[As may be supposed, these boys are in every way identical. The slight 

 discrepancy in the right carpal formula, a triradius (C) in a; and a parting 

 (P) in 2/ is very likely an error, since in a print one cannot distinguish be- 

 tween a genuine parting and the lines which diverge to form a triradius that 

 occurs below the limit of a print. In fact it is a question whether or not all 

 genuine partings are to be interpreted as the beginnings of " extra-limital " 

 triradii, or those which would be formed by the imaginary continuation of the 

 ridges beyond the limits of the friction skin. Neither palm possesses any 

 special features other than those indicated in the formulae.]

[There is here no reversal in either set of indices, but the right hands show 

 a difference in the pattern of the middle finger, a condition not seen in any 

 of the other cases of genuine duplicates.]

[These twins caused me some little difficulty, although they show by the 

 formulae great differences and determine the set as fraternal beyond a doubt. 

 The subjects are little girls of ten, whom I have seen but once, and at the 

 time I took it for granted that they were duplicates, and, as they came to my 

 laboratory hand in hand, dressed exactly alike and each with her hair in 

 two small braids; they were certainly similar, but to my assistant they did not 

 appeal in the same way, and she judged them fraternal before seeing the 

 prints. There is a noticeable difference in height and quite a little in weight, 

 greater than is usually found in true duplicates.]

[The finger patterns of both are mainly of the whorl type, but even here 

 y is at variance with her sister in two digits, which possess ulnar loops.] 



No. XI. 

 11. 9. 7. 5. C 11- 9. 7. 5. C 



A curious loop on 4th interdigital A rudimentary L\ which forms a 



^rea, perhaps accounted for as an lenticular figure, made by a parting 



inverted 1'. of the ridges. 



11. 9. 7. 5. C 11- 9- 7- 5. C 



The curious loop, identical with A rudimentary l^ forming an 



that of ^-left. exact duplicate of the figure of 



a?-right.
