References ............................................... fifty nine topic Index ............................................. sixty five 6 advent The retina as an organ of belief of sunshine, color, form and stream has been the topic of diverse and in depth gentle- and electron-microscopical investigations. so far the curiosity in those has mostly been targeting the constitution of the ma­ ture retina and the genesis of its mobile components. the 1st exhaustive observations at the improvement of the retina in vertebrates have been made by way of Babuchin (1863). utilizing the retinae of fowl embryos, he confirmed that Millier's radial fibres and the ganglion cells are the 1st to enhance, whereas the receptor segments are the final. for this reason, the early differentiation of Millier's radial fibres was once frequently reaffirmed (Cajal, 1893; Meller, 1968; Bhattacharjee and Sanyal, 1975; and others). additionally, Babuchin had already indicated that the structural improvement within the quarter of the posterior pole is particularly fast in comparison with these areas of the retina that are positioned extra peripherally. this day, while evaluating result of electron-mi­ croscopical investigations, this truth is of specific significance, due to the fact that in each one case basically very constrained parts of the retina might be tested. Schultze (1867a, b) mentioned the uniformity of starting place and the overall classifica­ tion of light-perceiving parts into internal and outer segments, therefore contesting the hitherto more often than not held opinion that those constructions, just like the pigment epithelium, ori­ of the attention cup. In 1881 Ogneff came across the analogous ginate from the outer leaf mode of formation in birds and mammals.
