We report to-day our conclusions regarding a series cases of typhoid fever at an altitude of about 5,000 feet, in order to compare the disease as we see it with typhoid fever in general.

There occurred 225 cases in the private practice of Dr. Hall in Colorado, 54 of these being seen in consultation; 292 cases, most thoroughly recorded and analyzed by Dr. Claude E. Cooper, Denver, late house physician at the Arapahoe County Hospital, occurred in the wards of that institution between 1896 and 1902. We include only 12 of the cases seen by Dr. Hall in his service at St. Anthony's Hospital, the records of cases at this institution for several years being too incomplete for inclusion. He did not personally see all of the cases reported from the Araphoe County Hospital, and he here tenders his thanks to his colleagues for permission to use the hospital records.
