PROFESSOR KARL PEARSON, MATHEMATICAL 
My mean error is only 3‘7 centims., however, as against Maxcuveier’s 9'3. Allowang 
for the doubtful character of some of these measurements, I consider this result 
fairly satisfactory, and believe my estimate may in several cases be better than the 
supposed stature.

(23.) Dwarf Races. 
(a) Concerning the curves I have given, much diversity of opinion must naturally 
exist. For we have made use of giants from a great variety of races in order to pro¬ 
duce across a considerable range of stature the regression curves based upon the data 
for one local race, the French. The justification for this can only be post-facto, 
namely, the capacity of the curves to predict the stature of giants and dwarfs satis¬ 
factorily. But it Avill be seen that in doing this Ave hav’e proceeded rather on 
mathematical than anatomical grounds. We haAm supposed a continuity between 
the normal population and betAveen giants on the one hand and dwarfs on the other. 
We have treated these beings as rare Amriations in a normal population, and not as 
pathological abnormalities. It is true our curves show a region of marked instability, 
AA'ithin AAdrich any slight change of long bone is accompanied by a great change in 
probable stature ; but nevertheless we haAm supposed a mathematical continuity, 
Avhich in itself is hardly consistent Avith the theory of “ pathological abnormality.”
