delivered the opinion of the court.

This motion is denied. According to the petition, the court entertained jurisdiction of the cause, but dismissed it for want of due prosecution; that is to say, because errors had not been assigned in accordance with the rules of practice applicable to the form of.the action. This is a judgment which can only be reviewed by writ of error or appeal, as the case may be. Mandamus lies to compel a court to take jurisdiction in a proper case, but not to control its discretion while acting within its jurisdiction. This rule is elementary. Ex parte Morgan, 114 U. S. 174, and cases, cited.

Motion denied.
