This indictment is upon St. 1864, c. 122, § 4, which provides, among other things, that “ whoever sells or keeps or offers for sale adulterated milk, or milk to which water or any foreign substance has been added,” shall be punished by a tine as therein specified. The defendant contends that the Commonwealth should have been held to prove on the trial that he committed the offence knowing the milk to be adulterated. But the language of the statute does not require such proof; and it is evident that the legislature did not intend tho* it should do so. The St. of 1863, c. 140, required such proof, and one of the reasons which induced the legislature to repea. it and substitute the existing statute for it undoubtedly was that they regarded it as impracticable in most cases to prove the knowledge, and that they also regarded it as reasonable under all the circumstances that the seller of milk take upon himself the risk of knowing that the article he offers for sale is not adulterated. It is of the greatest importance that the community shall be protected against the frauds now practised so extensively and skilfully in the adulteration of articles of diet by those who deal in them, and if the legislature deem it important that those who sell them shall be held absolutely liable, notwithstanding their ignorance of the adulteration, we can see nothing unreasonable in throwing this risk upon them. It is the same risk which every man takes who sells intoxicating drinks ; the law making him liable to the penalty, although it is not proved that *491he knew that the liquors were intoxicating. Commonwealth v. Boynton, 2 Allen, 160. This construction of the statute is confirmed by the fact that some of the offences mentioned in it must be committed knowingly; and are thus expressly distinguished from the offence alleged in this case.
It is further contended that the proof of knowledge is neceasary, because it is alleged in the indictment that the defendant sold the milk knowing that it was adulterated. But this averment, not being material, is to be rejected as surplusage.
It is further objected that it is not alleged or proved that the milk was cow’s milk. But as the statute does not mention cow’s milk, it must be held to include all the milk of commerce, and this objection is therefore groundless.
It is further objected that there is a variance between the allegation that the milk was sold to Bridget Donegan, and the proof that in making the purchase she acted as the agent of her husband, he being the legal owner of her stock in trade. But it did not appear in evidence that the defendant had any notice, express or implied, that she acted as the agent of any person, and it is settled that when a purchase is made by an agent, of whose agency the seller has not sufficient notice, express or implied, the sale may be regarded in law as made to the agent, and so it may be alleged in an indictment. Commonwealth v. Kimball, 7 Met. 308. Commonwealth v. Remby, 2 Gray, 508.
It is objected that the indictment is bad for duplicity, because it alleges that the defendant sold “ adulterated milk to which a large quantity, to wit, four quarts of water, had been added.” It is contended that the selling of adulterated milk, and the selling of milk to which water had been added, are two separate offences. But such is not the true interpretation of the statute.
The mixing of water with milk offered for sale adulterates the milk by adding to it a substance of less value, and the indictment describes in this count a single offence only.
Exceptions overruled.
