ABSTRACT
Development of the choroid plexus of the lateral ventricle in rabbit was studied by histological paraffin sections. The choroid plexus is first observed as an invagination from the medial wall of the ventricle at the ninth day of gestation. From the age of 10 days to the age of 13 days prenatally the choroid epithelium is pseudostratified columnar. By the age of 14 days the choroid epithelium starts to present changes from pseudostratified columnar to simple columnar cells. Dark and light can be detected and a large number of metachromatically stained cytoplasmic inclusions at the basal pole can be detected from the age of 16 days prenatally

From this study it could be concluded that: 1. The lens placode could be detected on the 6th day of gestation. 2. The lens vesicle was completely formed by the 8th day of gestation. 3. Formation of the lens fibers started in the central cells of the posterior epithelium as their nuclei were thrown forwards to form the primitive lens fibers. 4. The newly formed lens fibers from the equatorial cells were laid down concentrically round the filled - in lens vesicle
