This is an indictment for adultery, to which a motion to quash was filed, on the ground that it does not conclude against the peace of the Commonwealth nor against the statute in such cases made and provided. This motion was overruled, and the defendant alleged exceptions. The Pub. Sts. c. 213, § 16, expressly enact that no indictment shall be quashed on this ground, if the omission does not tend to prejudice the defendant. But it was argued that the statute is unconstitutional. We shall not consider how far the Legislature might go in simplifying indictments before encountering Article XII. of the Massachusetts Bill of Bights. We admit that there are limits to its power in this direction; that, for instance, it could not authorize the omission of allegations necessary to describe a specific crime. Commonwealth v. Harrington, 130 Mass. 35. State v. Learned, 47 Maine, 426, 433. McLaughlin v. State, 45 Ind. 338. Hewitt v. State, 25 Texas, 722. But there is no doubt that it can do a good deal in the way of simplification. Commonwealth v. Bennett, 118 Mass. 443. State v. Corson, 59 Maine, 137. State v. Comstock, 27 Vt. 553. Brown v. People, 29 Mich. 232, 237. We do not think that it needs argument to show that the Legislature may dispense with a purely formal averment which would give the defendant no additional information, and the omission of which would not prejudice him. Commonwealth v. Holley, 3 Gray, 458. “ Technical and formal objections of this nature are not constitutional rights.” Commonwealth v. Hall, 97 Mass. 570, 574. See Commonwealth v. *67Davis, 11 Pick. 432, 438; Stockwell v. Silloway, 100 Mass. 287, 295. The defendant was safe in assuming that the proceeding was under the statute, although he was not informed so in terms. Galizard v. Rigault, 2 Salk. 552; S. C. 2 Ld. Raym. 809. 6 Dane Abr. 676. Commonwealth v. Call, 21 Pick. 509, 511. Commonwealth v. Elwell, 2 Met. 190, 191. Anderson v. Commonwealth, 5 Rand. 627, 632. State v. Cooper, 16 Vt. 551. State v. Brunson, 2 Bailey, 149.

Exceptions overruled.
