vial on even it if the animal should come from its subterranean home to the light of day the same is true ot of several species of at burrowing animals of the mole and mouse tribes indeed all the vertebrate animals have two eyes vF whether hether they use them or sot not not all an animals emals hime have these two eyes syra metrically placed in the head one on each side certain fishes which apparently par patently enily ly saimon acim on thel the side such as the turbot have both eyes on one the dark side iside of their head that this Is not duo due to a simple 1 twist of the head has been demonstrated by P prof rot elo more athan than twe twenty nty years ago at times by what Is termed arrested development animals and even human beings appear as cyclops or having one cie eye only but who ever heard of a third eye in man or beast and yet recent researches prove that man and all vertebrates vertebrates brAtes seem to possess the rudiments of a third eye 1 y M this di discovery Is not only very interesting td te but also remarkably instructive since the rudimentary third eye of man has hai by one of the most noted philosophers of modern days been looked upon as being the seat of the soul aa organs by proper use develop in strength and perfection BO ao they hey become lack lieck of use if tor for many years an organ without uso its structure in time becomes simpler and more imperfect it if such a process continues through ages an organ by constant disuse mill become reduced to a mere rudiment iu of what hat it was in the species using the same thus species of birds that only walk and run but never gr have only r rudimentary adl wings as the ostrich while in the eagle And the albatross the wings are seen wi state of perfection na now in closely examining the skulls of ca certain iain lizards it was found that near the top of the head bead under the dark opaque skin and often in the very bone an almost perfect eye exists though no say ray of light could ever reach it this eye shows a crystalline lens a retina of very complex structure and an optic nerve in fact all the essential p parts of a pei perfect leit eye but being covered baake by tte opaque skin of the animal it is absolutely useless if this nervo nerve la 14 traced to the brain it is found to connect the eye with the so called pineal gland of the brain the pineal gland Is of course in no sea benso of the word ord a zeal real ZI gland and but a 9 definite portion of the nervo nii dinue of the brain invariably located Just back ind and partly over the cere brner and in front of the round rounded ed brain mass which gene generally rilly ix 3 considered to corre correspond sponA to the corpora quadri gemina semina in man the third eye of the spotted lizard is called the pineal eye 0 on n account of the nerve ne connection of its r retina with I 1 the pineal gland 1 ailein in certain lizards the highl y L aped eye is useless because it opaque skin and in othera even even dee deeply ply bedded in boue bone it f eem probable that in an earlier development this pineal eye iwert rudimentary but in constant use 6 A very ver ar slight modification would accomplish this namely
