With the localization of the pigment, cytolysis may be seen to be taking place around the clumped granules. The rest of the cortical portion of the egg remains intact. After long exposure, the intact eggs swell greatly, the contents being visibly coagulated and quite free of pigment. Frag- mentation may be observed in some of the eggs in which pigment.
