Diphilus. (Book vii. § 39, p. 458.)

'Tis not my custom to engage myself,

Till first I know how I'm to be employ'd,

And whether plenty is to crown the board.

I first inquire by whom the feast is given,

Who are the guests, and what the kind of fare;

For you must know I keep a register

Of different ranks, that I may judge at once

Whom to refuse, and where to offer service.

For instance now, with the seafaring tribe.
