On the Temperature of the Head. 



[Mar. 7,' 



4th. The 4th district is of higher temperature than the 3rd district, 

 in the majority of cases, in every tier, on both sides of the head. 



. 5th. The 4th district is of higher temperature than the 5th district, 

 in the majority of cases, in the 1st tier, left side ; in the 2nd and 3rd 

 tiers, right side ; and in the 4th tier, on both sides of the head. 



6th. The 5th district is of higher temperature than the 4th district, ' 

 in the majority of cases, in the 1st tier, right side ; and in the 2nd and 

 3rd tiers, left side. 



The mean quantitative results are as follows : — 



Left side. Bight side. 



0-037° C. (0-066° F.) 

 0-043° C. (0-077° F.) 

 0-032° C. (0-057° F.) 

 0-012° C. (0-021° F.) 



From the above it can be seen that the mean difference between 

 districts is much less than that existing between tiers. The order in 

 which the districts come, as regards their temperatures, is as follows : — 



4th district, 5th district, 3rd district, 1st district, 2nd district ; this 

 order holding good for both sides of the head. 



Lastly, if we take the three groups of examinations, namely, those 

 on the comparative temperature of the two sides of the head : those on 

 the comparative temperature of adjoining tiers on one and the same 

 side ; and those on the comparative temperature of adjoining districts 

 on one and the same side, we have the following values : — 



Comparison of the two sides of the Head.

the head over the other 61*074 - 0-247° C. (0'444° F.)
