—Mi; Ammomcemh. [October,tubes in which the ovarian follicles should be found, describedby Valentin. At the time in which the sexual differentiationbegins to proceed, and the male germ-glands possess seminalcanals, the ovary is seen to be composed of large bright cellswhich, by reason of very delicate areolar-tissue-partitions andbloodvessels extending from. the hiius to the periphery, arearranged into irregularly-shaped heaps. These germ-cellsSpiegelberg terms primary ovarian cells, and their large vesicularnucleated nucleus he designates "germs.'' During thegrowth of the germ-cell the nucleus divides, at first into two,later on to a greater extent, and the wall of the mother-cell sooriginating appears to he doubly contoured. These mothercellsare the primordial follicles, and are very like the spermaticcells. As soon as they are quite tilled with germ, oneof them, generally the central one, greatly enlarges; andbesides the nucleus, a delicate investment and a granular contentsmay be seen within. The germs surrounding alsoincrease meanwhile and form into cells, and become coveredby an investment. The first of these cells is the ovum, thelast forms the element of the "membrana granulosa." Thus,according to our author, is the formation of the ovum in thehigher animals assimilated to that observed by Meissner inthe ascarides, &c. Soon after birth the formation of germcellsinto primordial follicles is complete, the latter being,later in life, no more formed anew. In newly-born animalsthe younger follicles are always found at the periphery of theovary, the older at the deeper parts. .By the growth of areolartissue and vessels the mother-cells become isolated; veryrarely only do two or more become fused into each other.Ibid.Aramonuvhuo.
