Note: What acts shall amount to such an acceptance is often a question of great nicety and difficulty. Mozley & W.
Note: In modern law, proposal and acceptance are the constituent elements into which all contracts are resolved. Acceptance of a bill of exchange, check, draft, or order, is an engagement to pay it according to the terms. This engagement is usually made by writing the word “accepted” across the face of the bill. Acceptance of goods, under the statute of frauds, is an intelligent acceptance by a party knowing the nature of the transaction.
