Abstract

A SMALL piece of ovary of a very young pigeon was kept for about twenty minutes in a trough of dilute solution of neutral red, just pink in colour (strength—1/25000 physiological salt solution). It was then teased out and examined under an oil immersion lens in artificial light. The young oocytes showed a nucleus and a thick granular mass at one end of the nucleus in the general cytoplasm (C. F. D'Hollander's “yolk nucleus of Balbiani” observed with classical methods). In this area particularly, in more advanced oocytes, could be seen the following three structures (Fig. 1).
