The systematic study of the Distribution of living beings is the most modern branch of Biological Science, and came into existence long after Morphology and Physiology had attained a considerable development.

As we have seen, the study of yeast has led investigators face to face with problems of immense interest in pure chemistry, and in animal and vegetable morphology.

Employed in this sense, zoology, like botany, is divisible into three great but subordinate sciences, morphology, physiology, and distribution, each of which may, to a very great extent, be studied independently of the other.

Zoological morphology is the doctrine of animal form or structure.

The final object of physiology is to deduce the facts of morphology, on the one hand, and those of distribution on the other, from the laws of the molecular forces of matter.

The objection suggested by these questions is a very valid and important one, and morphology was in an unsound state so long as it rested upon the mere perception of the analogies which obtain between fully formed parts.

If we were to examine every animal in a similar manner, we should establish a complete body of zoological morphology.

Morphology and distribution might be studied almost as well, if animals and plants were a peculiar kind of crystals, and possessed none of those functions which distinguish living beings so remarkably.

But the facts of morphology and distribution have to be accounted for, and the science, the aim of which it is to account for them, is Physiology.

Morphology has taught us that it is a series of segments composed of homologous parts, which undergo various modificationsbeneath and through which a common plan of formation is discernible.

The Evergreens are a very interesting study and an excellent exercise in morphology for the older scholars.

The study of the different forms in which an organ may appear is the study of morphology.

The desperate resort to the analogical method of Commenius is confessed by Dr. Steinmetz, who talks of social morphology, physiology, pathology, and so forth.
