Plasmata

"Certain recent observations on the maturation of the ovum are of great interest in this connection, as illustrating the possible mechanism by which ovogenous plasma in the extrusion of the first polar body, and a number of ancestral plasmata in that of the second, are removed from the nucleus of the ovum; the former process being designed to equalize in bulk the ovogenous and germinal plasmata contained in the nucleus (Aequations-theilung), the latter to reduce the total number of ancestral plasmata present by a half (Reduktions-theilung)."
