Histochemical and Morphological Studies of Lipids in the Oogenesis of Pheretima posthuma

A study of the oocytes of the earthworm, Pheretima posthuma, examined fresh under the phase-contrast and interference microscopes as well as by histochemical techniques, has revealed that there are two types of lipid bodies in the cytoplasm. The lipid bodies of the first type (Lj) are smaller, appear as homogeneous, dark granules under the phase-contrast… (More)
