Abstract

It is the purpose of this paper to contribute some information concerning certain cytoplasmic components of the ovum of the goldfish, Carrassius auratus. The writer's primary concern has been the study of the yolk nucleus although some data is given relative to golgi bodies, mitochondria, and yolk. Much already has been written about the "yolk nucleus" of invertebrates and vertebrates but whereas considerable work has been done on the golgi bodies, mitochondria, and yolk of the eggs of fishes, less has been done on the "yolk nucleus" of these forms. Certainly the early work of Balbiani in 1873 (quoted by Henneguy, 1893) .is one of the first to describe this body in fishes. Other definite references to the yolk nucleus of fishes include an excellent article by Henneguy ( 1893), Hubbard ( 1894), Cunningham (1897), Wallace (1904), Munson (1912), Wheeler (1924), Parat (1926), Hibbard and Parat (1927), Hylton-Scott (1928), Mendoza (1943) , and Chaudhary (1949) . Whereas some of the articles (Henneguy, Hubbard, Cunningham, Wallace, and Wheeler) discuss the body at some length, other articles refer only briefly or passingly to the structure.
