ganglion form short ciliary nerves. The communicating branch 

 from the ophthalmic which unites with one of these distal 

 branches sends a few fibers into the ganglion. The remaining 

 fibers run along with the distal branch to the eye and form long 

 ciliary nerves. He finds that the cells of the ganglion are uni- 

 polar and that their unbranched processes form the short ciliary

 terminate in brush-like endings about the cells in the proximal 

 three-fourths of the ganglion. The fibers from the ophthalmic 

 which enter the distal portion of the ganglion terminate about 

 the remaining cells in the distal fourth. He failed to find a sym- 

 pathetic root. Stimulation of the oculomotor nerve causes
