Attempts have been made in the Rat, Rabbit, Hedgehog, Ferret and Xenopus toad to trace degenerating fibers into the hypothalamus after division of one optic nerve. No evidence was found of a retion‐hypothalamic connection. This finding is not in accordance with the results reported by several others who made comparable experiments; and it is suggested that confusion may have arisen because neuro‐secretory nerve fibers taken for degenerating hypothalamic pathways.
