Mosquitoes are probably another cause — a pre- 

 ventable one. At the present day there are none 

 at Khartoum. Any one found with mosquito larvae 

 in his water jugs, or about the garden premises, is 

 fined. This system has almost entirely eradicated 

 them. 



Chills arising from changes of temperature are 

 difficult to guard against, but a good rule is to put 

 on a light wrap at sunset. All water should be 

 boiled, or better still, distilled. This is a great 

 preventive of illness. At the slightest feeling of 

 chill, or after great fatigue, quinine should be taken. 

 On the smallest attack, remedies should at once be 

 resorted to, so as not to allow the fever to get hold. 



Europeans, on first coming out, think nothing 

 of the sun, and often take liberties. After a few 

 attacks of fever they learn by experience that 

 the sun is not to be trifled with. Young men 

 exposed for long hours to the sun, even with the 

 head well protected, or whose work lies in low-lying 

 ground, will very likely go down with fever unless 

 they take quinine. One official told me he could be 

 out all day long, wading in swampy ground, with 

 no ill effects, as long as he did not fail to take his 

 daily dose of five grains. People with whom 

 ordinary quinine disagrees should try quinine 

 hydrochlor, which is more easily digested. For 

 some people cascara sagrada at night is necessary 

 to counteract the constipating effects of quinine.
