Measurements of Cairo-horn EgyiMans 
excluded for being, at the date when measured, youths of under 20 years of age. 
The remaining 802 individuals providing the final group of measurements dealt 
with throughout the paper are, therefore, adult male Egyptians born in Cairo. 
Of this final group 76 per cent, were measured during 1904-1905, the remaining 
24 per cent, fall within the years 1901 and 1906. 
3. Social class to which the Natives dealt with belong. From the fact that 
these natives have undergone police examination, objection may arise as to 
whether the measurements of such persons can represent the ordinary native 
body, or if really they belong to a selected group of individuals, namely the 
criminal class of natives.

Mr J. I. Craig, writing on the same material, says* "it may be objected that 
criminality in itself is a determinating factor of selection, but the objection does 
not hold in Egypt. Here it cannot be said that there exists a definite criminal 
class, and criminals are rather amateurs than professionals. This state of things 
is in all probability due to the easy conditions under which the lower class live." 
In support of this, I may mention some recent conclusions which Dr Charles 
Goring comes tof. "Criminals as criminals are not a physically dift'erentiated 
class of the general community.. . .The physical and mental constitution of both 
criminal and law-abiding persons of same age, stature, class and intelligence are 
identical.. . .There is no such thing as an anthropological type."
