The "Circuit Court of the United States" was abolished in the Judicial Code of 1911, but in fact it didn't go anywhere as the Repealer only had application on the Revised Statutes of 1878, which is only prima facie evidence of law. The real Judicial Act of 1789 is still intact and I have checked and also Westlaw confirms same. Before the "Circuit Court of the United States" was abolished in the Land of Oz, its powers and duties were transferred into the "District Court of the United States" in the Judicial Code of 1911. Then in the Judicial Code of 1911, the "Circuit Court of Appeals" were created, which in reality are Admiralty and Equity courts and the Writ of Error was abolished in this court in 1928 - i.e. the end of all at law courts in the federal side. In 1948, the Congress in the Land of Oz created the new "United States District Courts" as found today in 28 U.S.C. § 132. Then farther in in 1988 the Congress created a Land of Oz "Writ of Certiorari" that allows the Supreme Court of the United States to pick and choose what cases they want and there is no requirement for jurisdiction or for any issue of merit (substantive issues). Hoo-haa - welcome to the Matrix.
