animalcule

This is a one-celled animal known as the paramœcium or the slipper animalcule (because of its shape).

Indeed, too sadly so, and I dare apply but a flash of the microscope to the rageing dilemmas of this animalcule.

These movements are termed amoebiform, because they quite resemble the movements of a small animalcule which is named amoeba.

Shall physical or chemical forces explain why the animalcule digs into the hard clay?

At one end of the ascending scale of organic life we see an animalcule swimming in the direction in which it is attracted by food.
