The plan adopted for the display of these human mummies--for the Museum contains the preserved remains of the ibis and hawk, the cat, and even the dog, a rare subject for the embalmer, besides the bodies of other inferior animals--is to remove the outer case and covering, then to place the inner case upon the floor; above it, resting on supports, the body; and above that again, the lid, enclosing all within plates of glass, so that the spectator may go round the mummy, examining it in all directions, and likewise the case, within and without, on which the hieroglyphics are inscribed. Before we describe the mummies so laid out, let us explain briefly the process of embalming. Herodotus is a great authority on this matter, and we cannot do better than follow him. In the first place, the embalmer was a medical practitioner, and legally pursued his craft. The deceased was taken to his room, and there the process of preservation was conducted; not, however, till the agreement had been made between the relatives and the embalmer as to the style and cost; for there were three methods of embalming, suitable to different ranks. This having been determined, the operator began, the relatives having previously retired. In the most expensive kind of embalming, the brain was extracted without disfiguring the head, and the intestines were removed by an incision in the side: these were separated and preserved. The body was now filled with spices--myrrh cassia, and other perfumes, frankincense excepted; and the opening was firmly closed. It was now covered with natron for seventy days; and at the expiration of that time, it was washed and swathed in linen cloth, dipped in gums and resinous substances, when it was delivered to the relatives, and by them placed in the mummy case and sarcophagus. It was finally placed perpendicularly in the apartment set apart for the dead; so that the Egyptian could view his ancestors as figured on their coffins; and with the thought that not only were their portraits there, but their bodies also--for the Egyptian was a firm believer in immortality, and piously preserved the body in a fitter state, as he thought, for reunion with the soul, than if allowed to perish by decay. According to the second mode of embalming, no incisions were made upon the body, but absorbing injections were employed. The natron was used as before; and after the customary days were passed, the injected fluid was withdrawn, and with it came the entrails. The body was now enfolded in the cloth, and returned to the friends. This process cost twenty minae, the other was a talent. In the third style, that adopted by the poor, the natron application was almost the only one used; the body lay for seventy days in this alkaline solution, and was then accounted fit for preservation. Sometimes the body, enveloped in the cloth, was covered with bitumen.
