42 ROBERT OGDEN AND SHEPHERD IVORY FRANZ 



corresponding segments were dragged over. The animal returned to its 

 food about a half minute after it had successfully negotiated the par- 

 tition. For about four or five minutes subsequently the right side 

 could be used only with great awkwardness, but at the end of that 

 time there was an apparent return to its former ability. There was 

 a facial cyanosis for fully half an hour subsequent to the convulsion. 

 Another similar convulsion occurred the same evening, about 8 hours 

 after the first one. Others have been noted repeatedly both by one of 

 us and by an assistant, and they have appeared to be of the same char- 

 acter as that described. The monkey has not been able to use the right 

 hand as well as he did previous to the occurrence of the convulsions, 

 and some of the apparent deterioration in the proper use -of that hand 

 may reasonably be ascribed to the unknown convulsive-producing 

 condition. 4 



Summary. In this experiment although general massage was given 

 to the paralyzed segments there was less recovery than in those cases 

 in which special attention was paid to the individual muscles and 

 nerves. The recovery has been sufficient to enable the animal to feed 

 himself, and to perform other necessary acts, but not sufficient to 

 make the finer kinds of movements; the muscles remain weak. This 

 case is complicated with a unilateral epileptiform condition, which 

 may have been the reason for a slight deterioration in the use of the 

 right hand. 



4 Since the above was written another convulsion has occurred in the presence 

 of one of us, and its characters have been noted. The monkey had been eating 

 a piece of carrot for about three minutes, when the food which he had been hold- 

 ing was dropped to the floor, the right hand was clenched to make a fist, then 

 there was a tonic flexion of the forearm on the arm, and this was followed by a 

 slow tonic abduction of the arm to about 75 degrees from the normal position. 

 A sudden relaxation then occurred, followed by a series of clonic movements in 

 the whole of the arm area, and at this time the monkey cried several times. 

 From this time the convulsion was purely clonic, the right leg following the 

 arm, and in a few seconds the left side followed the right in a series of severe 

 and extensive movements. The convulsion ended in 27 or 28 seconds, with a 

 gradual lessening of the rate and of the extension of the movements, and as 

 soon as the clonic movements had stopped the animal took up the piece of car- 

 rot which it had been eating previous to the attack. The convulsions have 

 been coming at longer intervals, and they have been observed chiefly after the 

 animal begins his morning meal.
