urine, stools and sputum. Soiled linen, the bath 

 water of typhoid patients, the remnants of food 

 and drink, and the eating utensils should be dis- 

 infected before removal from the room. Nurses 

 or attendants should not eat or drink in typhoid 

 rooms. 



Hexamethylenamin may be of value in causing 

 the disappearance of bacilli from the urine, and 

 the advisability of using the drug as a routine 

 measure for public safety is worthy of con- 

 sideration. The room should be kept free from 

 flies and eventually it should be disinfected, pref- 

 erably by formalin. During an epidemic, in case 

 the water supply of a community is susceptible to 

 contamination, all water used for drinking, wash- 

 ing of vegetables and eating utensils, should be 

 boiled, and that used for general cleaning may be 

 otherwise disinfected. The possibility of dust in- 

 fection of a house should not be disregarded. 



The typhoid carrier remains one of the difficult 

 problems of prophylaxis. That carriers may be 

 rid of bacilli by inoculation with dead bacilli, has 

 not been satisfactorily demonstrated except in 

 some instances. Systematic detection and treat- 

 ment of these carriers is hard to carry out. 



There are two methods of specific prophylaxis serotherapy 

 against typhoid: 1, the injection of antityphoid ?i n . 

 immune serum; 2, preventive inoculation with 

 killed cultures of the bacilli. Antityphoid serum 

 confers a fairly strong and immediate immunity 

 which, however, is of short duration, because of 

 the rapid elimination of the serum. Its use as a 

 general preventive, therefore, is not advocated.
