common form of malaria, the destruction of 
the corpuscles takes about two days; so the 
chills and fever are felt every other day. The 
use of quinine cures malaria, because it kills 
the microbes in the blood. 
We can protect ourselves against this microbe 
by the use of screens and netting to keep 
mosquitoes from biting us. They should also 
be kept from biting a person who has malaria, 
for the microbes in the blood then get back 
into the body of the mosquito and it can give

Only one family of mosquitoes can carry

having the disease. But, as we cannot always
