On May 30, 1904, the defendant, through its president and secretary, gave plaintiff’s agent the following order for telephones:

S. O. Pederson, Sec.

Terms to be cash 30 days after installation.

This agent testified that a certain warranty appearing in plaintiff’s printed catalogue was read to defendant’s directors' at the time the order was taken, and that it was given as a part of the order. This warranty reads as follows :

Guarantee.

Material and work guaranteed against inherent defects.

If any part or parts prove defective through any fault of this factory, such part or parts will be cheerfully repaired or replaced without charge, regardless of time that may have elapsed from date of purchase.

All apparatus fully warranted to give satisfaction in the work for which it is designed, when properly installed.

No risk incurred in buying Chicago telephones.

This factory guarantees every part as well as the complete instrument without any time limit.

In this way purchasers are protected by the Chicago Telephone Supply Company, the largest and strongest factory in the world devoted to the production of bridging telephones.

Defendant contends, however, that the sale was by sample, and that as a part of the transaction plaintiff’s agent orally warranted the telephones to be as good and would work as well as any on the market, and that if the phones were not entirely satisfactory to defendant company and its patrons, plaintiff would take them back and that there would be no sale. It also pleaded that plaintiff promised to give *255a written warranty corresponding in terms to the oral one with each phone. It alleged that the phones did not correspond with the sample, were not as good, and would not work as well as those of other manufacturers on the market; that they were not satisfactory to defendant and its patrons; that a large number of them failed to work; and that plaintiff failed to furnish the written warranty as promised, and that for these reasons it tendered back the telephones and rescinded the contract. Plaintiff pleaded the written warranty in the catalogue as being the only one it made, and averred that it offered and at all times stood ready to comply with the terms thereof, but that defendant .failed to do its part and improperly installed the instruments. The case was submitted to the jury on these issues, resulting in a judgment for defendant.

1. Warranty: pleading estoppef. Plaintiff contends that the court was in error in permitting the introduction of parol testimony tending to show the terms of the warranty, insisting that there was either no warranty, or that it was in writing, and that parol testimony was inadmissible either to establish a warranty or the terms thereof. As plaintiff expressly admitted in its reply that -there was a warranty, it does not now lie in its mouth to say that there was none.

2. Proof of parol waranty. Moreover, the memorandum of sale taken by the agent does not purport to be a full and complete contract,, and there is nothing therein which would exclude parol proof of a warranty. Such testimony would in no manner contradict the order. Grant v. Frost, 80 Me. 202 (13 Atl. 881); Shambaugh v. Current, 111 Iowa, 121; McCormick v. Richardson, 89 Iowa, 525.

3. Parol warranty: question of fact. This being time, and the written warranty upon which plaintiff relies not being made a part of or inserted in the contract, it became a parol one, although the ’ f . . °. terms were expressed m print m the printed ■Lm x catalogue. Under such circumstances it became a question of fact for the jury to determine whether *256the warranty was the one found in the catalogue or one by word of mouth. The trial court so instructed, and as to this there was no error. The jury evidently found that the warranty was in accord with defendant’s contention, and there was evidence sufficient to sustain this position and also sufficient to show a breach thereof, and we shall not disturb the findings.

4. Contracts: rescission. It is the rule for this State that a contract may be rescinded for breach of warranty. Wernli v. Collins, 87 Iowa, 548; J. I. Case Co. v. Haven, 65 Iowa, 359, and many other cases which might be cited. And this is true, although the contract be sever-able, provided the breach goes to the entire consideration. Another rule is that the parties may provide their own remedies and procedure in case of breach. This, according to defendant, they attempted to do, and it is said that one remedy was rescission of contract for substantial failure of the phones to work satisfactorily. Various rulings are complained of in the reception and rejection of testimony, and to some of these we shall now give attention.

5. Examination of witnesses discretion. II. The cross-examination of one of plaintiff’s witnesses is complained of. This is a matter resting so largely in the sound discretion of the trial court that a very flagrant disregard of the rules must be shown to justify us in interfering. That does not appear here, and there was no error of which plaintiff may complain. Indeed we think the cross-examination related to matters inquired about in chief, and that it was within the well-known rule relating to this subject.

6. Offer proof reduction to writing. Objection being sustained to certain questions propounded by counsel for defendant to some of its witnesses, counsel stated before the jury what he expected to prove by such witnesses. This was objected to by plaintiff’s counsel. As to one of the witnesses the statement was simply introductory and without any prejudice whatever, for it was essential to *257enlighten the court as to defendant’s claims. As to the other witness, McCoy, defendant’s counsel, stated in substance, after objections had been sustained to some questions propounded by him, that he expected to prove by witness that the company of which he, witness, was secretary, purchased some of the same kind of phones that plaintiff sold to defendant, under like warranties and guaranties, that these phones were installed as defendants were, that they failed to work, and that upon notice plaintiff removed them. The court denied defendant a right to show these matters. While it would perhaps have been better for the court to have required this statement to be put in writing, yet plaintiff’s objection was not put upon this ground. And nowhere was the court asked to strike it out, or to direct the jury to disregard it. In view of this record, there was no error in the proceedings of which plaintiff may justly complain. Defendant’s counsel had the right to enlighten the court as to what he expected to prove by the witness, and unless objection was made to the oral statement thereof before the jury there was no error in not having the matter reduced to writing.

