[50] Dr. Parkes, in the chapter upon the _Disposal of the Dead_, in 'Practical Hygiene,' evidently leans to the opinion that burial in the sea _might_ suit maritime nations.
A method of petrifaction has lately been broached, and has met with some adherents. Something is to be produced similar to a relic which I once saw for sale in Manchester, taken from a guano-bed about thirty years ago, and which had been interred in the phosphates about a hundred and fifty years previously. In a cave in the Bay of Nipea, a number of bodies were discovered which had been petrified by the waters of some springs. The latest mode of effecting this kind of sanitary preservation was practised upon the body of Mazzini; and the result was, I understand, very disappointing.
A system of inhumation analogous to that practised when stone-coffins were in use is now agitating in Germany.[51] It is proposed to encrust the subject over with a cement, and, after placing it in a sarcophagus of similar artificial material, to pour more of the same matter in a fluid state around it, so that the dead would be entombed in a solid matrix of long-enduring material. But those who are practically acquainted with the nature of cements, or rather with the impossibility of resting assured that proper cements would always be used, will know that it is more than likely that, out of the 32,000 who are said to die annually per million, one-half of the bodies would be enveloped in an impoverished material, which would speedily fall to pieces, with disastrous results. Dr. Sedgwick has expressed himself as certain that even plaster of Paris would prove ineffective in preventing the exhalations from coffins. Supposing, too, that each of the defunct required a space of one cubic yard only, where could cemeteries be obtained which could afford permanently to alienate 32,000 cubic yards of space per million annually? The scheme carries wildness upon its very face. Something analogous to this system of burial was the strange one carried out by the ancient Peruvians. A late traveller[52] has described some of the Huacas, as the places were called, and the well-preserved remains of which are still to be seen. It was a system of piling up coffins of plaster in pyramid fashion, to such an extent that one of these pyramidal mounds measures over 14½ millions of cubic feet. One carefully examined measured over 3½ millions of cubic feet, and was one mass of half-mummified bodies. As fast as a death took place, a chamber of sun-dried material was prepared upon the mound, and the body laid in it; and although the material of which the mound was composed was little else than mud-plaster, these cellular-built Huacas possessed a wonderful power of resistance to decay. One of them, in 1854, had occasion during the war to accommodate a battery of artillery on its summit.
