Note 178 — Chapter VII · THE ELEMENTARY STRUCTURE OF THE NERVOUS SYSTEM.
Reading edition
On this point consult Axel Key and Retzius, in the Archiv für mikros. Anat., 1873, p. 308, where the nutritive disturbance is assigned to the fact that the lymph can no longer take its normal course. Waller’s observations on the degeneration of the optic nerves, with preservation of the integrity of the retina, after division of the nerves (Proceedings of Royal Society, 1856, p. 10), cannot be urged in support of his view, because Berlin and Lebert’s observations are directly contradictory of his. Saemisch und Graefe, Handbuch der Augenheilkunde, II. 346. It is said by Krenchel that if the nerves be divided, so as to prevent disturbances in the circulation, no peripheral degeneration takes place (cited by Engelmann in Pflüger’s Archiv, 1875, p. 477).
