Blind Animals in Caves

Abstract

MR. CUNNINGHAM's notion as to what constitutes “a fact” would appear from his letter published in your issue of March 9 to be peculiar. It is of course only through inadvertence that he declares a mere supposition to be a fact, and states that I have “overlooked” it. His words are “he (Prof. Lankester) has overlooked the fact that blind cave-animals are born or hatched at the present day with well developed eyes.” Further on he proceeds to state that no such fact is known or recorded, but that he is “quite confident” that the young of blind cave-animals have well developed eyes.
