120 A STUDY OF SOME 



ing. The legs " seemed to get stiff and to tremble." Afterwards 

 jerking of the hands, arms, shoulders, and head commenced. 

 This jerking, or chorea, is still present, though less marked than 

 before. She has, however, a choreic or spasmodic affection of the 

 muscles of respiration and phouation, as her breathing and her 

 speech are very irregular. Her speech is not infrequently in- 

 terrupted by a sudden gush of inspiration, which produces an 

 ascending note. She has no chorea of the legs, but her gait is 

 markedly spastic, and she walks with great difBculty. Her 

 face, too, is somewhat choreic, and her tongue deviates slightly to 

 the left. 



The case was doubtless one of disseminated sclerosis in which 

 the lateral columns were markedly affected. 



An examination of the plate shows that she barely, if at all, 

 raises the feet from the ground. The amount of lateral sway, too, 

 is small, and her steps are exceedingly short. 



In Plate 541 is seen the walk of an extremely choreic girl, — a 

 chorea which had lasted from early infancy and appeared to be of 

 organic origin, probably a disseminated sclerosis. It is therefore 

 allied somewhat to the preceding case. At first the gait appears 

 spastic. However, the leg which is at one instant rigid and ex- 

 tended is at the next instant flexed. It is interesting to note the 

 spastic condition of the right arm, which, during the step, is rigidly 

 extended along the side of the body. The head and neck and 

 even the toes are violently contorted. Of course in such a case 

 no two steps could be alike, and the gait could only be termed 

 irregular. 



Other Abnormal Gaits. 



In Plate 551 is represented an epileptic suffering from a 

 spastic hemiplegia which is more pronounced in the arm than in 

 the leg, and which dates from early childhood. The gait is in 

 some respects a spastic gait. 



Somewhat similar to it is the gait, seen in Plate 561, of a 

 rachitic and hydrocephalic subject. Here both legs are decidedly 

 spastic. 



In Plate 559 we have an instance of partial paraplegia. The 

 subject was a druggist in a country town, who had, several years 

 before, been thrown from a horse and had received a severe con- 

 tusion of the back. He gradually lost power in his legs until
