โฆ Synopsis
The distribution of actin in sheep ovaries has been examined using immunofluorescent techniques. The germinal epithelium, which contained abundant microfibrils, fluoresced strongly while the underlying stroma was only weakly positive. During early follicular growth a band of fluorescence was associated with the base of those granulosa cells abutting onto the basal lamina. This transitional polarity of actin distribution was correlated with cell shape changes in the basal granulosa.

Dr. C. C . Guthrie ('08) has reported the results of transplanting ovaries from black to white hens and vice versa. A blackplumaged hen furnished by transplantation with ' white' eggs and mated to a white cock gave "about equal numbers of white and spotted" chicks. Guthrie thinks that these black sp
