How was it that no one asked himself how it was possible that the plasmodia could enter the current of the blood from the air?
Plasmodia vary in color in different species and at different times in the same species.
The most satisfactory studies are obtained by plasmodia carefully brought in directly from the field.
Do not their amœboid spores and plasmodia ally them at once to the amœba and his congeners, to all the monad, rhizopodal world?
Malaria and similar diseases are caused by plasmodia, which are protozoa and not bacteria.
