•'I am the very pattern of a modern Major-General;
I've information vegetable, animal, and mineral;
I know the Kings of England, and I quote the fights historical,
From Marathon to Waterloo, in order categorical;
I'm very well acquainted too with matters mathematical,
I understand equations, both simple and quadratical,
About binomial theorem I'm teeming with a lot o' news,
With many cheerful facts about the square of the hypotenuse.

I know the scientific names of beings animalculous,
In short, in matters vegetable, animal, and mineral,
I am the very model of a modern Major-General.'
