enumerate them ; but it is necessary, in this inquiry, that we 

 may compare them, with the phenomena observable in cases 

 of partial paralysis. 



In the following case, (which nearly corresponds with several 

 others I have examined,) the symptoms will be described in the 

 order that has been followed in the last. 



J. Cooper. — This man's general appearance is completely 

 that of an old paralytic, but the distortion of his face is more 

 remarkable than usual, in consequence of the right or para- 

 lyzed side being marked with a red blotch. 



The arm and leg of the same side are nearly powerless, his 

 intellects are much impaired, and his memory gone. The history 

 of his case was given very clearly by his wife ; according to 

 her account, her husband was, for the first time, attacked with 

 apoplexy about seven years ago ; from this attack he gradually 

 recovered, but at the end of twelve months he was a second 

 time seized, and, since that period, he has had two distinct 

 attacks every year ; for the last two or three years, he has been 

 nearly in the same condition as at present. 



State of the cheeks and mouth. — When he is made to laugh, 

 the right cheek rises in the same degree with the left ; when he 

 blows, (he always burst into a laugh when asked to whistle,) 

 the buccinator of the right cheek is in as much action as on 

 the other side. When his nose is irritated by the inhalation 

 of ammonia, the actions of the muscles, preparatory to sneezing, 

 are equal on both sides of the face. These phenomena prove 

 that the muscles of both cheeks are perfect in their actions 

 as far as they are regulated by the respiratory nerve ; they may 

 be compared with the state of the same muscles in the case 

 last related, when the act of sneezing was excited. 



The next inquiry was, how far those actions were entire, which 

 are dependant on the branches of the 5th pair. 



The right cheek, and the same side of the mouth, fall lower 

 than the left. When a piece of bread was put between the teeth 

 and right cheek, the patient could not push it from its place 

 with the buccinator muscle, but was obliged to pick it out with
