¶1The indictment alleges that the defendant “took his corporal oath to tell the truth, the whole truth and nothing but the truth and it is necessary, for his conviction of perjury, that this allegation be substantially provéd. The case cited by his counsel from Peake is authority to show that an averment., describing the form or manner in which the oath was administered, must be proved, or the variance will be fatal. The evidence is that he was sworn to tell “the whole truth and nothing but the truth,” and the question is, whether that evidence supports the allegation. The statute prescribes no form of words for administering an oath to witnesses in court, and is express that no other ceremony shall be deemed necessary in swearing than holding up the right hand; Rev. Stat., chap. 188, see. 10; although in taking depositions it is necessary that the party should be sworn that the deposition contains “the truth, the whole truth, and nothing but the truth.”
¶2There is therefore no doubt that the defendant was properly and legally sworn, in the manner that appears by the evidence, to tell the whole truth, and to tell nothing but the truth relative to the cause. Now it is difficult to perceive any difference between telling the truth and *377the whole truth, and telling the whole truth. The two expressions signify precisely the same thing. It is impossible to tell more truth than the whole truth.
¶3In the case of Rand v. Dodge (ante, page 344), we have held, that where it appeared by the caption that the witness swore that the deposition contained “ the whole truth and nothing but the truth,” it was capable of being amended, because it showed a substantial compliance with the statute, and a state of facts sufficient to justify his certificate to the effect that the deponent had sworn that the deposition contained “ the truth, the whole truth, and nothing but the truth.” ¥e held in that case that the statute required that form in depositions, and that the caption might be amended so as to show it.
¶4We think the evidence sufficient to sustain the allegation in the indictment.
¶5The second objection to the verdict is, that it is not alleged in the indictment that the defendant knew that one part of his testimony was false.
¶6The law on this subject is stated by Hawkins to be, that “ it is not material whether the fact which is sworn to be in itself true or false ; for however the thing sworn may happen to prove agreeable to the truth, yet if it were not known to be so by him who swears to it, 1ns offence is altogether as great as if it had been false ; inasmuch as he •willfully swears that he knows a thing to be trueyvhieh at the same time ho knows nothing of, and impudently endeavors to induce those before whom he swears to proceed upon the credit of a deposition which any stranger might make as well as he. Hawk. P. C., book 1, ch. 69, Perjury, sec. 6.
¶7The allegation in the indictment is, that the defendant swore that he was present at the time Henry George and Thomas Potter exchanged mares, and that the said Henry George did refuse to warrant his mare sound; and that *378the defendant, on the contrary, was not present; that he •well knew that he was n'ot present, “ and that he did not know whether said George so warranted his mare or not.” The material averment is, that he swore to the material fact, and that he did not know whether it was true or not. This seems to be all that is required to bring the act charged within the description of perjury, which consists not only in swearing to material things, known not to be true, but in swearing to them without any knowledge on the subject.
¶8As to the evidence concerning the offer made by the prosecutor, which was ruled out by the court. There is a case in point in 11 Wendell 19. “ Conly was the principal witness for the prosecution, and the counsel for the defendant, upon his cross-examination, offered to prove by him that he had frequently, during the present session of the court, offered to the prisoner that if he would settle the subject matter of the indictment, he, the witness, would leave the court, and not appear again'st him. This testimony was objected to by the counsel, and was excluded by the court. I think it was properly excluded. It could legitimately have had no influence with the jury. It did not tend in the slightest degree to impeach the testimony of the witness, or to show that his narration was not true. Admitting that he had improperly endeavored to Compromise the prosecution, his positive testimony in relation to the fraudulent conduct of the prisoner was not thereby impeached.”
¶9In Harris v. Tippett, 2 Camp. 687, it was held, that questions relating to the conduct of the witness, in connection with the cause or the party, might be asked upon the cross-examination of the witness himself; but that other witnesses should not be examined to the same point, because an issue would thus be raised, collateral to the principal one, and not concerning the rights of the .parties. The matter proposed to be inquired into was an al*379leged attempt of tbe witness to dissuade another from testifying for the opposite side.
¶10We cite these two cases as containing a reasonable and satisfactory illustration of a doctrine, of which it is not easy to derive from the authorities a formula that reconciles all of them. The evidence to which a party is confined is that which is material to the issue. It is material to prove that a witness who testifies is hostile to a party, or has a particular motive for desiring that the verdict should be against him. You may therefore prove, by any competent evidence, that the witness has sworn to be revenged upon the party for some real or imagined injury ; Yeioin’s case, stated by Lawrence, J., in Harris v. Tippett, 2 Camp. 637; or that the witness and the party have a controversy, or the like. 2 Cow. & Hill’s Phil. 730 (in note 509 to page 273); Greenl. Ev., sec. 462. But particular facts and occurrences of such a nature as to create the supposed hostility, or to induce the suspicion of its existence, cannot be proved, except as they may be drawn from the witness himself on cross-examination. They are not conclusive in their effect, and therefore not admitted to be so far material to the issue as to be allowed to become the subject of dispute at the trial.
¶11So far as the tendency of the evidence rejected in this case was to show that the prosecutor wTas urged by sordid motives, it showed that the unworthy motives were removed at the time when he testified. The evidence was not conclusive, certainly, to prove the existence of others.
