a slight saline efflorescence with a base of soda. Mummies which have been only salted and dried, are generally more badly preserved than those in which are found resins and bitumen. “Many varieties are met with in these last sort of mummies; but it appears that this is due to the want of care and negligence of the embalmers in their preparation. Some, still entire, have the skin dry, white, smooth, and stretched like parchment; they are light, inodorous, and easily broken; others have the skin equally white, but a little supple; having been less dried, they have assumed a fatty state. We find also in these mummies, masses of that fatty, yellowish matter, which naturalists call _adipocere_. The features of the face are entirely destroyed, the eyebrows and hair have fallen; the bones become detached from their ligaments without any effort, they are as white and clean as those of a skeleton prepared for the study of osteology; the cloth which envelopes them, tears, and falls to pieces at the slightest touch. These sort of mummies, commonly found in particular caves, contain a considerable quantity of saline substance, which I have ascertained to consist almost entirely of sulphate of soda. The various species of mummies of which I have just spoken, are swarthed with an art which it would be difficult to imitate. Numerous linen bandages, several metres in length compose their envelope; they are applied one over the other, to the number of fifteen or twenty thicknesses, and thus make several revolutions, first around each member, then around the whole body; they are so compact, and interlaced with so much address and skill, that they appear to have endeavoured by this means, to render to these bodies, considerably reduced by desiccation, their original form and natural thickness. “All the mummies are enveloped nearly in the same manner; there is no other difference than the number of the bandages which surround them, and the quality of the linen, the tissue of which is more or less fine, according as the embalming was more or less precious. The body embalmed, is at first covered with a narrow chemise, we find only one large bandage enveloping the whole body. The head is covered with a piece of square linen cloth, of a very fine texture, the centre of which forms a species of mask; five or six are thus found sometimes applied one upon the other; the last being generally painted or gilded, and represents the figure of the person embalmed. Each part of the body is separately enveloped by several bandages impregnated with resin. The legs brought together, and the arms crossed upon the chest, are fixed in this position by other bandages which envelope the whole body. These latter, generally loaded with hieroglyphical figures, and fixed by long fillets which traverse each other with much art and symmetry, finish the envelope.
