What meaneth this old dotard, surd and absurd, thus to control our actions?

Do you mean to say that you are not able to tell me what a surd is?

The problems have a surd or irrational element in them; and to solve them would be to bring reason into collision with itself.

We will take them a journey which shall much astonish the venerable Surd.

I was stupefied by surds; and I entered the university.

For Furnace Second were no invitations to Professor Surd's house.

In front of me stood Professor Surd himself, looking down with a not unpleasant smile.

And, therefore, it came that Furnace Second was reduced to zero in Professor Surd's estimation.

Around me were the walls of Professor Surd's study.

Professor Surd was at a faculty meeting.

Under me was a hard, unyielding plane which I knew too well was Professor Surd's study floor.

At length Professor Surd came in.

These 'surds' of metaphysics ought to occasion no more difficulty in speculation than a perpetually recurring fraction in arithmetic.

I mean we granted Surd.

Professor Surd had a daughter.

Abscissa Surd was as perfectly symmetrical as Giotto's circle, and as pure, withal, as the mathematics her father taught.
