MULLENIX.— Eighth Cranial Nerve. 
PLATE 6. 
Magnification, 810 diameters. 
Fias. 41-43. Nerve terminations in macula acustica neglecta. Sections 
parallel to the principal axis of the sense cells. 
Fias. 44-53. Sections from macula acustica sacculi, in planes nearly parallel 
to the surface of the epithelium. Sense cells shown in cross section. 
Fig. 45. Cytoplasm of sense cells shrunken away from cell walls. Space 
between sense cells largely occupied by intercellular substance. 
Fias. 44 and 46-53. Extracellular axis cylinders. 
Fig. 44. Cut ends of axis cylinders, between sense cells. 
Fias. 46, 47, 50, 51. Small axis cylinders in close proximity to surface of 
sense cells. 
Figs. 48, 50,51. Axis cylinders bifurcating at surface of sense cell and sending 
a branch to either side of it. 
Fig. 52. Tangled intercellular axis cylinders, which presented, when examined 
with low power dry lens, the appearance of being anastomosed to 
form a closed network; but when studied under high-power oil- 
immersion lens were found to be distinct. 
Fig. 53. Two of the sense cells contain filaments which present the appear- 
ance of nervous matter.
