A comparison of the specific amounts of regeneration at the 
end of fifty-one days shows on the whole an advantage in favor 
of the individuals with the greater injury. In the undetermined 
species the specific amounts of regeneration of the shorter chela 
are 0.83, 0.88 and 0.96 respectively for the three individuals with 
both chela removed and 0.86 for the one individual with the 
shorter chela alone removed. In the case of the larger chela the 
specific amounts when both chela were removed are o. 7130-73 
and 0.76 in the three individuals against 0.69 in the one individual 
with the longer chela alone removed.
