delivered tue opinion of the Court. It is an established rule of law, that where, upon the sale of property, the performance of service, or any other transaction, the parties make an express contract for themselves, the law will not raise a promise by implication. Toussaint v. Martinnant, 2 T. R. 100. But here we understand the plaintiff to admit this principle, and to proceed upon the ground of an express promise made by the defendant, that upon the execution of the deed, he would pay the plaintiff the stipulated price, in cash or in stock, according to the terms of their bargain, that the notes were given as security for the performance of that promise, and if from any cause, the notes proved unavailable, he had a right to recover upon this original express promise. But we think this, in several respects, a mistaken view of the case. There must always be a bargain by parol, upon which the sale of real estate is made, as well as in other contracts to be perfected by deed ; but it is inchoate and incomplete, until the execution of the deed. It is unnecessary to rely on the rule of statute law, that all contracts and agreements for the sale of land must be in writing, because in all cases where the parties enter into a negotiation for the sale and purchase of real estate, they know and understand that it is to be consummated by the execution of a deed. Such negotiation and parol agreement, does not change the rights of the parties until the deed is executed; it is that which consummates and carries into effect the agreement of the parties, and vests in them new rights. The transfer of the estate on the one side, and making payment or giving security on the other, are embraced in such agreement and constitute parts of one and the same transaction. Now it is a well settled rule, that all the different parts of the transaction, without regard to the order in which the securities or documents are executed, shall take effect simultaneously, or in such order as shall most effectually execute the Intent of the parties, in the whole transaction. The right to the debt would no more arise without the notes, than the right to the land without the deed. There were not two distinct debts, one arising upon the parol bargain winch *168was discharged by the notes, and another upon the notes. The consideration for the land was the express promise, ol which the notes were the evidence, and then the well known rules apply, that when there is an express promise, the law implies none, and when the evidence of a contract is in writing, it must be produced at the trial. To say that before and independently of the alteration of the notes, the plaintiff could recover, would be to hold that in all cases where, upon a sale of property or other negotiation, a party has promised to pay money, and given his note at the time in conformity with such promise, the holder may still waive the note and sue on such original express parol promise.
If it is said that he is remitted to this right, in consequence of the notes having become void by the alteration, so that the plaintiff cannot recover on them, this is to hold, that a party can acquire a right óf action by his own fraudulent act, in altering his security, to the injury of the other party, an act which the law thus deems fraudulent and in consequence thereof holds the note void, because it tends to the injury of the other party.
If the plaintiff claims upon the notes, he is not entitled to recover, because he has made a material alteration in the notes since they were signed. Master v. Miller, 4 T. R. 320. That it was fraudulent is a conclusion of law from the fact, that it was done willfully, for his own benefit and to the injury of the defendant, by accelerating the payment. It has been made a question, whether the alteration was material. This is easily tested by inquiring whether the notes would have the same legal effect and operation after the alteration as before. After the alteration they were payable on demand ; before it, on time. The difference is apparent. And so the parties understood it. When written “ on demand,” the defendant refused to sign them, and only consented to do so, after the qualifying memorandum was made. But there is no magic in the word memorandum. And it has often been decided, that any words written on an instrument which qualify and .restrain its operation, constitute a part of the contract. Jones v. Fales, 4 Mass. R. 245, where the words “foreign bills ” written in the margin of the note, were held to be part *169of the contract. Springfield Bank v. Merrick, 14 Mass. R. 322 ; Homer v. Wallis, 11 Mass. R. 309 ; Heywood v. Perin, 10 Pick. 228.
The memorandum in the present case had none of the characteristics of a separate, independent and collateral agreement, as in the case of Dow v. Tuttle, 4 Mass. R. 414, but constituted one of the material stipulations of the contract when it was executed.
