Duplicate Twins and Double Monsters 



No. XVI.-PAJ.MS [continued). 



In describing the other sets the designations will be arranged in the 

 same relative positions, but the interpretations will be omitted. 



DESCRIPTIVE FORMULA. OF THE PALMS AND FINGERS. 



The list of descriptive formulae is as follows : 



No. I. 



11. 7. 7. 2. S 11. 7. 7. 2. S 



11. 7. 7. 2. S 11. 7. 7. 2. S 



[Notice in these palms the complete bilateral symmetry between those of 

 the same individual. The " S " is a new designation, and expresses the con- 

 dition in which there is neither carpal triradius nor a definite parting of the 

 lines at the wrist, but a seam or break in the direction of consecutive lines, 

 which runs up across the palm, defining the hypothenar area and forming 

 the only element upon which to base the carpal line. The left palms of this 

 set are figured in Fig. 7 and are made the subject of special study later on 

 in the text.]

[Note the reversal of the pattern of the right index, an ulnar fold in one and 

 a radial in the other. Note a similar peculiarity in either the left or right 

 Index of many other duplicate twins, and see the comments below on this 

 point.] 



No. II. 

 P 8. 6. 5. 5. P 



H round loop, rather low. 

 P 8. 6. 5. 5. P 



H round loop, rather low. 

 [These are remarkably similar, and correspond exactly in many little de- 

 tails not apparent in the formulae, as in the general appearance of the 

 hypothenar patterns, the loops enclosed by lines C and D, etc. The single 

 lack of correspondence, that of the first two figures of the left hands, does 

 rot alter the general configuration and in fact I am not sure but what they 

 should really read the same, since the critical spots are covered up by broad 

 red pencil lines, placed there before I realized the value of keeping the orig- 

 inal prints unmarked. 



7. 5. 5. 5. 

 H single broad loop. 



8. 6. 5. 5. 

 H single broad loop.
