TABULAR STATEMENT OF THE CHARACTER
(Modified from
| Duration of development | Movement | Hæmozoin | Maximum size | Form of segmentation | |
| 1. Quartan parasite, Plasmodium malariæ | Seventy-two hours | Slight movement in the immature forms | Coarse grains; little or no movement | The size of a red blood-corpuscle | Daisy form; the single spores roughish, with distinct nucleolus |
| 2. Tertian parasite, Plasmodium vivax | Forty-eight hours; or less in anticipating types | Active amœboid movement in the immature and also in the middle-aged forms | Finer granules in immature forms; often in the larger actively swarming | Size of a red blood-corpuscle; sometimes even larger | Sunflower or grape-like; single spores small, round; nucleolus rarely seen |
| 3. Pigmented quotidian parasite, Laverania præcox | Twenty-four hours | In the unpigmented immature stage very actively amœboid; less active when hæmozoin accumulates | Very fine; later coalesces in one or two clumps; does not swarm | 14-13 the size of a red blood-corpuscle | Irregularly formed heap |
| 4. Unpigmented quotidian parasite, Laverania immaculata | Twenty-four hours or less | Very active amœboid movement | None | 15-14 the size of a red blood-corpuscle | Star-shaped, or in irregular heaps |
| 5. Subtertian parasite. Laveraniamalariæ (Plasmodium falciparum) | Forty-eight hours or less | Active; the movement remains present in the pigmented stage | Fine; often shows oscillatory movement | 12-23 the size of a red blood-corpuscle |
Irregular heaps |
