198 On Criminal Anthropometry 
The extremely close agreement of the results thus obtained in two very 
different ways, especially the agreement in the means, is deserving of special 
attention and is a striking illustration of the value of the new method. 
(12) Application of Methods, continued. I will now pi'oceed to calculate the 
remaining standard deviations, means, and coefficients of correlation. 
Head Length and Face Breadth. See Tables XVI. and XVII., p. 223. 
A = _ -03761; A; = 0; e = -405552, 
•405552 = 6* - 001415?; 
b 
whence 6 = -4055676 and r = -3945 + -0172. 
For s.D. and Mean of Face Bi-eadth : 
?Ji = 1039, Wo = 922, H3 = 1039, /ij = /(j = -39524 ; 
therefore a = 5060216 ± -009856. 
= h^a- = -2000, therefore Mean = 13-45 + "2 = 13-65. 
Head Length and Cubit. Tables XVIII. and XIX., p. 223. 
/t = - 03761, ^■ - - -067734, e - -310452, 
•310452 = 6+ 001274^- - -001^^ + -000529^^ ; 
whence 6 = 3103547 ; r = 3054. 
For s.D. and Mean of Cubit : 
71, = 911, /i2= 1002, ??3= 1087, /i, = -51389, -35224, 
whence o- = 1-96275 ± 0171. 
Also = h^a = 1-00864 ; therefore Mean = 44-05 + = 45-05864. 
Head Length and Foot. Tables XX. and XXI., pp. 223, 224. 
A = --03761, A; = --10295, e = -345875, 
•345875 = e + -001936^- - -002^^ + -000801^^ ; 
whence 6 = '3457144, r = -3389. 
For S.D. and Mean of Foot : 
Wi = 883, 1^ = 979, n3 = 1138, /i, = -540778, /ij = -307234, 
whence a = 1 1792286 + -0103. 
Also Pi = /iio- = -6377009 ; therefore Mean = 25-05 +pi = 25-6877. 
The divisions chosen for Foot are not quite satisfactory, the class " over 26 " 
being too large. 
Having now found the s.D. and Mean of all seven characters, we no longer re- 
quire 9-fold tables, and we shall therefore now use only 4-fold tables in order to 
find r.
