pattern only, which occasionally occurs in this region, and which, when 

 present, defines the territory below it as 3 and that above it as 5. A 

 line entering it and returning along its lower side would be designated 

 as 4/3 (Fig. 4:, d), one emerging above as 4/5 and one that becomes 

 involved in the pattern and does not emerge is simply 4. 



When a pattern is not present 

 in this region, 3 may signify ap- 

 proximately the lower third of 

 the entire outer margin, and 5 

 the remainder. 



In the majority of cases a 

 main line will terminate in one 

 of three ways, it will either 

 (1) open freely along the outer 

 margin; (2) cut through an in- 

 terspace between fingers or (3) 

 it may fuse with another main 

 line, forming a loop. In this 

 latter case each of the two lines 

 involved may be considered as 

 terminating in the triradius of 

 origin of the other and be described by the corresponding number. 

 Aside from these three possibilities, there is an occasional fourth 

 one produced by the presence of what may be designated ^ lower iri- 

 radii.' So" far as has actually been observed (in above 600 hands) 

 these may occur in but two places, as designated in the diagram (Fig. 

 3) by inverted Is in tbe 2d and 4th of the digital interspaces (count- 

 ing that between the thumb and the first finger as the 1st), but 

 there is morphological ground for expecting one also in a correspond- 

 ing position in the 3d interspace. When a main line terminates 

 in one of these triradii it should be designated by a 1, with an ex-

 scriptive formulae. Compare with Fig. 7.

ponent signifying the space to which the J. belongs ; thus 1 '^ or ± 

 as the case may be. In addition to these, pattern triradii may occur 

 in connection with the thenar and hypothenar patterns, and of these 

 the second, 1^'^, comes into occasional relation with line A. 



Having now a method by which the course of the four main lines 

 may be designated by means of a sequence of four figures, let us illus- 

 trate this by a few cases taken at random, and represented by the 

 tracings given in Fig. 4. 



For these the main line formulae will be as follows:
