1. Where an appeal or a writ of error is taken from a District Court or a Circuit Court direct to this court, under section 5 of the act entitled "An act to establish Circuit Courts of Appeals and to define and regulate in certain cases the jurisdiction of the courts of the United States, and for other purposes," approved March 3, 1891, the plaintiff in error or appellant shall file with the clerk of the court below, with his petition for the writ of error or appeal, an assignment of errors, which shall set out separately and particularly each error asserted and intended to be urged. No writ of error or appeal shall be allowed until such assignment of errors shall have been filed. When the error alleged is to the admission or to the rejection of evidence, the assignment of errors shall quote the full substance of the evidence admitted or rejected. When the error alleged is to the charge of the court, the assignment of errors shall set out the part referred to totidem verbis, whether it be in instructions given or in instructions refused. Such assignment of errors shall form part of the transcript of the record, and be printed with it. When this is not done counsel will not be heard, except at the request of the court; and errors not assigned according to this rule will be disregarded, but the court, at its option, may notice a plain error not assigned.

2. The plaintiff in error or appellant shall cause the record to be printed, according to the provisions of sections 2, 3, 4, 5, 6 and 9, of Rule 10.
