Code, § 4-101. “The word ‘agency,’ both in law and as used in every-day affairs, may have various meanings.

(f) It is insisted that the court erred in allowing the amendment to the petition, objected to by counsel for the defendant, and in overruling the general demurrer to the petition as amended. We have, in the statement of the case, set out fully the allegations made in the petition as amended, and they need not be repeated herе. We are of the opinion that, in the light of the principles of law and the authorities cited above in this division of the opinion, the court properly overruled the general demurrer.

Ground 4 of the amended motion for a new trial assigns error on the court’s refusal to grant the defendant’s motion for a mistrial. While the witness E. C. Brannon was testifying on behalf of the defendant, on cross-examination by counsel for the plaintiff, the witness was asked whether or not he had had any conversation with Pethel “regarding this deed to Ed Smith.” Counsel for the defendant objected to the question and proof of any conversation between the witness and Pethel. Thereupon the following colloquy took place in the presence of the jury:
Mr. Royal (of counsel for the defendant): “We intend to connect it up and show that Mr. Brannon didn’t have any confidence in the deed he drew up from Mrs. Merck to Ed Smith.
“The Court: ‘Confidence — in what way?’
“Mr. Royal: ‘That the deed wasn’t any good.’
“The Court: ‘For what reason?’
“Mr. Royal: ‘If you will let me go ahead and I don’t connect it up — it can be ruled out.’
*372 “The Court: No sir- — -I would like to know if you are trying to show Mr. Brannon knew the deed wouldn’t stand up, and if so, what the grounds were.’
“Mr. Royal: ‘We contend that he told Mr. Pethel that the deed wasn’t worth a nickel.’ ”
A motion for mistrial was thereupon made, because the last statement of Mr. Royal was claimed to be prejudicial and made for the purpose of misleading and prejudicing the jury; it being contended that the statement of counsel made in the presence of the defendant was prejudicial to the rights of the defendant because the witness Brannon was the scrivener of the deed from the plaintiff to the defendant, the subject-matter of the litigation, and the effect of such statement was to convey to the jury the impression that such deed was believed to be infected with infirmity and not a valid instrument, and the statеment was surreptitiously made by counsel in order to convey prejudicial matter to the jury. In this ground, it is further contended that this error was magnified later on in cross-examination of the witness Brannon, when counsel for the plaintiff asked the witness if he did say anything regarding the deed to Pethel, and the witness answered that he had a conversation with Pethel, “but I would consider it confidential between attorney and client.”

Woodward

From the record it appears that counsel for the plaintiff sought on cross-examination of the witness to ascertain whether he had a conversation with a person by the name of Pethel, and on objection of counsel for the defendant a colloquy took place between, counsel for the plaintiff and the court. The court, in seeking to ascertain the reason why counsel thought the evidence was admissible, brought from counsel the statement, “We contend that he told Mr. Pethel that the deed was not worth a nickel.” The сhief ground upon which the defendant contends that the court erred in not declaring a mistrial is that the effect of the statement of counsel quoted above was to convey to the jury trying the case the impression that said deed was believed by the scrivener to be infected with such infirmity as not to be a valid instrument. We hold that the court did not err in overruling this ground of the motion for a new trial. The objection to the remark of сounsel for the defendant took place in a colloquy between the court and counsel. The court refused to allow the witness to answer whether he had a conversation with Pethel. The statement by counsel for the plaintiff, that “We contend he told some third person that the deed to Pethel was not worth a nickel,” was not a statement of fact or an assertion that, if the witness was allowed to go into thе conversation, he, the witness, would state that he made such a statement as contended. We cannot say that the defendant was prejudiced or hurt thereby.
*374 Ground 5 complains that the court erred in giving the following charge to the jury: “As a general rule, the injured party must return or offer to return the consideration received for the contract. And that is true in this case, gentlemen, unless you believe, by a preponderаnce of the evidence, that the plaintiff was unable through poverty or other reason, to restore to the defendant the benefit she received prior to the time of filing her petition.”
It is asserted that the charge was erroneous and not sound as an abstract principle of law; that it was confusing and misleading, in that the jury, by the use of the words “or other reason,” were not given any definite limitation of what might be cоnsidered a reason sufficient in law to excuse a tender, and left the jury to apply their own standard of what might be a sufficient excuse for not making a tender.
The use of the words “or other reason” by the court, after instructing the jury that the plaintiff was required to return or offer to return the consideration received under the contract unless they believed by a preponderance of the evidence that through poverty she was unable to do so, while inapt, and not justified under the pleadings, was not such error as demands the grant of a new trial. The evidence disclosed that, in the transaction between the plaintiff and the defendant concerning the conveyance of the property, the plaintiff did not receive directly from the defendant any benefit or consideration at the time the conveyance was made, and that whatever benefits she received from the defendant were services rendered by the defendant, or monetary advances by the defendant, after the deed was made. The deed recited a cash consideration, but the only money that the plaintiff received was $3000, which the defendant- obtained from the proceeds of a loan on the property that the plaintiff had conveyed to him, and this money had been loaned by Gilstrap by virtue of a security deed executed by the defendant to Gilstrap, which, if the plaintiff’s contentions were correct, was in equity and good conscience the property of the plaintiff. The evidence further shows that the defendant had obtained $1000 from Pethel by virtue of a second loan deed the defendant had executed to Pethel conveying the same property. Under the evidence introduced by the defendant, the jury would *375 have been authorized to find that the defendant, either by reason of services rendered, payment of bills, or advancements of money, was entitled to a return of several hundred dollars in money, and by their verdict they allowed the defendant a credit of $500 in this regard, and by decree of the court title to the property was vested in the plaintiff, subject to both the lоan deeds which the defendant had executed to third parties. The jury thereby did not excuse the plaintiff from making restoration by reason of her poverty, “or other reason.” The error in the charge, if any, was harmless to the defendant.
On the general grounds of the motion for a new trial, counsel for the defendant insist that (a) the plaintiff failed to prove her case as laid; and (b) the evidence showed a valid sale of the property by the plaintiff to the defendant. We have set out substantially the evidence in the statement of facts, and will not repeat it here. We have carefully read and reread the evidence in the record, and cannot say that there is not some evidence to support the verdict. Our function is to review the sufficiency of the evidence, and not to determine its weight. Though the evidence might hаve authorized a different verdict
(Stephenson
v.
Meeks,

Ga.

The jury, sitting as triors of the facts, hold the scales that determine the weight of the evidence, and in making such determination they pass on the credibility of the witnesses and adjust conflicts in the testimony, and resolve doubts, and thereby determine which side of the scales, that of the plaintiff or that of the defendant, has the greater weight or preponderance. They are the chemists who distill the facts in order to find the truth. In reviewing their findings, we are not permitted, as judges, to substitute what our judgment might have been if we had participated as jurors trying the case, where all we have before us is'the stenographic report of the trial, and nothing of the warm human drama of the actual trial. The system of trial by jury where disputed legal rights of human beings are settled by the verdict of twelve men, chosen from a list of upright and intelligent men from the vicinage of the parties to the controversy, has been proven by its use over the centuriеs as the best method in arriving at human justice.
