This bundle after emerging lay free on the surface of the arach- 

 noid. The appearance of the free end indicated that it had been 

 stretched and broken in removing the brain from the cranial 

 cavity. 



Several ganglionic swellings are visible, the largest one in the 

 brain from which the figure was drawn, at the point (fig. 32, 

 gn.) where the nerve crosses the artery. Just caudad to this 

 ganglion, as more clearly shown in figure 33, the bundle divides 

 into two strands. A short distance rostral to this ganglionic

mass, a similar strand is given off from the main trunk. These 

 strands follow the branches of the anterior cerebral artery, as in- 

 dicated in figures 32 and 33, ramifying to the secondary branches 

 of these vessels, and at intervals they give off fine twigs which 

 penetrate into the muscular walls of the arteries. 



Several of the strands were traced continuously to the points 

 marked x in figure 32, where the respective arteries dipped into 

 the fissures. On the same brain, and on others, similar strands 

 were found on all of the arteries examined in this region of the
