Explanation of Plates. 
Figures 3 to 44 are drawings of cells and nerve terminations in the ciliary 
ganglion of the hen as seen under a 2—mm. oil immersion objective. As far as practi- 
cable the illustrations have been made with the aid of a camera lucida, Figures 3 to 
9 show endings of oculomotor fibers; Figures 11 to 13, endings of trigeminal fibers.

Plate 4. 
Calyx endings. Methylene blue. 
Calyx ending. Cajal silver method. 
Calyx ending. Methylene blue and alum carmine. The cell-body and 
cell capsule with amphicyte nuclei are stained red. 
Brush ending. Methylene blue. 
Brush ending. Cajal silver method. 
Arborescent ending, Cajal silver method. 
Ganglion cell from trigeminal region. Methylene blue, 
Plate 2. 
End net. Methylene blue. Certain of the circular or oval granular 
bodies appear to be amphicyte nuclei which have taken the blue 
stain. Others are plainly expansions of the nerve fibrils. 
End nets. Methylene blue and alum carmine. The cell bodies and 
amphicyte nuclei are stained red. 
Isolated cell from a macerated and teased preparation of the ciliary 
ganglion. Acid fuchsin. The coarse medullated fiber is an oculomotor 
neurite, ending probably in a calyx; the finer medullated fiber is a 
ciliary neurite arising from the cell-body. 
Diagram of the ciliary ganglion and its connections in the hen, 
showing the relations of the oculomotor and trigeminal fibers to the 
ciliary neurones. N. cil. brev., short ciliary nerves; n. cil. long., 
long ciliary nerves; n. oc’mot., oculomotor nerve: neur. cil.', 
short ciliary neurone (pupil-dilator?); neur. cil.!', short ciliary 
neurone (pupil-constrictor); neur oc’mot., oculomotor neurone 
(pupil-constrictor); neur. trig.', trigiminal neurone (pupil-dilator ?) ; 
neur, trig.!', trigeminal neurone (sensory ?); rad. long., long root: 
reg. oc’ mot., oculomotor region of ganglion; reg. trig., trigeminal 
region of ganglion; rm. comn., ramus communicans; rm, ophth, 
trig., ophthalmic division of trigeminal nerve.
