FIG. 13. A group of red blood-discs agitated and distorted by a slender lashing
filament, which had become detached from a neighbouring flagellated
body, during its brief movements under scrutiny: the thrilling aspect
amongst the corpuscles was very evanescent, and being detected in two
or three separate parts of the field, it seemed, that more than one
flagellum was liberated or else after detachment one had continued to
travel. An appearance not very rare.

FIG. 14. A phagocyte containing in its interior two pigmented spheroids.

FIG. 15. Melanæmia. A group of pigmented structures seen together in the
blood, the day after ‘crisis’ of paroxysmal fever—CASE No. 6. At a
an enormous nucleated cell (? splenic endothelium) loaded with pig-
ment masses (‘melanine’, so-called), extra-nuclear in site and opaque-
black in tint: many such cells were present. At b an ordinary
smaller leucocyte; also common. At c spheroidal, cylindrical, and
semi-lunar organisms (some red corpuscles also added), which were seen
in proximity and likewise not infrequent.
