almost restored ; but there is still sensible hypersesthesia in it, as 

 well as on the inner side of the palm of the hand. There is also 

 some stiffness in that finger, and a complete inability, when the fin- 

 gers are extended, to bring them into opposition with one another. 



The spot on the upper arm to which cold was applied is now quite 

 healed, and all swelling has subsided ; but the ulnar nerve is still 

 very sensitive on being touched. 



The weakness of the left hand in grasping objects, as in using a 

 fork at dinner, &c., even ten days after the experiment, was most 

 perceptible.

There was still considerable numbness in the little finger and on 

 the inner side of the palm of the hand. The fingers could now be 

 extended almost as completely as those of the right hand, but they 

 could not be easily expanded, or brought into opposition with one 

 another. At times the nerve was very painful along its whole course, 

 from the elbow downwards. This is mostly the case after the arm 

 has been used a little. Pain at these times, even if not actually pre- 

 sent, was easily induced by placing the arm in a dependent position 

 so as to cause congestion of its vessels, and it was immediately re- 

 lieved by elevating the limb above the head so as to deplete the ves- 

 sels. The nerve was very sensitive to pressure all along its course, 

 from the elbow downwards, although all painfulness arising from the 

 inflammation produced in the cutaneous tissue by the cold had dis- 

 appeared for some days. 



On both hands being held for some minutes in a stream of running 

 water at a temperature of 14'4 Cent., considerable pain was expe- 

 rienced in the little finger and inner side of the left hand ; and on 

 withdrawing both hands their temperature was 



Right little finger. Left little finger.
