He finds that in form, in the presence of starch, of chlorophyl, in power of locomotion, in the presence of circulatory organs, of the body called nitrogen, in the functions of respiration and sensation, there are no diagnostic characters. He finds, however, "fairly constant and well-marked distinctions" in the presence of a cellulose coat in the plant-cell, in digestion followed by absorption, and in the power to manufacture protein. The _morphological_ feature of plants is this cellulose coat; of animals, its absence; the _physiological_ peculiarity of plants, this _manufacturing power_; of animals, the want of it. But after all the discussion he says: "To the question, _Is this an animal or a plant?_ we must often reply, _We do not know_."--_The Microscope._ * * * * * CAMELLIAS.
