the Temperature of the Head. 



175 



The following is a summary of the principal results ; 



1st. The whole of the 2nd tier is, in the majority of cases, of higher 

 temperature than the 1st tier, on both sides of the head ; with the 

 exception, that on both sides, the 1st district is generally of higher 

 temperature in the 1st tier than in the 2nd tier. 



2nd. The whole of the 2nd tier is. in the majority of cases, of higher 

 temperature than the 3rd tier, on both sides of the head; but this 

 majority is much less than that possessed by the 2nd tier over the 1st 

 tier. 



3rd. The whole of the third tier is, in the majority of cases, of 

 higher temperature than the 4th tier, on both sides of the head. 



4th. The whole of the 4th tier is, in the majority of cases, of higher 

 temperature than the 5th tier, on both sides of the head. 



5th. The whole of the 6th tier is, in the majority of cases, of higher 

 temperature than the 5th tier, on both sides of the head. 



The mean quantitative results are as follows : 



Left side. Might side. 



1st district, 1st tier, superior in temperature to 



1st district, 2nd tier, by 0-03 C. (0-054° F.) . . 0*04° C. (0-072° F). 

 Remainder of 2nd tier, superior to 1st tier, by 



0-155° C. (0-279° F.) 0-165° C. (0'297 c F.) 



2nd tier, superior to 3rd tier, by 0*08° C. (0-144° F.) , 0*068 n C. (0-122° F.) 

 3rd tier, superior to 4th tier, by 0*296° C. (0*532° F.) . 0-324° C. (0-583° F.) 

 4th tier, superior to 5th tier, by 0-312° C. (0'561° F) . 0-302° C. (0*543° F.) 

 6th tier, superior to 5th tier, by 0' 26° C. (0*468° F) .0*273° C. (0*491°F.) 



It will be seen from the above figures, that the difference between 

 spaces of adjoining tiers on one and the same side of the head is nearly 

 as great as the difference between symmetrically situated spaces of 

 the two sides. The order in which the tiers come, as regards their 

 temperatures, is as follows : 



2nd tier — 3rd tier — 1st tier — 4th tier — 6th tier — 5th tier ; this order 

 holding good for both sides of the head. 



(&.) Comparison of spaces situated in two adjoining districts of the 

 same tier, 50 observations on each pair of spaces. 



The following is a summary of the principal results : — 



1st. The 1st district is of higher temperature than the 2nd district, 

 in the majority of cases, in the 1st and 5th tiers, on both sides of the 

 head. 



2nd. The 2nd district is of higher temperature than the 1st, in the 

 majority of cases, in the 2nd, 3rd, 4th, and 6th tiers, on both sides of 

 the head. 



3rd. The 3rd district is of higher temperature than the 2nd district, 

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