The imperfections of these methods grow out of their very nature. Along side of these embalmings, practised in an empyrical manner, without any reference to the qualities more or less efficacious, of the aromatic and balsamic substances, I can place infants several months old, subjects most susceptible of dissolution, _and which, after a simple injection, have remained exposed to the air in a moist room_. At the end of two years of this exposure, they displayed a great suppleness of the tissues, without the least trace of decomposition. Those which I enclosed in cases, in the midst of an atmosphere of my own discovery,[E] have preserved exactly the expression and colour of the face, that they had at the moment of death. [E] This atmosphere, we have reason to believe, consists of the vapour of oil of turpentine. We examined some of these specimens, which, after a simple injection with the solution of the acetate of alumine, were exposed to a current of air, and found them as hard as horn and somewhat distorted.--_Tr._ CHAPTER II. NATURAL MUMMIES. Whilst man agitates and torments himself in employing all his activity to produce a feeble result, nature, all-powerful, by means of simple causes, produces wonderful effects. Man disputes with the rivers, the ocean’s waves, some few acres of land, which he protects with great labour from their overwhelming influences. At the voice of nature, elements, until now foreign to each other, approximate, combine, and unite in the bosom of the earth, and suddenly throw up from the middle of the ocean vast isles and new continents. He has need of all his industry to make the sap circulate in a few etiolated plants; she, on the contrary, confers life and motion to all beings, or strikes them with torpor or death, according as she elevates or depresses the sun a few degrees in the horizon. In order to preserve the bodies of his own image, man, stimulated by sentiments of religion, respect, or of love, mutilates in vain their inanimate spoils; in vain he penetrates with aromatics and preservative juices, remains, which putrefaction reclaims and seizes. Nature covers with a little snow the traveller who scales the mountain, then, after centuries, returns the body unaltered. She commands the winds to blow: the sands of the desert are agitated, and the soldiers of Cambyses, and the soldiers of Alexander, are dried in the dust; penetrating with some unknown bodies the entrails of the earth, she there preserves the generations which have preceded us.
