If sufficient attention is given to this fact, and we consider further, that the thermometrical and hygrometrical conditions of the atmosphere were such in Egypt, that the bodies abandoned to themselves, become dried and formed natural mummies, we shall perceive how vain and unreasonable have been the attempts of those who, for a long series of ages, expected in the middle and northern portions of Europe to embalm human bodies by processes which are only an imperfect imitation of those of Egypt, even in what is defective. Finally, we shall understand how it happens that the sepulchres of the Guanches and Egyptians, yield bodies in such a perfect state of preservation, whilst those of our country offer only bones and dust. Whilst according to the Egyptians the just tribute of admiration which their profound wisdom and extensive acquirements merit, we ought, in a scientific question, to defend ourselves from the infatuation of our predecessors, which led them into error, and appreciate at their just value facts badly observed. We read in the letters of M. de Maillet, “the dry and nitrous earth of Egypt has the property of naturally preserving entire bodies without the aid of any art, especially in those countries at a distance from the Nile. This is a fact which experience does not permit us to doubt. Not long since, there were buried some Frenchmen, in a Coptic church which is in old Cairo, and those who descended the cavern found the bodies of others who had been previously deposited for some time, as perfect as they were the very day that they were inhumed: The clothes even of a Venetian consul, whose corpse had been here interred, were perfectly preserved. I have likewise visited several ancient Mosques, formerly celebrated, but now in ruins, which are situated on the road from Cairo to Suez; these edifices have served as tombs to some Mahommedan kings, whose bodies were here deposited, during the period when Egypt was subject to the Arabs. I investigated some of these caverns, and can assert that I observed bodies so light from desiccation that they could be raised with one hand as easily as if they were a walking stick. Among these bodies, was one which weighed less than four pounds; I saw also a thigh, which, although it appeared entire and full of flesh, with the leg and foot attached, did not weigh one pound. Finally, the same thing is daily observed by the caravans which go to Mecca. There are none of these wanderers who have made this voyage, who could not testify that the bodies of those who die on the route, are dried to such a degree as to become as light as straw.”
