All cases in the Circuit Courts of Appeal, not expressly made final, and in which the matter in controversy exceeds one thousand dollars besides costs, may be reviewed by the Supreme Court by appeal or writ of error. Inasmuch, however, as most of the judgments and decisions of the Circuit Courts of Appeal are declared final (namely, all cases in which jurisdiction is dependent entirely upon the citizenship of the parties, and all patent, criminal, revenue, and admiralty cases) this appellate jurisdiction of the Supreme Court is, relatively, inconsiderable.

15 Act of March 3, 1801. 26 Stat, at L. 826, Chap. 517. Act of Jan. 20, 1897. 2!t Stat. at L. 492, Chap. 68.

16 An "infamous" crime is one punishable by imprisonment in a state prison or penitentiary, with or without hard labor. In re Mills, 135 U. S. 263; 10 Sup. Ct. Rep. 762; 34 L. ed. 107. In criminal cases, in which a conviction has been had in an inferior federal court without jurisdiction the Supreme Court, though without appellate jurisdiction, will discharge on habeas corpus. Bains Case, 121 U. S. 1; 7 Sup. Ct. Rep. 781; 30 L. ed. 849; In re Ayers, 123 U. S. 443; 8 Sup, Ct. Rep. 164; 31 L. ed. 216; Fitts v. McGhee, 172 U. S. 516; 19 Sup. Ct. Rep. 269; 43 L. ed. 535.

The Circuit Court of Appeal may, however, in any case, certify to the Supreme Court any questions of law upon which it wishes the judgment of the Supreme Court; or the Supreme Court may at any time by certiorari or otherwise require a case to be certified to it for review and final determination.
