The Complete English Tradesman by Daniel Defoe

There are some businesses which are more particularly accustomed to partnerships than others, and some that are very seldom managed without two, three, or four partners, and others that cannot be at all carried on without partnership; and there are those again, in which they seldom join partners together.

Mercers, linen-drapers, banking goldsmiths, and such considerable trades, are often, and indeed generally, carried on in partnership; but other meaner trades, and of less business, are carried on, generally speaking, single-handed.
