as regards the position of knee and elbow her perception is likewise 

 inaccurate but to a less degree. The position of the upper-arm and 

 leg is ascertained with tolerable accuracy. There is complete astereoq- 

 nosis of the right hand. Not a single object pul into this hand is 

 recognized. The patient does not know whether she has got something 

 in this hand or not. Oftenest she drops it. 



All these disturbances of sensibility to the right remained stationary 

 during the three months the woman was under observation. 



(hi the contrary the motility of the right limbs had suffered only 

 slightly. In the week after the lesion she complained of a certain 

 feebleness of the right extremities. 



A paralysis however has never been observed. The complaint was 

 a passing one, and the only fact ascertained was that the right 

 shoulder hung somewhat lower than the left one. Rapid as well as 

 subile movements could be performed with the right extremities, e. g. 

 to count money, or to bring the linger to the top of the nose, were 

 done nearly as well by the right hand as by the left. Here is "///>/ 

 a slight right-sided cerebral ataxy, and there, docs not exist any vestige 

 of athetosis; or choreic or other involuntary movements. The dynamo- 

 meter in the hand reached 50 ii;'. on both sides. 



The skin reilex-actions, as the abdominal, cremaster- and plantar- 

 reflex-actions, are normal and on both sides equal. The deep reflex-actions, 

 those of the tendo Achillis and of the knee are not increased, there 

 is no clonus of foot or knee. Neither is there a distinct difference 

 of tonus, nor any atrophy in the muscles of the two halves of the bod v. 

 There have been no disturbances of speech or articulation. As the 

 patient had never learned reading or writing, possible disturbances 

 in reading or writing were not to be stated. Her condition remained 

 unaltered until her death on the 24 th . of March 1908. 



The brains, which were kindly put at our disposition from the 

 laboratory of Prof. Kuhn, were indurated in formaline for a few 

 days. Thereupon frontal sections of 1 cm. were made through both 

 hemispheres. The only degeneration that may be observed macros- 

 copically is a focal destruction in the medial and caudal portions of 

 the left thalamus opticus. 



Consequently for the purpose of microscopical examination there 

 was made a series of frontal sections through the left hemisphere, the 

 most proximal sections of these passing through the caudal ends of 

 the frontal convolutions, the temporal pole and the commissura 

 anterior, whilst the most caudal section passes behind the caudal end 

 of the fissura Sylvii, through the caudal border of the gyrus supra- 

 marginalis, the praecuneus and the splenium corporis callosi.
