The Life and Opinions of Tristram Shandy, Gentleman

An eye is for all the world exactly like a cannon, in this respect; That it is not so much the eye or the cannon, in themselves, as it is the carriage of the eye -- -- -and the carriage of the cannon, by which both the one and the other are enabled to do so much execution. I don't think the comparison a bad one; However, as 'tis made and placed at the head of the chapter, as much for use as ornament, all I desire in return is, that whenever I speak of Mrs. Wadman's eyes (except once in the next period), that you keep it in your fancy.

I protest, Madam, said my uncle Toby, I can see nothing whatever in your eye.
