for at least one hour; then thrown into the closet, 
buried, or burned. In the country they should be 
thrown into a trench so placed that the surface drain¬ 
age is away from the well or the nearest water course. 
Quicklime should cover the stool in the trench and 
over this dirt should be thrown. The urine should be 
disinfected with carbolic acid solution in the same 
manner. All urinals and bed-pans must be disinfected 
with carbolic solutions after being used. 
The patient should have eating utensils and toilet 
articles for his own exclusive use, which should be 
marked and kept separate from all others. Remnants 
of food should be burned or disinfected away from the 
kitchen. 
Nurses and attendants on typhoid patients must 
always wash their hands after handling the patient in a 
i: 1000 solution of bichloride of mercury. Uniforms 
and linen that have been worn in the patient’s room 
should be soaked in carbolic solution before being 
taken to the laundry. Nurses should not eat in the 
same room with typhoid patients. The direct infection 
from patient to nurse is not at all uncommon, and the 
directions just given must be strictly observed. 
After recovery the patient should be given a full 
bath before leaving the room, and the room itself dis¬ 
infected in the usual way. Chronic carriers should be 
isolated and every effort made to render them non-in- 
fectious.
