leucocyte

As soon as a leucocyte touches a resisting body it reacts to the contact by applying the largest possible surface to it.

Hence the danger to the individual leucocyte is minimized and the maximum effect obtained.

Surely now the regular leucocyte cavalry have them at their mercy, and can cut them down at leisure.

The result is the pigmented leucocyte, so characteristic of malarial blood.

It stood out sharply when he focused—the white, jellyfish shape of a single-celled leucocyte.
