nerves and arises in essentially the same manner as in embryos 

 of the turtle. 



The otic ganglion arises, in embryos of the chick, in the path of 

 a tract of sympathetic fibers which emerge from the sympathetic 

 plexus surrounding the carotid artery, primarily from cells which 

 are derived from the superior cervical and the geniculate gangha. 



The sphenopalatine ganglion arises, in embryos of the chick, 

 primarily from cells which advance peripherally from the genic- 

 ulate ganglion along the great superficial petrosal nerve, but 

 probably receives cells also which advance peripherally from the 

 Gasserian ganglion along the maxillary nerve. 



The relatively small submaxillary ganglion is genetically related 

 to the mandibular nerve. 



5. In embryos of the pig, as set forth in an earlier paper, the 

 ciliary ganglion is genetically related to the oculomotor and the 

 ophthalmic nerves The sphenopalatine ganglion arises from cells 

 which advance peripherally from the Gasserian ganglion along 

 the maxillary nerve. The otic and the submaxillary ganglia are 

 genetically related to the mandibular division of the trigeminal 

 nerve and probably receive cells from both the Gasserian ganglion 

 and the wall of the rhombencephalon.
