temperature on pulse rj = -2951 (without corrections) to be compared with 
r = -2865 (without corrections) = -2881 after correction. 
In Diagram IV the weak-minded have been separated from the normal-minded 
criminals and the separate regression lines of temperature on pulse are given for 
both classes. The equations to these lines are: 
For normal-minded criminals: = 97-3651 + -OlSLSP, 
For weak-minded criminals: T,, = 97-9976 + •00708P, 
and the correlations are respectively -2906 ± -0228 and -1847:1: -0471; thus we see 
that there is less correlation in the case of the weak-minded and further that the 
regression lines are no longer, as in the case of temperature on age, parallel. While 
the weak-minded of low pulse-rate have a higher temperature than the corre- 
sponding group of normal-minded, the weak-minded with high pulse-rate tend to 
have equal or perhaps sHghtly inferior temperature to the corresponding group of 
normal-minded. 
(5) On the Correlations betiveen the Physiological and the Physical Variates. We 
have already seen that various points of the physique of these criminals were 
noted by the medical officer. In the first place their capacity for hard labour; 
actually the class of work on which each criminal was employed was given, but 
it seemed sufficient for our present purposes to divide these into hard and light 
labour. In the next place we have the appreciation of muscularity given by the 
two categories muscular and weak. Physical condition was also marked by the 
classification fat and thin, corresponding to good and bad state of nutrition. 
Lastly the general health as appreciated medically was classed as good, indifferent 
and poor. We made the division Good and Not-good, and used in all cases four- 
fold tables, where the bi-serial r was not obtainable. 
The following correlations of the physical characters were reached:

It will be seen at once that these correlations are of a very high order, much 
beyond anything we have hitherto reached. Indeed it is fairly clear that the 
Medical Officer's general appreciation of health or muscularity tallies closely with
