the'hypothenar pattern, indicated by the digit 4. The entire form- 

 ula is thus, in the natural order, 4 5 7 9. In Fig. 2 lines B and C 

 become confluent, so that the termination of each is designated 

 by the number indicating the origin of the other, and the formula 



FIG. 2. Print of a right hand, marked as in Fig. i. Formula: u 10-8- 5. Here 

 the main lines B and C are confluent, and may each be considered to end in the 

 triradius of origin of the other; that is, line B ends in triradius 8, and line C in 

 triradius 10. The third and fourth interdigital patterns are present, the latter 

 with a triradius belonging to it. These features may be added to the formula in 

 giving a complete description.
