156 HARRIS HAWTHORNE WILDER. 



which, from its propinquity to A, might be thought capable of it. 

 Line B, at the lowest position recorded, still keeps within the upper 

 two thirds of the outer (ulnar) margin of the palm, and thus 

 never attains a number less than 5. The known range of line C 

 is between 5 and n, and D always curves up, from position 7 on, 

 save in one rather doubtful case in which it appears to curve 

 downwards and outwards, to reach the outer margin at 5. 



The right hand of the same individual, while closely similar to 

 the left in general appearance, introduces a slight variation in 

 the form of a lower triradius, which confines a number of the 

 ridges of the third interdigital area, allowing line C if one wish to 

 so interpret it, to curve upwards and terminate at position 7, 

 between the ring- and little-fingers. By this interpretation the 

 course of Line C becomes quite normal, and suggests the possi- 

 bility, with a slight rearrangement of lines, of fusing lines B and 

 D, giving the total formula 10-7 -6- 1, which, except for the posi- 

 tion of line A , is not at all unusual. 



This right hand, much like the left but with the profound 

 change produced by the presence of the lower triradius in the 

 third interdigital area, suggests a partial explanation for the 

 wholly anomalous condition of the other side, for in the left palm, 

 at the point corresponding to the lower triradius of the right there 

 seem to be one or two ridges that curve and suggest the last 

 vestiges of a vanished triradius like that of the right. The 

 presence of such a formation in this place might bring about a 

 fusion of lines C and D, making the first two terms of the formula 

 6-8, yet even thus lines A and B are not explained, and remain 

 wholly abnormal. 



Whatever the explanation, the picture presented by these two 

 palm prints, especially the left, with the ridges crossing the hand 

 lengthwise, is strikingly like that exhibited by the large Anthro- 

 poids. This is shown in Figs. II and 12, put into the form of 

 diagrams after the sketches of Kidd (1907; Figs. 48 and 46). 

 Since, however, the figures of this author were drawings from the 

 objects, and not print impressions, and as they were designed 

 to show the relief, including certain of the deepest rugse, it was 

 often difficult to determine the exact course of the ridges, and 

 they are not wholly trustworthy on that account. The similarity
