A comparison of Series A with Series B shows that the individ-uals of the latter, the ones w^ith the greater degree of injury, moultsooner than those of the former, the ones with the lesser degree ofmjury. The data for the rate of moulting are collected in TableV in which is given the number of individuals of each series which c.
