably teazed 

 out. Magnified 610 diameters, a, Fasciculi of nerves represented 

 diagrammatically ; 6, foramina nervina ; c, granule cells, with pro- 

 cesses and intervening fine fibrils, which in part run to the foramina 

 for the passage of the nerves ; d, spiral band of fibres upon the inner 

 hair cells, curving, as it would appear, in part from the radial fibrils ; 

 e, heads of the internal pillars ; g, commencement of the lamina 

 reticularis ; h, hairs of the internal hair cells ; i /, capitular laminae 

 of the internal pillars ; Jc I, distinctly varicose nerve fibrils becoming 

 lost at the level of the internal hair cells.
