The above arrangement shows that while pairs Nos. 1, 2, 
3, 4, 5 are not very well matched, pairs Nos. 6, 7, 8, 9, 10, 11 
are excellently well matched. 
In two instances the individuals are separated by three 
types (1st and 2nd pairs). 
In three instances the individuals are separated by two 
types (3rd, 4th, and 5th pairs). 
In three instances the individuals are of adjacent types 
(8th, 10th, and 11th pairs). 
In three instances the individuals are of the same type 
(6th, 7th, and 9th pairs). 
A particularly suggestive fact is that pairs Nos. 7, 8, 10 
should have matched so well, seeing that they were all taken 
* The three pairs 7, 8, 10 were taken within a few yards of each 
other at the same time and date.
