nerve. Gen. G., a cell of the geniculate ganglion. Ch. L. T., 

 the chorda-lingual triangle (Langley), formed by the chorda 

 tympani, the lingual nerve and the sub-maxillary duct. This 

 triangle contains the sub-lingual ganglion [Sub. I. G). Sitb. 

 m. G., the sub-maxillary ganglion in the hilum of the sub- 

 maxillary gland. S2tp. c. G. , superior cervical ganglion ; Ccrv. 

 S., cervical sympathetic; Inf. c. G., inferior cervical ganglion; 

 A)i. V,, Annulus of Vieussens ; 5/. G., the stellate ganglion; 

 Syiiip. c, a portion of the sympathetic chain, sp. c, a portion 

 of the dorsal spinal cord with II, III, IV ; Dr. n., the second, 

 third and fourth spinal nerves; W. R., the white rami coming 

 from these spinal nerves. 



The nerve fibers of the lingual nerve [ling.) are diagramed 

 in black. The figures show its neurons to be sensory. The 

 cells of the geniculate ganglion are also sensory (Lenhossek). 

 The nerve fibers coming from these cells join the chorda {ch. T. ) 

 and terminate in a free ejiding on the ducts of the sub-maxillary 

 gland (probably also in the sub-lingual gland). 



The fibers in the chorda tympani {cJi. T.) colored blue in 

 the figure, are comparable to the fibers of the white rami. 

 Some end in peri-cellular baskets in the sublingual ganglion 

 {sub. I. G.), others accompany the sub-maxillary duct to the 

 hilum of the gland, where they end in peri-cellular baskets. 



The sympathetic neurons of the sub-lingual ganglion {sub. 

 I. G.) and of the sub- maxillary ganglion {s2ib. ni. G.) are col- 

 ored red. The neuraxes of the sympathetic neurons of the 

 sub-lingual ganglion accompany the ducts of the gland and end 

 on the secreting cells. The neuraxes of the sympathetic cells 

 of the sub-maxillary ganglion {sub. in. G.) accompany the sub- 

 maxillary gland ducts and end on its secreting cells. 



The secretory fibers from the spinal cord leave the cord 

 through the anterior roots of the II, III, IV dorsal nerves ; 

 through their white rami {W. R.) they reach the stellate gang- 

 lion, {St. G.). They pass through this ganglion, through the 

 annulus {An. V.), through the inferior cervical ganglion {fnf. c. 

 G.), and by way of the cervical sympathetic they reach the su- 

 perior cervical ganglion, {S7ip. c. G.), and end in peri-cellular
