DESCRIPTION OF PLATE IV 

 Malarial Parasite 



43. To the left a young (spore) tropical parasite. To the right a medium 

 and large tropical parasite. 



44. An almost fully developed tropical parasite. The black granules are 

 pigment heaps. 



45. Young parasites separated from one another. Broken up division 

 forms twenty-one new parasites. 



46. To the left a red corpuscle with basophilic, karyochromatophilic 

 granules. Prototype of malarial parasite. On the right a red blood corpuscle 

 with remains of nucleus. 



Sexual Forms or Gametes 



47. An earlier quartan gamete (macrogametocyte in sphere form), female. 



48. An earlier quartan gamete (microgametocyte), male. 



49. Tertian gamete, male form (microgametocyte). 



50. Tertian gamete, female (macrogamete). 



51. Tertian gamete (macrogametocyte still within a red blood corpuscle. 



52. Microgamete tertian within a red blood corpuscle. 



53. Tropical fever. (^Estivo-autumnal) gamete, half moon (crescent) still 

 lying in a red blood corpuscle. In the middle is the pigment. The concave 

 side of the crescent is spanned by the border of the red blood corpuscle. 



54. Gamete, tropical fever parasite. 



55. Gamete of tropical fever parasite heavily pigmented. 



56. Gamete of the tropical fever parasite (flagellated form), microgameto- 

 cyte sending out microgametes (flagella or spermatozoon).
