 by the periodicity of disease. For months, and 

 possibly for years, the symptoms recur so regu- 

 larly that even Europeans will use evacuants 

 and quinine two or three days before the new 

 and full moons. In such cases, I repeat, change 

 of climate is the best aid to natura curat rix. 



The malignant typhus is rare at Zanzibar : it

 ship wrecked on the northern end of the island, 

 when the men were long exposed to priva-

 yellow fever, have cured malignant, inveterate, and chronic 

 cases. The Persians at one time in Zanzibar besieged Colonel 

 Hamerton's door for this ' Ab-i-hayyat ' — water of life. The 

 invaluable wet sheet and the Turkish bath were unknown at 

 Zanzibar in 1857.
