BILATERAL ATHETOSIS. 131 



of the right upper extremity especially attracted 

 attention. The following description is compiled 

 from notes taken on various occasions : 



The limb was useless for any purposive move- 

 ments; there was no voluntary power over the 

 hand, and but little over the shoulder and elbow. 

 When a flower was held up to the child, he looked 

 at it and made a noise, evidently indicating his 

 pleasure, then moved his left hand to the flower, 

 took hold of it, and tried to put it to his mouth. 

 He could not take the flower with his right hand. 



The wrist was frequently kept half flexed, while 

 the fingers were extended and flexed generally 

 altogether, in a slow and rhythmical manner. Pro- 

 nation and supination were not common ; the move- 

 ments of the wrist were usually confined to flexion 

 and extension of the fingers as described. 



The hand was moved when pricked. There was 

 no difference between the similar measurements in 

 the two arms, but there was some rigidity of the 

 right arm. The right leg was weak, but presented 

 no athetosis. 



Here the condition of the limb was associated 

 with brain disease and convulsions. The move- 

 ments occurred in a paralyzed arm, and were more 

 limited in extent than in Case I. 



CASE III. Double Atketotis not associated with 

 Epilepsy.

 a playful, intelligent, pleasing little girl, goad and 

 well-behaved, and soon became a general favourite.
