syphilised population had if anytliing a rather subnormal temperature ; but the 
removal of these 18 temperatures gave for the weak-minded population a mean- 
temperature of 98-533 ± -021, which although slightly reduced is still significantly 
greater than that of the normal criminal population. I think we must conclude 
that none of the observed pathological states is the source of the higher temperature 
of the weak-minded, but whatever that source is, it is intensified in the presence 
of either epilepsy or syphilis*. 
In the paper by Williams, Bell and Pearson, already cited, it is shown that 
body temperature falls with age up to the adult stage. From the present data 
we see that from age 22-5 to age 85-5 the fall is continued. Table XXXIV gives

the data and Diagram I shows the plotted regression line. If T be the temperature 
in degrees Fahrenheit, A the age in years, the equation to the regression line is: 
T = 98-5915 - -004989 A, 
which indicates that the temperature falls -005 or 200 of a degree per year. The 
problem then arises — can the difference of temperature between the weak-minded 
* Weak-minded epileptics, 98-669 ; criminal epileptics in general, 98-537 ; weak-minded syphilitics, 
98-683 ; criminal syphilitics in general, 98-342. These results are open to the interpretation that the 
weak-mindedness may be owing to cerebral injury due to the disease, and that cerebral disorders are 
more apt than other forms of these diseases to be accompanied by higher temperatures.
