“I have never clearly understood your efforts, and have difficulty in comprehending why you did not turn to the science of the haruspices,” said Pentaur.  “Do you then believe that the changing, and—­owing to the conditions by which they are surrounded—­the dependent life of plants and animals is governed by law, rule, and numbers like the movement of the stars?”

“What a question!  Is the strong and mighty hand, which compels yonder heavenly bodies to roll onward in their carefully-appointed orbits, not delicate enough to prescribe the conditions of the flight of the bird, and the beating of the human heart?”

“There we are again with the heart,” said the poet smiling, “are you any nearer your aim?”

The physician became very grave.  “Perhaps tomorrow even,” he said, “I may have what I need.  You have your palette there with red and black color, and a writing reed.  May I use this sheet of papyrus?”

“Of course; but first tell me. . . . "

“Do not ask; you would not approve of my scheme, and there would only be a fresh dispute.”

“I think,” said the poet, laying his hand on his friend’s shoulder, “that we have no reason to fear disputes.  So far they have been the cement, the refreshing dew of our friendship.”

“So long as they treated of ideas only, and not of deeds.”

And then followed all the old scruples:  that to cut up the heart of a beast even is sinful, because it also is the vehicle of a soul, perhaps a condemned and miserable human soul, which before it can return to the One, must undergo purification by passing through the bodies of animals.  I was not satisfied, and declared to him that my great-grandfather Nebsecht, before he wrote his treatise on the heart, must certainly have examined such an organ.  Then he answered me that the divinity had revealed to him what he had written, and therefore his work had been accepted amongst the sacred writings of Toth,
