Duplicate Twins and Double Monsters 



[These furnish another case of undoubted duplicates, and the prints would 

 be especially fitted for illustration in this paper, were it not for the fact that 

 they were taken by the twins themselves before receiving proper instruction 

 and are barely sufficient for study, still less for printing. It is also unprac- 

 tical to attempt to procure others in this case. Note the complete symmetry 

 of the two sides in both, as in many of the cases of duplicates, although 

 occasionally found in other individuals.] 



[The finger patterns seem to be all ulnar loops, with no reversal of index 

 patterns.]

[These triplets are made the subject of a detailed study elsewhere and 

 the palm prints are represented in fac-simile in Figs. 8 and 9. It will be seen 

 from these that the difference in the first figure of the formula for the left 

 hands of x and y is apparent rather than real, and that the palms of the two 

 boys are in every respect as " identical " as in the other true cases, while 

 that of the girl {z) is quite unlike them. Again the bilateral symmetry of 

 the lefts and rights will be noticed, a peculiarity not seen in the girl (Z).]

[There is no reversal of index patterns in the two boys; the left index is 

 in each case a tented arch with a loop on the radial side, the right indices 

 are simple ulnar loops.]

[According to personal appearance these should be 

 never seen them, but the one who took the prints wrote: 

 are so similar in coloring, figure and features that even their best friends 

 confuse them." It must be confessed., however, that the differences in the
