HJGMATOZOA 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 published in extenso 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. ] 

 most striking forms were cylindrical elements with pointed azl 

 ruities. They were crescent-shaped and pigmental in tin* middle. 

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

 free in the serum or in contact with the red blood-c< 

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

 amceboid movement. Other forms, again, were provide! with motile 

 filaments three or four times as long as the diameter of a r.-d hlood- 

 corpuscle. And, lastly, there were little masse- of hyaline material, 

 which Laveran regarded as dead forms. 



These observations at first attracted little ai hut t hex- 



have since been confirmed and extended by Richard. < 'minrilman and 

 Abbot, Marchiafava and Celli, Golgi, Sternberg, < Me- khor,

 recognised. 



The different forms assumed by the hematoznnn of malaria 

 be described in two groups: those xvi thin the red hi, ^-corpuscles, 

 and those free in the serum. 



Intra-corpuscular bodies. These are of three
