covers it with his hand when it falls on the table. He looks up at
Potiphar_.

POTIPHAR. Much depends on this. What shall I say?

JOSEPH. I know what you will say, sir.

POTIPHAR. Impossible! Tails.

_Joseph uncovers the coin. Potiphar bends over it_.

JOSEPH. (_without looking_) It is heads.

POTIPHAR. So it is! I lose--Joseph, you are a lucky man!

JOSEPH. Not at all, sir--a clever one. You see, I knew just how the
coin would fall. I tossed it so that it would fall that way.

POTIPHAR. But--how did you know what I was going to say?

JOSEPH. I will explain to you. On one side of the coin is a
representation of the present Pharaoh, who has denied you advancement
because of his daughter's interest in you. In consequence, you
dislike any reminder of him--even on a coin. But on the other side is a
representation of the goddess Isis; she is your favourite goddess--and
moreover, you yourself have been heard to remark that her face and
figure resemble remarkably that of a certain great lady, whose name--is
never mentioned when the story is told. Naturally I knew how you would
call the coin.
