Mr. Shaw on the Facial Nerves. 131 



sibility in the inside of the nostril, so that we are unable to 

 say whether the branches of the 5th, which pass to the inside 

 of the nose, were paralyzed. 



The state of the right eye-lids and eye-brow corresponded 

 with those of patients who have paralysis of the portio dura, for 

 both the orbicularis oculi and corrugator supercilii were so 

 completely paralytic, that he could neither close his eye, nor 

 knit his brow on the right side. 



On examining how far the branch of the 5th, which passes 

 to the eye and eye-lids, was affected, we found that the symptoms 

 did not exactly correspond with those observed in tlie parts regu- 

 lated by the otiier divisions of the 5th pair, and particularly in 

 the degree of sensibility ; for when a hair was pulled from each 

 temple, or from the eye-brows, the pain felt in tlie two sides 

 was nearly the same. This and the state of the levator pal- 

 pebree led us to suspect that the first division of the 5th was 

 not so much affected as the 2d and 3d divisions of the same 

 nerve. I may farther observe, that neither the temporalis, nor 

 masseter muscles of this side were paralyzed. The reason of 

 this will perhaps be ascertained, by a more minute dissec- 

 tion of the 5th than we have as yet made. The motions of the 

 eye-ball were so far perfect, that he could follow the pencil when 

 it was carried before him, but he could not direct both eyes 

 truly, he saw double. The contraction and dilatation of the 

 pupil of the right eye were much the same as in the other eye. 



All traces of the injury behind the ear have disappeared ; he 

 was, for some time after the accident, very deaf, but he is 

 quickly recovering from his deafness. This latter part I have co- 

 pied from my notes made on the 17th of October ; but on the 

 16th of November he was still very deaf on this side. He could 

 not hear the ticking of a watch when it was held close to his ear. 



State of his Tongiie. — He can put it out and move it in every 

 direction, with the greatest ease: the motions are all ap- 

 parently correct and natural ; he can throw a morsel from one 

 side of the mouth to the other, and towards the throat, and he 

 can pick it out from between his cheek and teeth. 



These observations led us to conclude, that not only the 

 motor lingugc, or 9th nerve, but also the glosso pharynggeal were
