There was nothing mysterious about Professor Surd's dislike for me.

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

I will avoid equations, And shun the naughty surd, I must beware the perfect square, Through it young girls have erred: And when men mention Rule of Three Pretend I have not heard.
