delivered the opinion of the Court.
The appellant was convicted in the Federal District Court for the Northern District of Alabama of a felony and sentenced to imprisonment. The record of the District Court recites that “ a jury of good and lawful men ” was duly empaneled, sworn and charged. After sentence appellant moved to amend the record entry to show that only eleven men sat as jurors in the case and offered testimony in support of the motion. The court rejected the proof on the ground that oral testimony was not admissible to modify or amend the record and, first reciting that after hearing the evidence and arguments and being of opinion that the record of the judgment entry was as it should be and did not need amendment, denied the motion. Appellant then applied to this Court for a writ of mandamus to require the district judge to correct the record in the particulars just stated, setting forth in his petition the evidence offered and rejected. The writ was denied,
Ex parte Riddle,
“ He [appellant] might have saved the point by an exception at the trial or by a bill of exceptions to the denial of his subsequent motion, setting forth whatever facts or offers of proof were material, and then have brought a *335 writ of error. Nolle v. Oyster,230 U. S. 165 , 177. In such cases mandamus does not lie. Ordinarily, at least, it is not to be used when another statutory method has been provided for reviewing the action below, or to reverse a decision of record. Ex parte Morgan,114 U. S. 174 ; Ex parte Park Square Automobile Station,244 U. S. 412 , 414. In this case the facts were more or less clearly admitted at the argument but the record does not establish them and the extent of agreement or dispute with regard to them does not change the remedy to be sought.” Appellant then took the case by writ of error to the Circuit Court of Appeals for the Fifth Circuit, Riddle v. United States,279 Fed. 216 , where the judgment so far as it concerns appellant was affirmed.
The point was not saved in a bill of exceptions, and it was not considered by the Court of Appeals. After the rendition of the judgment by that court, appellant sued out a writ of habeas corpus, in the District Court for the Northern Division of the Northern District of Georgia, seeking release from imprisonment on the ground that the jury which convicted him was illegally constituted of less than twelve men. That court, on the return of the ap-pellee and after hearing, discharged the writ and remanded appellant to custody, from which order the case comes here by appeal.
That the trial court had jurisdiction to try and punish the appellant for the offense with which he was charged is not disputed. The attempt is collaterally tó impeach the record, showing upon its face that a lawful jury was duly empaneled, sworn and charged. Appellant’s remedy, as suggested in the mandamus proceeding, was by writ of error. He did not avail himself of it and whatever may have been Iffie cause or excuse for not doing so,
habeas corpus
cannot be used as a substitute.

The court below was right in ruling that it was without authority to review or set aside the action of the trial court, for, as this Court said in

The order of the District Court denying the. writ is
