After walking through swamps, see that the skin is well 
rubbed with a rough towel or flesh brush. All drinking 
water must be filtered. 
Internal Treatment.—Nitrate of potash in 2 dr. doses given 
in butter-milk is said to cure guinea-worm in from three to 
five days, and the application of electricity to the worm- 
affected part may cause its death. Assafcetida in 5 to 15 gr. 
doses daily for a week has cured many cases. It is said also 
that feeding a patient on sugar-candy for twenty-four hours, 
without any other food or drink, may cause the death of the 
worm. 
Extraction of the Worm.— After securing the worm, 
attempts should be made to extract it every twenty-four 
hours. As much as 6 or 8 inches a day may be extracted 
and wound upon the quill, which should then be fastened 
parallel to the limb with two pieces of strapping, and the 
part dressed with lint soaked in a solution of alum, 8 grs. to 
the ounce. This prevents the part becoming dry, and also 
strengthens the worm, and so tends to diminish the danger of 
its breaking. The natives are very skilful in extracting the 
worm by making an incision over it and rapidly turning it 
out, but this requires great skill. 
Constitutional symptoms, when they arise, must be treated 
on general principles, and if malaria complicates matters, 
the use of quinine must be energetically pushed. 
Egyptian Chlorosis. 
This disease is common in Egypt. It is caused by the 
ingestion of the Anchylostomum duodenale, from which it is 
reported that a fourth part of the population suffers. It is 
said to be a stage in the development of the Dochmius trigono- 
cephalus of the dog. It attaches itself to the lower portion of 
the human duodenum and jejunum. The symptoms caused 
by the presence of this worm are those of pernicious anzmia. 
For debilitated individuals it may prove fatal in a few weeks. 
In well-fed persons the disease may exist for two or three 
years. It is found that the best treatment to get rid of the 
worms is the administration of the milky juice of the Micus
