John Marshall,
Spring v. Gray — Opinion of the Court
“ It is no more 'an account,' and no more connected with 'the trade of merchandise,' than a bill of exchange or a contract for the rent of a house, or the hire of a carriage, or any other single transaction which might take place between individuals who happened to be merchants. An entry of it on the books of either could not change its nature, and convert it from an insulated transaction between individuals, into an account concerning the trade of merchandise, between merchant and merchant. ”
