— This action is bottomed on tbe provisions of section 1109, Revised Statutes 1899, to recover double damages for an injury to a cow. Tbe evidence was, as we think, quite sufficient to justify tbe submission of tbe case to tbe jury. Tbe court on motion of plaintiff doubled tbe damages assessed by tbe jury and gave judgment accordingly.
Tbe defendant gave in evidence three special acts of tbe general assembly of tbis state relating to tbe North Missouri Railroad Company, to-wit: Tbe act of March" 3, 1851 — Session Acts 1851, p. 483; tbat of January 7, 1853 —Session Acts 1853, p. 323, and' tbat of February 18, 1865 — Session Acts 1865, p. 89. And also tbat it bad by purchase acquired all tbe rights and immunities of the North Missouri Railroad Company by purchase and tbat to tbat extent it now stands in tbe shoes of tbat company. Tbis evidence was introduced without objection. Tbe answer was a general denial only.
Tbe defendant now contends tbat under its said charter provisions it is only liable for one-half of the amount of damages assessed by tbe jury instead of for double tbat amount. Tbe plaintiff, on tbe other band, insists tbat tbis contention can not be upheld for tbe reason tbat no such defense was pleaded in tbe answer of tbe defendant. Defendant replies' tbat tbis defense was proper under tbe general denial.
Tbe acts of tbe general assembly to which we have referred contain no provision declaring them to be public acts and therefore we must regard them as private acts; and before we can notice them they must be pleaded and proved or else pleaded by their respective titles with reference to tbe dates of passage. R. S. 1889, sec. 450; O’Brien v. Railway, 21 Mo. App. 12, and cases there cited; Mexico v. Cauthorn, 25 Mo. App. 285.
*349Under the provisions of section 1109, Revised Statutes 1899, the defendant would undoubtedly be liable to the double damage unless there is some provision of its charter which exempts it from the operation of that section. Busby v. Railway, 81 Mo. 43. These special acts are in the nature of a proviso to said section 1109 and to be invoked they should have been pleaded in one of the ways we have indicated when they would in that have thereby risen to the dignity of public acts, of the provisions of which we could take judicial notice. Bliss on Code Plead., sec. 202. The answer denied the facts alleged in the petition but did not deny liability. The well-settled rule of pleading is: “The defendant, by merely answering the allegations in plaintiffs petition, can try only such questions of fact as are necessary to sustain the plaintiffs case. If he intends to rely on new matter which goes to defeat or avoid the plaintiffs action he must set forth, in clear and decided terms, each substantial fact intended to be so relied upon. If the defendant intends to rest his defense upon any fact which is not included in the allegations necessary to the support of plaintiffs case, he must set it out according to the statute in ordinary and concise language, else he will be precluded from giving evidence of it upon the trial.” Mize v. Glenn, 38 Mo. App. 104; White v. Middlesworth, 42 Mo. App. 368; Guinotte v. Ridge, 46 Mo. App. 254; Hudson v. Railway, 101 Mo. 13; Donovan v. Railway, 89 Mo. 147; Musser v. Adler, 86 Mo. 445.
The defendant did not rest its defense on any fact that was included in the allegations necessary to support the plaintiffs case, but rather upon a provision of its charter in which was contained a partial exemption from liability for the injury complained of. But this provision is not before us in such a way that we can take notice of it. So far as we are advised by the pleadings "the defendant is entitled *350under the law to no right or immunity different from other railway companies in this state. If the defendant by proper allegations of its answer had pleaded its charter then we could have looked at the provisions thereof and have determined the question whether or not it was entitled to the partial exemption now claimed by it; or, in other words, whether or not there was any liability. But the defendant was permitted to introduce in evidence its charter without objection ; still, this did not entitle it to the instruction requested by it to the effect that under its charter rights plaintiff was not entitled to recover double damages. Although the evidence of the existence of the defendant’s charter was given in evidence it was inadmissible under the pleadings and the issues arising on such pleading could not thereby be altered or enlarged. Bank v. Westlake, 21 Mo. App. 565; Wright v. Fonda, 44 Mo. App. 634.
After the defendant succeeded in putting its charter in evidence it should have then requested leave of the court to amend its answer so as to plead the facts which it had had the good fortune to be allowed to prove without objection, and the court in tl 3 exercise of its discretion would probably on terms have granted its request. The defendant so far as-the motion for a new trial discloses took no such step in the trial court and therefore we must dispose of the question as to whether or not it made such request as if not made at all. We can only notice such assignments of error as have for their foundation the grounds specified in the motion for the new trial.
Under the pleadings and evidence given in support thereof the defendant was clearly liable under said section 1109. There is nothing in Daniels v. Railway, 62 Mo. 43, or in Huss v. Railway, 84 Mo App. 111, decided by us at the last April term which would authorize us to disturb the judgment.
*351Tbe defendant further objects that the court erred in permitting a witness for plaintiff, over its objection, to testify his opinion as to whether the cattle guard over which the plaintiff’s cow passed from the public road on to defendant’s inclosed railway track, was sufficient to turn stock. This was improper but later, during the progress of the examination of the witness, the court directed the obnoxious testimony to be stricken out so that the error was corrected by the court itself before any harm resulted therefrom to defendant. Anyway, there was other independent evidence which tended, to prove that the cattle guard in question was insufficient ordinarily to turn stock.
The judgment must be affirmed.
All concur.
