Fraternals. 



VII. These prints are fairly similar, as, it may be remembered, their per- 

 sonal appearance is also, all of which may be correlated as a common inherit- 

 ance in which they both have shared, inheriting similar qualities, or a similar 

 combination, affecting all parts of the body. In this connection it would 

 be interesting to note how great may be the tendency towards similarity in 

 palms and soles between two children of different births who closely resemble 

 one another in appearance. 



In detail, the left feet are alike in the hallucal patterns, which form in 

 each case a simple loop; and in the general course of the main lines. There is, 

 however, in y an important 2nd lower triradius, the two upper radiants of 

 which form a broad looped pattern on the 3rd interdigital area, all of which 

 is absent in x, or suggested merely by a convergence of ridges in the position 

 of the missing triradius. In x the 2nd digital line curves downward, enclos- 

 ing the 2nd interdigital area, while in Y this line is normal and the 3rd 

 digital line curves upward. 



In the right feet the hallucal patterns are as in the left, but the relations 

 of the first three main lines become very different through the presence 

 of a 1st lower triradius in y, wholly absent in x. Both have a looped pattern 

 upon the 3rd interdigital area, but the relation to it of the main lines is quite 

 different in the two. 



As these details are hard to follow without diagrams, they may be sum- 

 marized in the statement that the soles are quite similar to one another 

 in general appearance, but possess much greater difference than has yet 

 been observed in either palms or soles of genuine duplicate twins. 



IV. These prints are totally different in every respect; in the general shape 

 the feet of x are long and narrow, while those of y are shorter by 1.4 cm. 

 and much broader. I have never seen the individuals from whom the prints 

 were taken, but am informed that they bear little or no resemblance to each 

 other. 



The sole configuration is of much interest, being as different in the two 

 individuals as was to be expected from the other data. This is seen most 

 strikingly by a comparison of the hallucal patterns. In x the patterns on 

 the two feet correspond, presenting the rather uncommon type of a loop 

 that opens upon the inner margin, enclosed by the incurved hallucal line; 

 in y the two are very different from one another and from those of x, that 

 on the left foot being a spiral with two triradii and that on the right a simple 

 loop that opens upward between the first two digits. The remainder of the 

 foot in y is perfectly featureless, its ridges crossing the base of the foot 

 obliquely, and with a slight convergence towards the inner margin; in each 

 foot of y there is a conspicuous rounded loop over the upper end of the 3rd 

 interdigital arch in which the 2nd digital line participates, and in the right 

 foot there is a hypothenar loop. 



By this comparison it is seen that the complete lack of correspondence 

 in the soles is in perfect accord with the other data, the palms, the 

 finger patterns, and the personal appearance.
