1. Eggs of Urechis caupo were exposed to infra-red light of wave-lengths from 0·7 to 2·0µ. 2. Upon subsequent insemination the rate of cleavage and sometimes also the proportion of the eggs forming fertilisation membranes was reduced. 3. This effe

A study has been made of the effect of near infra-red radiation on the subsequent fertilization of the eggs of some marine invertebrates. The species studied were 2 sea urchins (Strongylocentrotus purpuratus and S. franciscanus) and a worm (Urechis c
