The celebrated David Hartley was very instrumental in procuring this grant to Joanna Stevens. He obtained also a private subscription to the amount of L1,356, published one hundred and fifty-five _successful_ cases, and, by way of climax to the whole, after eating _two hundred pounds weight_ of soap! David himself died of the stone. AN IMPOSTOR. From the Testament of Jerome Sharp, printed in 1786:--"I entered," says the narrator, "with one of my friends, and found a man resembling an ourang-outang crouched upon a stool in the manner of a tailor. His complexion announced a distant climate, and his keeper stated that he found him in the island of Molucca. His body was bare to the hips, having a chain round the waist, seven or eight feet long, which was fastened to a pillar, and permitted him to circulate out of the reach of the spectators. His looks and gesticulations were frightful. His jaws never ceased snapping, except when sending forth discordant cries, which were said to be indicative of hunger. He swallowed flints when thrown to him, but preferred raw meat, which he rushed behind his pillar to devour. He groaned fearfully during his repast, and continued groaning until fully satiated. When unable to procure more meat, he would swallow stones with frightful avidity; which, upon examination of those which he accidentally dropped, proved to be partly dissolved by the acrid quality of his saliva. In jumping about, the undigested stones were heard rattling in his stomach." The men of science quickly set to work to account for these feats, so completely at variance with the laws of nature. Before they had hit upon a theory, the pretended Molucca savage was discovered to be a peasant from the neighbourhood of Besancon, who chose to turn to account his natural deformities. When staining his face for the purpose, in the dread of hurting his eyes, he left the eyelids unstained, which completely puzzled the naturalists. By a clever sleight of hand, the raw meat was left behind the pillar, and cooked meat substituted in its place. Some asserted his passion for eating behind the pillar to be a proof of his savage origin; most polite persons, and more especially kings, being addicted to feeding in public. The stones swallowed by the pretended savage were taken from a vessel left purposely in the room full of them; small round stones, encrusted with plaster, which afterwards gave them the appearance of having been masticated in the mouth. Before the discovery of all this, the impostor had contrived to reap a plentiful harvest. PERUVIAN BARK.
