FIGS. 119-124. From dried blood-films showing parasites of malarial 

 fever. Magnified about 1000 diameters. 



Fig. 119. Early intra-corpuscular form of the "mild tertian" parasite. Fig. 120. 

 Large intra-corpuscular form of the same parasite, showing scattered pigment 

 granules ; the invaded red corpuscle is much enlarged. Fig. 121. Two members of 

 the " rosette " series of the same parasite ; that to the right shows the radiate 

 segmentation, that to the left is an earlier stage. In both the pigment is collected 

 in the centre. Fig. 122. Two "ring-forms" of the quotidian parasite, within red 

 corpuscles. Fig. 123 shows a "crescentic body"; from a case of malignant tertian 

 fever. Fig. 124. A flagellated organism, derived outside the body from a crescentic 

 form. (All these figures are from negatives or preparations kindly lent by Dr.
