Ward Hunt, Merchants' National Bank v. Cook…
“ It was the general practice of these parties, as of all bankers in their city, to deal in exchange on New York. The practice was thus: The Merchants' Bank wanted $10,000 to be used in the city of New York. Mr. Homans had the money there, which he did not need for his own purposes. The bank gives him $10,000 in currency, less the difference in exchange, and takes his check on his banker in New York for the sum named. This is the theory of the transaction. In fact, Homans had no funds in New York, but gave his check that he might obtain the currency to be used to meet pressing demands at home. ”
