(v) Reconstruction of Height from Finger and Foot. 
In this case, 
I- -66084 -73636 
-66084 1- -75871 =-183825, 
-73636 -75871 1- 
i?H= -42436, i?i2 = - -10216 
= -54786, 
TO2= 11-54737, 
R,, = - -23497, 
0-3 = 1-17923, 
m3= 25-68770. 
= -121635, 
•09888, 
0-3= 1-17923, 
mg = 25-68770. 
Therefore the equation becomes : 
166-45716 + 2-8360 (Finger - 1154737) + 3-0304 (Foot - 25-68770), 
and probable error = 2-8651/v'^j. 
(vi) ReconstriiAition of Height from Cubit and Foot. 
In this case, 
1- -79986 -73636 
A= -79986 1- -79099 
-73636 -79699 1- 
= -36481, i?io = - -21299, R,,= 
0-2= 1-96275, 
77(2 = 45-05864, 
Therefore the equation is : 
H = 166-45716 + 1-9198 (Cubit - 45-05864) + 1-4834 (Foot - 25-6877), 
and probable error = 2-5136/Vp. 
(vii) Reconstruction of Height from Finger, Cubit and Foot. 
The A and i2's are already calculated, and from these we can form the equation 
in H. We will however calculate only the probable error, which is 
-67449 X 6-45397 /•03 1586 
Jp V ^6392 
= 2-4919/s/p. 
(viii) Reconstruction of Height from all the other six organs (see formula 
in § 17). 
This formula has not been worked out numerically, but its probable error 
•67449 X 6-45397 /•012129 
5397 /■' 
— V . 
Jp y •038347 
= 2-U82/ Jp. 
We will now collect the probable errors which we have just calculated, taking 
p = 1, which is the case that most interests us.
