At the time of his appearance in Nürnberg, he could walk only with difficulty. He knew no German, understood but little that was said to him, paid no heed to what went on about him, and was ignorant of social customs. When taken to a stable, he at once fell asleep on a heap of straw. In time it was learned that he had been kept in a low dark cell on the ground; that he had never seen the face of the man who brought him food, that sometimes he went to sleep after the man gave him a drink; that on awakening he found his nails cut and clean clothing on his body; and that his only playthings had been two wooden horses with red ribbons. When first found, he suffered much pain from the light, but he could see well at night. He could distinguish fruit from leaves on a tree, and read the name on a doorplate where others could see nothing in the darkness. He had no visual idea of distance and would grasp at remote objects as though they were near. He called both men and women _Bua_ and all animals _Rosz_. His memory span for names was marvelous. Drawing upon the pages of Von Kolb and Stanhope, a writer in _The Living Age_ says that he burned his hand in the first flame that he saw and that he had no fear of being struck with swords, but that the noise of a drum threw him into convulsions. He thought that pictures and statuary were alive, as were plants and trees, bits of paper, and anything that chanced to be in motion. He delighted in whistles and glittering objects, but disliked the odor of paint, fabrics, and most flowers. His hearing was acute and his touch sensitive at first, but after interest in him had lessened, all his senses showed evidence of rapid deterioration. He seemed to be wanting in sex instinct and to be unable to understand the meaning of religious ceremonies. Merker, who observed him secretly during the early days which he spent in jail, declared that he was "in all respects like a child." Meyer, of the school at Ansbach, found him "idle, stupid, and vain." Dr. Osterhausen found a deviation from the normal in the shape of his legs, which made walking difficult, but Caspar never wearied of riding on horseback. His autopsy revealed a small brain without abnormalities. It simply gave evidence of a lack of development. To speak of children who have made the struggle for life with only animals for nurses and instructors is to recall the rearing of Cyrus in a kennel and the fabulous story of the founding of Rome. Yet Rauber has collected many cases of wild men and some of them, taken as they are from municipal chronicles and guaranteed by trustworthy writers, must be accepted as authentic.
