lingual branch of the fifth. They pass thence through the sub- 

 raaxillary ganglion to the glands. 



The cerebro-spinal parotid branches pass through the lesser 

 superficial petrosal nerve from the tympanic plexus to the otic 

 ganglion, and thence to the auriculo-temporal nerve which sends 

 twigs to the gland. (Fig. 65.)

I. The effects of experimental stimulation of the cerebro-spinal 

 glandular branches, so far as we know, are alike for all the glands. 

 But owing to the greater facility with which the sub-maxillary 

 gland can be reached and its nerve isolated, research has been 

 chiefly devoted to it, by operating on the chorda tympani and 

 the other nerves supplying the gland.
