H^MATozoA IN Man (Malaria). 



In 1880 Laveran, in Algiers, noticed the existence of peculiar 

 structures in the blood of a patient suffering from malaria, and 

 his researches were communicated to the Academy of Medicine in 

 Paris in 1881 and 1882, and subsequently pubKshed in exienso in a 

 treatise on the subject. 



Laveran described various bodies which he was led to regard as 

 different stages in the life-history of the same micro-parasite. The 

 most striving forms were cylindrical elements with pointed extre- 

 mities. They were crescent-shaped and pigmented in the middle. 

 There were other forms, more frequently foiind, which were either 

 free in the serum or in contact with the red blood-corpuscles. 

 They were more or less spherical, pigmented, and endowed with 

 amoeboid movement. Other forms, again, were provided with motile 

 filaments three or four times as long as the diameter of a red blood- 

 corpuscle. And, lastly, there were little masses of hyaline material, 

 which Laveran regarded as dead forms. 



These observations at first attracted Httle attention ; but they 

 have since been confirmed and extended by Richard, Councilman and 

 Abbot, Marchiafava and Oelli, Golgi, Sternberg, Osier, the author, 

 Va;ndyke Carter, Manson, and others, and their importance fuUy 

 recognised. 



The different forms assumed by the hsematozoon of malaria may 

 be described in two groups : those within the red blood-corpuscles, 

 and those free in the serum. 



Intra-corpuscular bodies. — These are of three kinds. First,
