At McGill University Hospital,1a one case of carcinoma of the trachea was observed in 9,000 autopsies; at Montreal Hospital,1a one case in 12,700 autopsies; at Johns Hopkins University Hospital,1a Baltimore, no case in 15,000 autopsies; at New Haven Hospital,1a New Haven, Conn., no case in 3,900 autopsies; at Philadelphia General Hospital,1b two cases in 25,000 autopsies; at Charity Hospital,1b New Orleans, one case in 23 years; at Los Angeles County Hospital,1b no case in 12,000 autopsies; at Cook County Hospital,1b Chicago, one case in 545 cases of carcinoma, and at Guy's Hospital, London,1b no case in 5,000 autopsies.
