bath containing water at the same temperature as that in the 
calorimeter in order that V might approximate to the temperature 
of the calorimeter. All thermometers used were, of course, com- 
pared with a standard thermometer. In the cases observed, the 
two hands were simultaneously immersed in two precisely similar 
calorimeters. The volume of the hand enclosed in the calorimeter 
was determined by afterwards immersing the hand up to the proper 
level in a lipped beaker previously filled with water and measuring 
the overflow, or by immersing it in a vessel provided with a gauge. 
Case 1. — Man set. 46, weight 160 lbs., height 5 ft. 10 in. Marked contracture of 
the flexors of left wrist, with spastic paralysis of hand and fingers; also some deformity 
of left foot. A history was obtained indicating gradual onset of the contractures. 
At the age of two deformity was noted in the left hand and slight deformity in the 
left foot. The condition gradually got worse. The general health is good and the 
man is able to work as a telegraphist. There is some control of the movements of 
the left hand. He can extend the fingers and flex them but not normally. He uses 
the hand to a certain extent in his occupation. It is markedly smaller than the 
right. The pulse at the wrist is quite distinct. The hand feels as warm as the right 
one. The case was diagnosed as birth palsy by Dr. Henry O. Feiss, to whom I am 
indebted for the opportunity of studying it and the other case.

At 4.01 the hands were rapidly withdrawn and the fina 1 reading taken after vigorous 
stirring. Variations in the previous readings due to inadequate stirring or accidental 
contact of the fingers with the thermometer are thus controlled.
