The preceding recitals have been the subject of numerous commentations, discussions, and researches. It is astonishing that Herodotus has omitted desiccation; but it naturally took place during the time consecrated to preparation. Some assert that the body was in the first place salted, and subsequently penetrated with resinous and balsamic substances, which, incorporating with the flesh, prevented putrefaction: others pretend that the body, after having been salted, was dried, and that it was not until after this desiccation that the resinous and balsamic substances were applied. A simple inspection of the mummies is sufficient to reject the first opinion. What union, indeed, could these last named matters have contracted with the fluids of the tissues? and how can we conceive from thence, that bodies often filled with corrupted serosity, could have resisted the intestine effects of such active causes in producing decomposition? M. Rouelle thought that the _natrum_ was a fixed alkali, which acted after the manner of quick-lime, despoiling the bodies of their lymphatic and greasy fluids, leaving only the fibrous and solid parts. Thus viewing in this manner the Egyptian process, it removes an error into which Herodotus has fallen on the subject of the first class of embalming. It is there stated, that they filled the belly of the corpse with myrrh, canella, and other perfumes, except _incense_, and that afterwards they put it into the _natrum_ and then washed it. But of what use would have been these resinous matters, with which the alkali of the _natrum_ would soon form a soapy mass, which the lotions would have carried off, at least, in great part? It is much more reasonable to suppose that these balsamic and resinous substances were not applied to the bodies until after they were withdrawn from the _natrum_.
