HISTOCHEMISTRY OF THE OVARY OF FUNDULUS HETEROCLITUS WITH SPECIAL REFERENCE TO THE DIFFERENTIATING OOCYTES

Abstract
The ovaries were studied cytologically and by means of histochemical methods. The succession of appearance of chondriosomes, fat drops, and yolk vesicles, and the formation of intra-vesicular and extravesicular yolk in the growing oocytes, are described. Observations on variations in amt. and distr. of Fe and K, on the plasmal and nucleal reactions, and on the localization and relations of the acid proteins are correlated with the morphological changes in differentiation. Cytosomal differentiations related to food storage are conspicuously chemical phenomena in egg-cells.
