perfect. We next examined the state of these parts of the 

 tongue, which we suppose arc supplied by the third division of 

 the 5lh nerve. After closing his eyes, we put a little sugar on 

 each side; we asked him to put his finger to the part of the 

 tongue upon which the sugar was ; he put it up to the left side ; 

 he was not conscious that there was any on the right. While 

 the eyes were closed, we pricked each side of the tongue 

 with a needle, his expression with regard to the difference of 

 feeling, was the same as that used in describing the state of his 

 cheek. 



There does not appear to be any paralysis of the parts 

 about the_fauces, since he swallows easily; the state of his larynx 

 is also good, as there is no difficulty in speaking, or any impe- 

 diment to utterance, farther than what may be explained by the 

 paralysis of one side of his mouth. 



Neck and Shoulders. — There are no symptoms of paralysis in 

 any of the muscles of his neck or shoulders ; but the observations 

 on the actions of the muscles of the shoulder were at this time 

 imperfect, as his broken clavicle was not yet united ; however^ 

 on the 1 6th of November I found the arm so well, that there 

 was no difficulty in making the experiment; and then, although 

 the face was as much paralyzed as ever, I was satisfied that 

 there was not the shghtest symptom of palsy, in the actions of 

 the muscles of the shoulder, or of the leg. 



This case differs from the common examples of partial pa- 

 ralysis of the face, and also from those of hemiplegia. From the 

 first, not only in there being evident marks of paralysis while 

 the muscles of the face are at rest ; but in the power of the 

 muscles being lost during the action of eating, and also in the 

 sensibility of the skin of the same side, being in a great measure 

 destroyed. 



The first difference which we observe in it, from one of 

 common hemiplegia, is that the paralysis is confined to the 

 face. Secondly, that the paralysis is on the same side with 

 that on which the head is injured. Thirdly, that the palsy is 

 more evident, when the patient is made to sneeze or laugh. 

 Shewing that in this instance the muscles are deficient, not only 

 in the powers which they receive from the 5th, but also in the