7. Objection to proceedings, While counsel excepted to the proceedings, he gave no reason therefor, and under well-known rules the court was justified in disregarding the objections. After the statemerd tad been made, plaintiff’s objection to .¿kg offered testimony was sustained, and the jury was thus in effect instructed to disregard it.

8. Exclusion of evidence: harmless error. Wlile plaintiff’s agent was negotiating the sale through defendant’s board of directors, he presented to them, so it is claimed, a written recommendation signed by the treasurer of another telephone line to the effect that the telephones supplied by plaintiff for their lines were giving satisfaction and that he believed them equal to any telephone made, that they would ring and talk as far as any of equal size, and that the company would do as it agreed. This, he testified, was *258read to every director present. This recommendation was offered in evidence, but defendant’s objection that it was incompetent, hearsay,' and not rebuttal, was sustained. Of this ruling complaint is made. As bearing upon the question as to whether or not defendant relied upon the warranty given, this paper might well have been received in evidence. For any other purpose the statement was incompetent and hearsay. But as the witness, who conducted the negotiations, was permitted to state without objection that he read the guai*anty contained in the catalogue to defendant’s board, “ and offered as evidence that our property was giving satisfaction a recommendation from the Burkman people ” [referring to the written letter of which we have spoken] there was no error. It need not appear that the warranty was the sole inducement for the sale. Even though to some extent he relied upon his own judgment or the statements of others, he may, nevertheless, rely upon a warranty, if that were one of the inducements to the sale. Forcheimer v. Stewart, 65 Iowa, 593; Powell v. Chittick, 89 Iowa, 513. As the witness who made the sale for plaintiff admitted the making of some kind of a warranty and simply produced the letter of recommendation as evidence that plaintiff’s phones were giving satisfaction, there was no prejudicial error in excluding the letter itself. In no event could it have had any relevancy, save as it bore upon the question of defendant’s reliance upon the warranty, and as to this plaintiff admitted that some kind of warranty was given to be relied upon by defendant’s agents, and the only question was the nature and extent of that warranty. The trial court instructed the jury that it must find that defendant’s agents relied upon the warranty to make it binding upon the parties. The record is such that no prejudice resulted from the exclusion of the letter.

*2599. Demonstrativeevidence: discretion. *258Plaintiff asked that it be permitted to make tests of the phones in the presence .of the jury under conditions which it claimed closely assimilated those existing where the *259phones were to be used by defendant, but the court would not permit it. The universal rule is that it is within the discretion of the court to permit .. . . n p , such experiments m the presence oi the jury. Such real or demonstrative evidence should not be permitted, unless the conditions are substantially similar, and this is a matter for the determination of the trial court. With its discretion and judgment thereon appellate courts rarely interfere. Elliott on Evidence, section 1252; Ulrich v. People, 39 Mich. 245; Lake Co. v. Wugg, 132 Ind. 168 (31 N. E. 564). Other rulings on the admission and rejection of testimony need not be considered, as they were either correct or clearly without prejudice to appellant. .

10. Sales breach of warranty: rescission. III. Defendants tested but fifty-two of the one hundred and four phones shipped it, and found each of these, as it claims, worthless. -It never opened or tested the remaining fifty-two phones, and plaintiff claims that the contract was severable, and that un^61, any ^ggry 0f the case j-fc was entitled to recover the purchase price of the fifty-two phones which were not tested. It ashed an instruction to this effect which was refused. In lieu thereof the trial court gave the following instructions: “ 34. It appears from the evidence that the phones ordered under the contract in question in this case were to be used in extending the lines of the defendant company, and it appears from the evidence that uniformity was desirable in the instruments to be thus installed. Under such facts and cirumstances as are shown in the evidence in this case, the defendant company had the right to reject the entire number called for in the order without installation or test of the remaining phones, if the fifty-two phones installed and tested were rightfully rejected under the rules given you in this case.”

This ruling presents the only debatable question in the case. On its face the order for the phones was severable, and the failure of one or more less than the whole to com*260ply with, an ordinary warranty would not justify an entire rescission of the contract. Dibol v. Minott, 9 Iowa, 403; Spear v. Snyder, 29 Minn. 463 (13 N. W. 910). The record in this case, however, is peculiar. Fifty-two of the phones were never unpacked, received, or used by the defendant. Defendant installed fifty-two of those shipped it by plaintiff, and found that they would not work. It then notified plaintiff of the failure of the phones to work, and that it would not install any more until plaintiff remedied the defects in those in place. This was not done, and after waiting a reasonable time for the remedying of the defects, defendant rescinded the sale and offered to return all the phones. It is practically agreed that the phones were all alike and of one make, and according to the contract defendant had the right to rescind in case of breach of warranty. Under these facts there was no error in refusing the instruction and in giving the one asked. The breach of warranty affected the entire consideration, and in view of plaintiff’s testimony that the phones were of one make and similar in all respects defendant did all that was required of it when it found that the fifty-two phones which it installed did not comply with the warranty. When plaintiff failed to make the phones already installed work in accord with the warranty after notice of the defects, defendant was not bound under this record to install the other phones to see if they would not work. The phones were purchased for use as a system, and defendant could not be held liable under the evidence for a single phone which might happen to work.

IV. Lastly, it is insisted that the verdict is without support in the evidence, and that there should have been a verdict for plaintiff. This was a jury question, and with its finding we are not disposed to interfere.

The record presents no prejudicial error, and the judgment is affirmed.
