numbered from 1 to 7 from below upwards. There are 5 districts in 

 each lateral half, formed by 4 equidistant lines drawn parallel to the 

 anterior and posterior boundaries.* The districts are numbered from 

 1 to 5 from the anterior boundary backward. Each tier measures 

 vertically on the anterior boundary line 22' 78 mm. (0*89 inch), and 

 each district measures horizontally on the median line 16'6 mm. (0'65 

 inch). The ear cuts off the greater portion of the 3rd district, the 

 whole of the 4th district, and a little of the 5th district — all in the 1st 

 tier. The following are the principal results of the examination of 

 the middle region : — 



1st. Comparison of symmetrically situated spaces of the two sides 

 of the head, 100 observations on each pair of spaces. 



As in the case of the anterior region, every space may be higher in 

 temperature on the right side or on the left side in turn. The follow- 

 ing is the distribution of temperature in the majority of cases ; — 



In favour of 



Left side. Bight side.

Thus in 34 spaces a side compared, the temperature is higher on 

 each side in 17 spaces. Taking the total number of observations, 

 3,400, and deducting 107 cases of equality of temperature, the follow- 

 ing are the percentages of times of occurrence of relative superiority 

 of temperature for the right and left sides respectively : — 



Eight side,— 49711. left side ,— 50'289. 



The following are the spaces in which equality of temperature is 

 most generally found : — - 



1st Tier. 4th Tier. 5th Tier. 



Districts— 1st, 2nd, 3rd. 2nd, 3rd, 4th, 5th. 2nd, 3rd, 4th, 5th. 



6th Tier. 7th Tier. 



Districts— 2nd, 4th. 1st, 2nd. 



The following are the percentages of superiority of temperature on 

 the right side, on the left side, and of equality of temperature, — in the 

 total number of observations : — 



Eight side — 48'147 per cent. Left side — 48' 706 per cent. 

 Equality — 3*147 per cent.
