A QUALITATIVE ANALYSIS OF THE EGG-SECRETIONS AND EXTRACTS OF ARBACIA AND ASTERIAS. In corroboration of F. Lillie, it was found that the egg-secretions of Arbacia punclulata exert a chemotactic effect on sperm, and activate, agglutinate, and paralyze by: a sperm +Asterias secretion =dense, angular masses.

This chapter describes the process involved in activation of the egg. Before becoming fertilizable, a terminal oogonium undergoes two principal processes. One is the tremendous growth of the cell, which is mainly because of the accumulation within its cytoplasm of reserve by: For description of the phenomena of agglutination of sperm by egg-extractives of the same species, I must refer to my previous paper (Lillie, a) ; the phenomenon in Arbacia is a true agglu- tination in the sense defined, not a tropistic reaction, nor yet a mass coagulation.
