sions as may enter the field of his convenience by nature’s own cali- 
pers—the thumb and fingers—just one more of the advantages which 
the opposable thumb gives man over the ape. This series of measure- 
ments has absolute value at one point of the weapon—that part of the 
haft whichthe hand clutches to render it effective in the blowand secure 
against the shock of impact. Accordingly these measurements have 
been recorded in table 40 in terms of circumference or perimeter, for 
that is the effective system of units.

The nature of the clutch of the hand upon the haft of the club 
remaining constant until receipt of a stunning blow and the relaxation 
of the warrior’s fingers, we can conceive of no grouping of these 
recorded circumferences except in so far as the single-handed grip 
differs from that in which both hands are employed, a difference some- 
what measurable by the length and thereby conditioned weight of 
the piece. We can readily comprehend this difference. In the single- 
handed club the fingers must have such a firm clutch that the haft is 
held in complete approximation to the palm and fingers and the opposi- 
tion of the thumb serves to anchor the clutch. Where both hands are 
used it is not necessary to have the same completeness of clutch, for 
each hand supplements the other in that the two clutches face one 
another. Experiment shows that the critical point of this double
