to pieces to feed their little ones, but this is only after their teeth begin to grow, and like the babies of the human family they are old enough to feed at the same table and eat the same kind of food as older members of the family. Many do not realize what a great number of our animal friends belong to this great family of Mammals or Mammalia, from the Moles and the Bats to the huge Mastodons of past ages. Even some of the large water animals are included in it, like the Seals, the Whales and their numerous relatives—the Dolphins, Porpoises, Narwhals, etc. The latter are usually called fishes by those who do not understand this division into orders and families; they are not fishes, however, but belong to the Water Mammalia. And in dividing this book into Animals, Birds and Fishes, all these members of the Whale family will be found where they belong with the great family of Mammalia. Then after classifying all Mammals both of land and water under the one great family, or order, the Latin terms help to sub-divide them into smaller families, more closely related, in such a manner that all the readers of different languages may understand the meaning of the words because of their Greek or Latin origin. Thus we know that a quadruped is a four footed animal because the term comes from the Latin words quatuor, four, and pes, pedis, a foot. And the term quadrumane comes from quatuor, four, and manus, a hand, which makes it easy to understand that all the animals classified under “Quadrumana” belong to the monkey family, who have four hands instead of four feet, with regular thumbs and fingers on the hind hands (which are usually known as feet) as well as on the front ones. Thus the word Quadrumana distinguishes this whole four-handed family from the Bimanes, or two-handed family, to which mankind belongs (making an order by itself) and the Quadrupeds, or the great four-footed family. In the same manner the family to which the Horses belong are not only quadrupeds, but they have very thick skin. They are, therefore, classified under the term Pachydermata, made up of two Greek words meaning thick and skin. We often find many of the Mammalia arranged in orders, or large groups, before being divided and sub-divided into families and smaller groups. Thus the Dog family and the Cat family are both included under the order of Carnivora, or carnivorous quadrupeds, which is derived from the two Latin words caro, carnis, flesh, and vorare, to devour; and we know that the animals found under this order prefer a diet of flesh food, and devour other animals in their wild state.
