DESCRIPTION OF PLATES. 
The auditory epithelium is colored yellow. The nerve fibers are violet, and the 
medullary sheath neutral tint. The capillaries are violet of different tints, due to 
the variously stained blood corpuscles which fill them. 
Lettering used uniformly throughout the figures. 
m. == medullary sheath. c. = capillaries. 
n.f. = nerve fibers. n. = nuclei. 
t.é. == terminal enlargement. A. = terminal hairs. 
h.c. = hair cells. 
All drawings were made with Abbé camera lucida on Bernhard’s drawing 
table, to avoid distortion.
