Rufus Wheeler Peckham, Price v. United States (165 U.S. 311…
“ No one denies that there are degrees of obscenity, any more than that two and two make four; but, when a book is stated to be so obscene that it would be offensive if set forth in full in an indictment, such allegation imports a sufficient degree of obscenity to render the production nonmailable and obscene under the statute.This indictment is sufficient, because it does, in fact, contain a charge that the book was obscene, to the knowledge of the defendant, who knowingly and willfully, with such knowledge, deposited it in the mail, and thus violated the statute. ”
