Eldredge delivered the opin- . ion of the court.
Appellant brought his action in trespass on the case against appellee to recover damages for the killing, wounding and worrying of certain sheep of appellant by the dogs of the latter. The jury rendered a verdict in favor of appellee, and from the judgment thereon this appeal is taken.
*155As the judgment must be reversed for errors of law, the weight of the evidence will not be discussed. The third instruction tells the jury that they are the sole judges of the evidence and of the credibility of the witnesses, and, “it is for you to determine from the manner of the witnesses when testifying, the reasonableness or otherwise of their testimony and their means of knowing, if shown by the evidence, and any and all other circumstances tending to aid you in weighing the witnesses’ testimony and determining the weight to which the same is entitled, and if you believe that any witness has wilfully testified falsely, to any material fact in issue, you are at liberty to disregard his entire testimony, except in so far as it may be corroborated by other credible evidence in the case.” This instruction does not confine the jury to the evidence in the case in determining the credibility of witnesses, but permits them to determine this question upon their own ideas of the reasonableness of their testimony and from all other circumstances, whether shown by the evidence or not. Such an instruction permits the jury to determine the credibility of witnesses on matters entirely outside of the evidence in the case. Hartshorn v. Byrne, 147 Ill. 418; Hartford Life & Annuity Ins. Co. v. Gray, 80 Ill. 28; Ames v. Thren, 136 Ill. App. 568; Balenovic v. Ansick, 181 Ill. App. 660; Ryan v. People, 122 Ill. App. 461.
The fourth instruction states that the plaintiff must prove each and every material allegation in the declaration and bill of particulars by a preponderance of the evidence in order to recover. The declaration consists of five counts. Proof of the material allegations in any one of these counts by a preponderance of the evidence would have been sufficient to have entitled the plaintiff to recover. The bill of particulars is no part of the declaration and no part of the record, and controls in no way the weight of the evidence. Its only object is to limit the proof upon the trial to the items mentioned therein,
*156The sixth instruction states, “that if the evidence in this case has not proven by the greater weight thereof the identity of the dog or dogs which caused the injuries to the lambs in question, then in that event of the proof it is your duty to find the defendant not guilty. ’ ’ The principle intended to- be conveyed by this instruction is difficult to determine. In cases of this character there might be ample proof that the dogs of a defendant had killed the lambs of the plaintiff without positive identification of each particular dog which did the killing. There is no law authorizing such an instruction.
The eighth instruction tells the jury, among other things, “but in case you should find for the plaintiff on any one or more of the material allegations of his declaration and bill of particulars, you should do so only where you are convinced of such fact or facts ’by the preponderance or greater weight of the evidence, ’ ’ etc. A jury is only required to believe from the preponderance of the evidence and does not have to be convinced or satisfied by the proofs. Hoener v. Koch, 84 Ill. 408; Gooch v. Tobias, 29 Ill. App. 268; Ruff v. Jarrett, 94 Ill. 475; McDeed v. McDeed, 67 Ill. 545; Crabtree v. Reed, 50 Ill. 206.
The ninth instruction also tells the jury that the plaintiff cannot recover unless he has proven by a preponderance of the evidence the items set out in the bill of particulars.
Instructions 15 and 16 tell the jury that the plaintiff cannot recover for any damages that were not actually occasioned by the dog or dogs which were owned by the defendant. We held in the case of Dole v. Hardinger, 204 Ill. App. 640, that each owner of a dog engaged in doing the damage is liable for the whole amount of the damage done. If two or more dogs engage as a pack in killing or worrying sheep, the owner of any one of the dogs so engaged is liable for the entire damages.
*157. The declaration, charges in each count that the damage was done by two dogs owned by the defendant, and there is some evidence tending to show that one of the dogs was not owned by the defendant. In order to avoid a charge of variance between the allegations and the proofs, leave should be granted to the plaintiff to amend his declaration, if he so desires.
The judgment of the Circuit Court is reversed and the cause remanded.
Reversed and remanded.
