Excerpt from Fly-Fishing and Fly-Making for Trout, Bass, Salmon, EtcThe formation of the eye of the fish does not materi ally difier, one species from another, among the angler's fishes. The cornea is somewhat ¿at in sectional outline, and the shape, or, so to speak, the ground plan, is virtu ally similar in save the European graylin g (s. Thymallus). The pupil of the eye of this fish is oval instead of ciren lar - the oval of the plover's egg rather than that of the hen, being sharper than a true oval at one end. The apex of this sharp end is pointed toward the upper part of the head, tailward, giving the fish a somewhat sinister appearance. What purpose this particular configuration serves I do not know, but one thing is certain The vis ual ability of the grayling is equal, if not superior, to that of the trout, as is proved by its rising, often from a great depth, to the ¿y. I notice, also, that the normal waiting position of this fish is inclined toward the water's surface instead of being horizontal, as is usually the case with trout. This being so, the greater mass of the rays of direct sunlight would fall on the forward part of the eye, and I offer it as a conjecture, based on the law of devel Opment, that this, continued through generations, has evolved the peculiar shape. The graylin g of this country, though apparently similar in every other respect, does not exhibit the peculiarity referred to.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
