Thus we see that the general hospital population is shorter than the average 
of the upper middle classes, approaching closer to the lower middle classes, who 
would chiefly supply the South Kensington Exhibition returns. It is taller than 
the criminal classes either in England or New South Wales, and approaches closely 
to the average of Pearson's " Parent " Group, who must all have been over 40 years 
of age. 
It would accordingly seem that our general hospital population belongs 
anthropometricallj' to a class intermediate between the classes from which criminals 
are drawn and the lower middle class. Its reduced head-measurements are probably 
due in part to this fact, in part to chronic illness, and in part to a concomitant of 
class differentiation, namely want of good nourishment and exercise in the period of 
growth. We might reasonably attribute a great deal to this want of nurture, 
and it seems as hopeless to settle the problem of correlation between size of head 
and intelligence by measuring different social classes, as to settle the correlation 
between stature and intelligence by the same process. 
If we turn to age at death we shall get much confirmation of the view that we 
are dealing with a badly nourished, physicall}' degenerate class. We have
