In presenting this paper I will limit its scope to the pathologic conditions found, and to the bacteriologic work done with the cultures obtained from the cases of yellow fever at the Isolation Hospital, principally to corroborate the claims of Sanarelli.
The pathology comprises the examination of urine and the blood, the autopsies and the bacteriologic research of Sanarelli's bacillus icteroides.
There were 348 specimens of urine and 154 of blood examined, and 51 autopsies were held. The 154 specimens of blood represent as many patients from whom blood was taken and examined. The examinations of urine were made as they generally are in the pathologic department of the Charity Hospital, only they were made oftener as a guide in the treatment of the cases. Albumin was found in all the cases of yellow fever during the course of the disease. It usually appeared before the fifth day, seldom after.
