MAUTHNER’S CELL 123 
Lat. Dend 
Fig. 6 From the brain of a larval Salmo clarki 32 mm. long, fixed in formol- 
Zenker and stained with toluidin blue and erythrosin. A reconstruction of 
Mauthner’s cell from a transverse series of 20 sections each 10 uw in thickness, 
magnified 250 diameters; to show the relatively small nuclues, the character of the 
Nissl substance, the great girth of the lateral and ventral dendrites (fig. 11) and 
the relations of the lateral dendrite to Deiters’ nucleus and the VIIIth nerve roots.
