Partial anaesthesia of the thermal end-organs noticed in first two 

 subjects, due to their having had their hands in the hot water of the 

 wash-tub a large part of the time. The results of other experiments, 

 which are not given here, in no way conflict with the results given 

 above, but are withheld for the reason that they would add nothing 

 to what has already been stated. 



It will be seen, if we are warranted in generalizing from the above 

 results, that the maximum number of cold-spots is to be found in the 

 Ethiopian race, and the minimum number in the American, while the 

 heat-spots reach the maximum number in the American race, and 

 the minimum number in the Mongolian race. If the number of tem- 

 perature end-organs is in any way effected by climatic conditions, 

 we would expect to find the races standing in the following order, 

 with regard to the maximum number of cold-spots and the minimum 

 number of heat-spots: Ethiopian, Malay, Mongolian, Caucasian 

 and American. The last two, however, might be reversed.
