This house was kept closed during the daytime and had a temperature of from 92° to 95° F. It was occupied for twenty nights by three American volunteers, and the test was repeated twice Dr. James Carroll, and Dr. Jesse W. Lazear, and they were assisted by a Cuban, Aristide Agramonte, who had recovered from the disease and was therefore immune. A camp was established in which two cottages were erected. In one of these the ventilation was intentionally very poor. In the other there was a mosquito-tight screen separating the two halves, and the ventilation was very good.
