Description:Excerpt from Proceedings of the Academy of Natural Sciences of Philadelphia, Vol. 68 In this note it was shown that following ingestion Of the so-called spores of this parasite, penetration Of the intestinal cells of the mouse was effected within about two hours. Once within the cells the Spores rapidly underwent profound changes and after the lapse Of about. Nine hours they had separated into two categories, which were interpreted to represent males and females. In the case Of the supposed males, development took the form of a loss of most if not all Of the cytoplasm, so that the parasite became reduced to a nucleus, which, however, was Of considerably larger size than that Of the original spore. Later, the chromatin Of this nucleus became col lected into a number Of small rounded masses placed at the periphery. These masses, at first granular, later became solid and eventually transformed themselves into elongated, thread-like bodies, which were interpreted to be microgametes. This evolution was completed at the end Of 18 hours. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
