(_Undine counts on her fingers_)

How many?

Undine.

About eight, I think.

Denham.

Try again, stupid!

Undine.

But, father, I think there _ought_ to be ten pence in a shilling.

Denham.

Why _ought_ there, you monkey?

Undine.

Oh, because then, don't you see, you could count on your fingers all
right, but now there are too many pennies for your fingers, and so
you never can tell how many are over.

Denham.

Very convenient. But come now, twelve from twenty-one?
