employed the plaintiffs to buy and sell for himself individually, and also for the joint account of himself and another, various stocks, bonds, and other securities dealt in on the stock exchange; that the plaintiffs advanced money for making these purchases, and the defendant agreed to leave with them said securities so purchased, or other valuable securities, sufficient to keep them at all times fully indemnified and secured; that for some time previous to J une, 1884, the joint account was in arrears, and the plaintiffs demanded further security and indemnification from the defendant and his copartner, and brought an action against them to recover the amount advanced, which had become due on the joint account; that the defendants duly appeared, and interposed a defense contesting their liability on said account. While such action was pending a settlement of that litigation was made, the plaintiffs agreeing to discontinue the action, and the defendant permitting them to sell the securities held by them both for his individual and joint accounts, and that the proceeds should be credited in one account, and that the advances on both accounts should be also charged in one account, and that such account should be a consolidation of both accounts, and that he would individually assume liability for the balance due on such account after such consolidation, and pay the amount due when he could do so. If this arrangement was not a discharge of the original debt, it is difficult to see how there could be an accord and satisfaction without actual payment. Claims were being made against the defendant and another, which were contested. The plaintiffs held securities which belonged to him individually, and which had been deposited as security for his individual account and the joint account. The contest as to the liability on the joint account is settled by this arrangement, and the defendant permits the securities to be sold. The wording of the complaint, that he requested them to be sold, has no particular significance. The defendant permits the plaintiffs to sell the securities, and in consideration of discontinuance of the action assumes the whole liability, and promises to pay the same when he is able. It is true that this transaction made this an account stated when the accounts were approved by the defendant, as they were, and that, in the absence of any promise to pay, the law would imply a promise. But° where an account is stated, and as part of the transaction an express promise is given to pay upon a condition, that excludes the implied promise, because an express contract to do a tiling excludes the idea of there being an implied contract. For example, when a man purchases goods, arid nothing is said about prices or time of payment, the law implies a contract to pay the value of the goods upon delivery. If, however, the purchaser makes an express promise to pay in 30 days after delivery, what, under such circumstances, becomes of the implied promise? It is clear that it does not arise. So, in the case at bar, if there has been a settlement of these accounts, and simply an account stated had between these parties, an implied promise to pay would naturally have arisen. Butin connection with the settlement is an express promise upon the part of the defendant to pay when he is able. That is the condition upon which lie consents to the accounts and to the sale of the securities, and upon which he withdraws his defense to the joint account. Flow, after the plaintiffs have accepted the withdrawal of the defense and the sale of the securities, and have accepted the assumption of liability by the defendant, it seems to be difficult to see how they can escape the condition upon which that liability was incurred. In other words, they propose to have the benefit arising from the settlement relieved from the burden which was specifically attached to it. The mere fact that the account was duly admitted correct by the defendant himself does not deprive him of the conditions with which that admission was coupled.
It is urged, however, that, assuming the appellants to have agreed to forbear, where is to he found the consideration sufficient to support so important an agreement? The consideration seems to be apparent, and the whom ques
