Were the " 7.5 " of x changed to 8.6 as may well be possible, we would 

 have another case of the complete bilateral symmetry in the hands of each 

 twin as in the case of No. I.]

[Here the patterns of the left index are reversed, although it is not notice- 

 able at first, since the pattern in question belongs to the arch type, normally 

 bilaterally symmetrical. By a careful examination, however, the arch is seen 

 in each case to bear a small loop along one side, the loop being radial in one 

 and iilnar in the other. This I have indicated by the little letters used as 

 exponents.]

[Reduced tracings of these palms were published in Amer. Jour, of Anat., 

 Vol. I., pp. 436-437, and show their complete identity. While in one way no 

 nearer alike than are the two preceding sets, there are more special features 

 to be copied and the duplication is thus very complete, and more striking. 

 The twins themselves, who are young ladies of twenty, had long noticed the 

 curious patch of cross ridges on their left palms which represents a rudi- 

 mentary " thenar," or morphologically a first interdigital.]

The palms represented by these formulae are very unlike in general appear- 

 ance. The high position of C in ic-left gives to that hand an especial char- 

 acter as that condition always does; and shows a marked contrast to the 

 condition of the corresponding palm of y. The twins of this set do not at all 

 resemble one another and are undoubtedly fraternal.]
