Ordinates, agglutinating units. Abscissae, duration of experiment, in days. Charcoal Adsorption.—Equal weights of animal charcoal, previ- ously washed and dried, were added to equal quantities of a series of dilutions of egg-water whose agglutinating power was known. The charcoal egg-water mixture was shaken and then filtered through filter-paper, and its agglutinating power again tested against the same sperm suspension. The filtrate was colorless, and had lost from 90 to 100 per cent, of its agglutinating power, indicating a high adsorption coefficient. (See Table VI.) Both echinochrome and fertilizin had been adsorbed. (In this connec- tion see also Glaser, '21 a.) It will be seen that relatively more fertilizin is adsorbed from samples of egg-water which have been diluted. The data for the.
