This is an action of contract to recover the contract price of a series of letters. The facts as disclosed by the pleadings and by the judge’s finding of fact, which it is agreed may be referred to, show that the defendant on March 26, 1920, entered into a contract with the plaintiff, whereby the plaintiff agreed to sell and the defendant agreed to buy eighteen thousand personal service letters, with additional envelopes, at $50 per thousand. *596By the contract the letters and envelopes when delivered were to consist of two sets or series — one, called the “Mothers’ Series,” was for six instalments of one thousand letters each; the other, called “ Department Series,” was for six instalments of two thousand letters each. The letters in each series were dependent upon each other and supposed to be cumulative in making an advertising appeal to prospective customers. They were to be made by the seller especially for the buyer, and were not suitable for sale to others in the ordinary course of the seller’s business. It is agreed that there was but one oral contract of sale for the two series and that the statute of frauds is not a defence. The answer of the defendant is a general denial, unaccompanied by a plea in recoupment.
On May 18, 1920, the first shipment of letters of the first instalment arrived and the defendant on the same day, after examining two or three hundred of them, wrote the plaintiff a letter wherein it complained that many of the letters sent “are so poor that we cannot send them out,” and closed the letter with the statement that “under the circumstances we feel obliged to ask you to cancel the balance of the entire series for both women and mothers.” The plaintiff under date of May 19, 1920, replied: "Thank you for your letter of the 18th with two enclosures. You are justified in your complaint. The work is not up to standard. This may have been due to the limited time in which these letters had to be put through.”
As regards the contractual relation of the parties and the quality of the instalment the judge found “that the first shipment of letters . . . was defective; that the buyer had made known to the seller the particular purpose for which the goods were required, and relied upon the seller’s skill, and that said first shipment was not reasonably fit for such purpose.” Under such contractual conditions of fact there is an implied warranty that the goods shall be of merchantable quality. St. 1908, c. 237, § 15, cl. 1, now G, L. c. 106, § 17, cl. 1. The judge further found and ruled that “the plaintiff’s breach of contract in respect of this first instalment of letters was so material as to justify the defendant in rescinding the contract altogether.” The ruling based upon the finding was right. St. 1908, c. 237, § 45, cl. 2 (see now G. L. c. 106, § 34, cl. 2). After the defendant had learned by *597examination of the letters delivered the nature and degree of the defects in the material quality of the letters, and after it had sent its letter of complaint to and received the reply of the plaintiff, it sent out and used nearly all of the first shipment. In consequence and because of such use of the defective letters the judge found and ruled that “the defendant accepted said first shipment of letters, and actually used nearly all of them for the purpose for which they were intended, notwithstanding their defective quality, and did so with full knowledge of the plaintiff’s breach of warranty, and therefore could not rescind the sale.” This ruling upon the facts found was in accordance with St. 1908, c. 237, § 69, cl. 3 (see now G. L. c. 106, § 58, cl. 3).
The defendant claims that there is no evidence to support any express or implied agreement that the acceptance of the goods shall constitute a waiver of the defendant’s rights. Its request for a ruling to that effect was properly denied. St. 1908, c. 237, § 49 (see now G. L. c. 106, § 38), relied upon in support of the request for the ruling, is not applicable to a buyer’s acceptance and use of an instalment of goods which is defective in quality. Where there is a breach of warranty, express or implied, of the quality of goods delivered in instalments the buyer may elect to accept and receive them as conforming to the contract, or he may receive them and set up the breach of warranty as a defence in whole or in part to the seller’s claim for compensation; or he may return or offer to return the goods to the seller in substantially as good condition as they were at the time they were transferred to the buyer; or he may accept or keep the goods and maintain an action against the seller for such breach. St. 1908, c. 237, § 69 (see now G. L. c. 106, § 58). Hunt v. Brown, 146 Mass. 253, 255. Riley v. Hale, 158 Mass. 240, 246. Gilmore v. Williams, 162 Mass. 351. Cox v. Wiley, 183 Mass. 410.
The defendant’s request for a ruling that “If the goods received by the defendant in the first shipment were of no value to the plaintiff . . . the defendant was not bound to return the goods in order to exercise its right to rescind” was properly refused. It was said in Perley v. Balch, 23 Pick. 283, at page 286: “He [[the purchaser] cannot rescind the contract, and yet retain any portion of the consideration. The only exception is, where the property is entirely worthless to both parties. In such case the return *598would be a useless ceremony, which the law never requires. The purchaser cannot derive any benefit from the purchase and yet rescind the contract. It must be nullified in toto, or not at all. Lyon v. Bertram, 20 How. 149, 155. Skillings v. Collins, 224 Mass. 275, 277.
Sometime in June, 1920, the plaintiff shipped and delivered to the defendant three bundles of letters “of good quality and reasonably fit for the purpose for which they were intended.” These bundles contained two thousand letters second instalment, “Department Series” and one thousand first instalment “Mothers’ Series.” One Hammons, a salesman of the plaintiff, when informed about this time at the defendant’s place of business that the second instalment could not be used, authorized the defendant to return the goods. The goods were returned in October. As regards the statement made by Hammons to the defendant that the goods might be returned, the judge found “that any statement made by Hammons to the defendant to the effect that the second shipment might be returned was made in the mistaken . belief on Hammons’ part, induced by the defendant, without the fault of Hammons or the plaintiff, that said second shipment had been examined by the defendant and found as bad as the first; . . . that said statement did not operate as a waiver of the plaintiff’s rights, and . . . that the defendant did not in fact return said second shipment within a reasonable time after such statement was made.” The judge further found “that when the plaintiff received the defendant’s letter of the 18th repudiating the contract, and notifying the seller to proceed no further therewith, labor and expense of material amount were still necessary on the part of the seller to fulfil its obligations under the contract.”
Because of the acceptance and use of the goods delivered under the first instalment, as also because of the absence of a plea in recoupment, the judge rightly found for the plaintiff in the full value under the contract of the goods so delivered and accepted, with interest from the date of demand to the date of the writ; leaving to the defendant the right to recover damages for the breach of warranty, in an independent action, if it should be so advised. He was also clearly right in ruling and finding as to the remainder of the deliveries under the contract that the plaintiff was entitled to recover only such damages as it would have suf*599fered if it had done nothing toward carrying out the contract after May 19, taking into consideration the profit which would have been made if the contract had been fully performed. St. 1908, c. 237, § 64, cl. 4.
The requests of the defendant, other than those dealt with in the opinion, were rightly refused as not applicable to the facts n 1 pun '
