Of all the sciences, Zoology is the most extensive. It is estimated that over two million species of living creatures exist in the world. Between the elephant and the whale, the giants of animal creation, and the mite that is just discernible with the human eye, there are myriads of creatures differing in size, form and habit.

WHY AND HOW ANIMALS
ARE CLASSIFIED

It is highly desirable, therefore, to have before us a bird’s-eye view of the Animal Kingdom even if it is only occasionally brought into actual use by the average reader. Classification, it should be understood, is only a process of comparison for the purpose of enabling us to determine the exact place of each animal in the plan of Nature. In other words it is simply a scientific method of naming the various animals from the relation of their resemblances.

We are chiefly indebted to the great Swedish scientist Linnæus for the scientific method of naming animals. For his purpose, Linnæus used the Latin as the universal language of science. For example, he named the dog in his classification Canis familiaris, using a generic word and a specific word—just as they are used in the name of George Washington. In scientific classification, however, these names have become abstract terms, and they represent certain grades or degrees of resemblance which are spoken of as species, genera, families, orders, classes, and so on.

SCIENTIFIC CLASSIFICATION
OF THE DOG

In this way we determine the exact place of each animal. The dog belongs to the kingdom Animalia, sub-kingdom Metazoa, class Mammalia, order Carnivora, family Canidæ, genus Canis, species Familiaris, variety Hound (possibly) and its individual name, perhaps, is “Rover.”

The important thing is that the reader should have a picture of the actual animal representing each class in his mind’s eye. He should master the distinctions between the great groups, or classes, before proceeding to a more minute classification.
