The colored illustrations of malaria Plasmodia, pre- 

 sented herewith, were reproduced from original draw- 

 ings made under the direction of Dr. C. W. F. Winckel at 

 the Institute of Tropical Hygiene, Amsterdam, Holland. 



In the treatment of malaria cinchona bark and quinine have a history 

 of over three hundred years. While modern opinions differ as to 

 the correct dosage, the short quinine treatment advo- 

 cated by the former League of Nations Malaria 

 Commission is still followed by many. 



Quinine Dosage as recommended by the Malaria 

 Commission of the former League of Nations: 



20 grains of quinine sulfate for 5-7 days in 

 vivax malaria. Take no more quinine until 

 there is a recurrence or relapse, when the 

 initial dosage is repeated. Slightly more 

 quinine is needed for falciparum malaria.
