"Spermatozoa of domestic cock, greatly magnified." The spermatozoam or seminal animalcules, or male Dynamamaebae (figs. 106, 107), are the exact counterparts of ovarian ova, in so far as they are single-celled animals of a very low grade of organization; but their activity and intelligence is marvelousm and still more so is the mysterious attribute with which they are endowed of assimilating their protoplasmic substance with that of the ovum; with the result that thus fecundated ovum is capable of procreating itself by fission for a period until a mass of similar creates in engendered; from which mass is then speedily evolved the complex body the bird."

"The next evolution is presented in Euripides. He is less ideal than his predeccesor, but truer to nature. His drama is more of a reality. He takes his stand in the midst of human life as it is.

He has more variety in his action, greater freedom, more surprises and vicissitudes."—Ridpath, 1885
