and then distributed by means of pipes. The disease may also 

 be spread by infected sewage or infected water coming in 

 contact with oysters and other shellfish, or with vegetables, 

 especially when these are eaten raw. The practice of using 

 liquified human excrement as a manure or as an insecticide in 

 vegetable gardens, and especially in growing salad vegetables, 

 is suspected of being a fruitful source of typhoid fever. 



The linen or other textiles which come into contact with a 

 typhoid patient have been reported as having spread that 

 disease ; therefore, this should always be rendered sterile as soon 

 as it leaves the patient. This is best done by steam under pres- 

 sure, but where that is not available, the textiles may be 

 immersed in a 1 to 1,000 bichloride solution contained in 

 wooden vessels, a 6 per cent carbolic solution, or a 1 per cent 

 kreso solution. 



The common house fly is also involved in the spread of typhoid 

 fever, and the itinerary of this insect pest from the manure heap 

 or closet to the pantry has only to be remembered to under- 

 stand how its evil work in this regard is done. 



SUMMARY. 



Probably one of the greatest services we can render the 

 people of the Philippine Islands is to set ourselves assiduously 

 to the task of preventing the further spread of typhoid fever and 

 of eradicating that which is already here. In order that we may 

 know, then, just to what extent our communities are infected, 

 a blood specimen should be sent to the Bureau of Health in every 

 suspected case. This will insure accurate diagnosis and enable 

 a systematic study of the disease to be carried out, as well as 

 intelligent application of measures for its eradication. 



In closing, I desire to thank you for your attention, and 

 earnestly ask that you lend your hearty cooperation, in order that 

 the useless sacrifice of lives may be avoided and our highest 

 ambitions as physicians realized.
