powerful doses of quinine caused a peculiar throb in my ear which I for some time believed was the sound of somebody continually walking upstairs. Very young children sometimes imagine invisible playmates or companions talk with them, and actually believe that the unseen talk to them in return. I myself knew a small boy who had, as he sincerely believed, such a companion, whom he called Bill, and when he could not understand his lessons he consulted the mysterious William, who explained them to him. There are children who, by the voluntary or involuntary exercise of visual perception or volitional eye-memory, [3] reproduce or create images which they imagine to be real, and this faculty is much commoner than is supposed. In fact I believe that where it exists in most remarkable degrees the adults to whom the children describe their visions dismiss them as "fancies" or falsehoods. Even in the very extraordinary cases recorded by Professor Hale, in which little children formed for themselves spontaneously a language in which they conversed fluently, neither their parents nor anybody else appears to have taken the least interest in the matter. However, the fact being that babes can form for themselves supernatural conceptions and embryo mythologies, and as they always do attribute to strange or terrible-looking persons power which the latter do not possess, it is easy, without going further, to understand why a wild Indian gypsy, with eyes like a demon when excited, and unearthly-looking at his calmest, should have been supposed to be a sorcerer by credulous child-like villagers. All of this I believe might have taken place, or really did take place, in the very dawn of man's existence as a rational creature--that as soon as "the frontal convolution of the brain which monkeys do not possess," had begun with the "genial tubercule," essential to language, to develop itself, then also certain other convolutions and tubercules, not as yet discovered, but which ad interim I will call "the ghost-making," began to act. "Genial," they certainly were not--little joy and much sorrow has man got out of his spectro-facient apparatus--perhaps if it and talk are correlative he might as well, many a time, have been better off if he were dumb.
