contained in section 11 (f) of the Federal Register Act as amended (67
Stat. 388; 44 U. S. C. 311 (f)). The contents of the Federal Register
and of the Code of Federal Regulations are by law prima facie evidence
of the text of the original documents and are required to be judicially
noticed (49 Stat. 502, 67 Stat. 388; 44 U. S. C. 307, 311 (e)). The
approved citation of the Code is “CFR.” Thus the citation “14 CFR
40.1” refers to section 40.1 of this title.
