f bed on a winter's night to do an emergency operation
at a hospital? He doesn't get paid for it. Do you think it is altruism?"

"Yes, of course. Isn't it?"

"Certainly not. He does it because it is his job, because it is his
business to fight with disease--and win."

"I don't see much difference," she said. "It is work done for love
instead of for payment. However, I will do what you ask if the
opportunity arises; but I shan't suppose that I am repaying your
kindness to me."

"I don't mind, so long as you do it," I said, and we walked on for some
time in silence.

"Isn't it odd," she said presently, "how our talk always seems to come
back to my uncle? Oh, and that reminds me that the things he gave to the
Museum are in the same room as the Ahkhenaten relief. Would you like to
see them?"

"Of course I should."

"Then we will go and look at them first." She paused, and then, rather
shyly and with a rising colour, she continued: "And I think I should

enigmatically; a very soft laugh, low-pitched and musical, like the
cooing of a glorified pigeon.

I strolled on by her side, speculating a little anxiously on the coming
introduction. Was I being conducted to the lair of one of the savants
attached to the establishment? and would he add a superfluous third to
our little party of two, so complete and companionable, _solus cum
sola_, in this populated wilderness? Above all, would he turn out to be
a comely young man, and bring my aerial castles tumbling about my ears?
The shy look and the blush with which she had suggested the introduction
were ominous indications, upon which I mused gloomily as we ascended the
stairs and passed through the wide doorway. I glanced apprehensively at
my companion, and met a quiet, inscrutable smile; and at that moment she
halted outside a wall-case and faced me.

"This is my friend," she said. "Let me present you to Artemidorus, late
of the Fayyum. Oh, don't smile!" she pleaded. "I am quite serious. Have
you never heard of pious Catholics who cherish a devo
