A comparison of Table II. shows that the criminal is younger and less variable 
in age than the General Hospital Population. To test the effect of the more 
youthful population, we omitted the criminals less than 26 years of age. The results 
were as follows for head length of 916 cms. : 
Mean Age : 37-46 ± '21. Standard Deviation : 9-52.54 + -1498. 
Maximum Length : 191-73 + -14. Standard Deviation : 6-1534 + -0968. 
Correlation of Age and Head Length : + -1062 + -0220. 
Clearly the correlation is not sensibly affected, while the age is sensibly and the 
mean head length slightly raised. We think we must conclude from this result
