Pktiukied Child.—The Albany Express oays the body of a child which had been buried about six yearn ago, in a private#bury* ing ground in this city, was taken up for in j torment in the Rural Cemetery. The weight of tho coffin attracted attention, and on it* being opened the body was found to bo ]et-rilied. It was white, having the apjiearance of a Plaster Paris cast, and perfect, exceot the head, which had fallen in, and the body was cracked across the center, leaving au opening of about one quarter of an inch in width. Upon slightly striking the body it appeared to be hollow*. It has been convey-I ed to the cemetery.Upon this, the Albany Evening Journal of Saturday, saya:—44 The press of our city, for lotno days past, lias teemed w ith notices of t he body of a child supposed to be petrified. This child died six years ago, and was buried in a clay soil, at Chcrrv Hill. It was disinterred and removed to tho Cemetery ground a few ♦lays since, when it was found as perfect in form as when first buried. We dislike to spoil a cleverly got up story, but we do not look upon this as a matter of jesting, but one rather of a serious reflection. The idea that it is a petrified body, is a humbug of tho grossest character. The subject found has been converted into lt;uUpocere, which is a soft unctuous or waxy substance, of a light brown color, into which the muscular fibers of dead animal bodies are converted, by long immersion in water or spirits, or by burial in moist places under peculiar circumstances.— This substance was discovered by Fourcray, in the burial ground of the Church des la-notrncr, when it was removed in ITS7.— Those desirous of exam ing more fully intothe subject, can do so by referring to the Medical Repository and tho Edinburgh Encyclopedia.
