is the case with the second and fourth digital lines in the print given 

 here (Fig. 5). 



These difficulties, especially that of the extra-limital position of 

 the digital triradii, certainly prove a barrier towards the application 

 of the same system as in the palm; yet, with some adjustment to con- 

 ditions, this would still seem to be feasible. A diagram assio-ninsf 



numerical designations to the dif- 

 ferent terminal regions is given 

 here (Fig. 7) which may be com- 

 pared with the similar one refer- 

 ring to the jmlm (Fig. 3). 



A more detailed account of the 

 sole formulation is not within the 

 space limit of the present article, 

 but enough has been given to sug- 

 gest how this may be accomplished. 

 I would especially emphasize the 

 practicability of the use of the hal- 

 Incal pattern, perhaps even in a 

 ])rimary classification, which recom- 

 mends itself by its large size, its 

 conspicuous character, and its ready 

 divisibility into definite types. 



Lastl}^, there remains only a 

 short discussion of the means of 

 recording and filing away prints, 

 the amount of space they would 

 occu^jy and their consequent feasi- 

 bility as a means of recording all 

 citizens, as advocated in the previ- 

 ous article. The prints themselves 

 should he taken upon smooth but

(14x81/2 inches) for the hands, 

 and one of 35x28 cm. (14x11 inches) for the feet. Upon each of 

 these the respective prints should be arranged in the natural order, that 

 is, the left upon the left side, etc. There is enough blank paper left 

 in such a piece to record any details necessary about the person; the 

 name, date of birth, nationality, and even the Bertillon measurements. 

 As in the Galton system the formulse may be written at one end, 

 most conveniently the left, so that an especial case coulrl be found by 

 turning over a pile of papers as in selecting a page in a book; or else
