"Ah!" said Mr. Jellicoe, "that is quite an interesting question. It is not unusual to find mummy cases smeared with bitumen; there is a mummy of a priestess in the next gallery which is completely coated with bitumen except the gilded face. Now, this bitumen was put on for a purpose--for the purpose of obliterating the inscriptions and thus concealing the identity of the deceased from the robbers and desecrators of tombs. And there is the oddity of this mummy of Sebek-hotep. Evidently there was an intention of obliterating the inscriptions. The whole of the back is covered thickly with bitumen, and so are the feet. Then the workers seem to have changed their minds and left the inscriptions and decoration untouched. Why they intended to cover it, and why, having commenced, they left it partially covered only, is a mystery. The mummy was found in its original tomb and quite undisturbed, so far as tomb-robbers are concerned. Poor Bellingham was greatly puzzled as to what the explanation could be."
"Speaking of bitumen," said I, "reminds me of a question that has occurred to me. You know that this substance has been used a good deal by modern painters and that it has a very dangerous peculiarity; I mean its tendency to liquefy, without any obvious reason, long after it has dried."
"Yes, I know. Isn't there some story about a picture of Reynolds's in which bitumen had been used? A portrait of a lady, I think. The bitumen softened, and one of the lady's eyes slipped down on to her cheek; and they had to hang the portrait upside down and keep it warm until the eye slipped back again into its place. But what was your question?"
"I was wondering whether the bitumen used by the Egyptian artists has ever been known to soften after this great lapse of time."
"Yes, I think it has. I have heard of instances in which the bitumen coatings have softened under certain circumstances and become quite 'tacky.' But, bless my soul! here am I gossiping with you and wasting your time, and it is nearly a quarter to nine!"
My guest rose hastily, and I, with many apologies for having detained him, proceeded to fulfil my promise to guide him to his destination. As we sallied forth together the glamour of Egypt faded by degrees, and when he shook my hand stiffly at the gate of the Bellinghams' house, all his vivacity and enthusiasm had vanished, leaving the taciturn lawyer, dry, uncommunicative, and not a little suspicious.
