HE Natural History of Animals has always been a most interesting and instructive subject, and its popularity increases yeai- after year. It is a branch of knowledge which is entertaining at every age, and it is a favourite stuUy with men of eveiy race and country, and of every intel- lectual capacity. AJl children delight in having their little tasks assa ciated with pictures of animals, and the alphabet is learned all the more readily by its being illustrated \vith spirited drawings of household pets and the terrible creatures of the woods. The marvels of the intelligence of the dog and hoi-se are inexhaustible soui'ces of delight to joung readers ; and there are few greater pleasures than those which are felt when living animals, whose descriptions and habits have been the subject of instruction and amusement, are seen in some large menagerie or zoological gardens. On the whole, it is probable that few books are so interesting to young men and women as those wlucli relate to animals, and it is their study which, in the majority of instances, leads to the desire for further knowledge of Natural History. The young student soon begins to yearn for iiifonnation regarding the manner in which diiferent creatures live; how some breathe air, how othere live in water; how it is that some fly and othere crawl; and he desires to comiect the peculiar construction of animals with theii- method of life. Or he may l>e content with endeavoiu-ing to understand the names of animals, and the reasons why they are arranged or classified in a particular manner by scientific men. As yeai-s roll on, if the interest in Natural History has not diminished, the man, with increasing intelligence and scope of reading, masters the knowledge desired in his youth, and has the opportunity, should he cai-e to gi-asp it, of the highest intellectual enjoyment. He can enter into the consideration and discussion of the mysterious problems of life : of its origin; of the reasons why animals difler; why they are distributed here and there, or limited in theii- position in the world ; what connection there may be between those of the past and of the present, and of the relation between ' the creation and the Creator. Be-sides tliis, even should he not aim so high, the man who has had a slight training in Natural History often employs his knowledge for the benefit of art and commerce. How beautiful are the representations of animals on some old coijis, how gi-otesque are those on others ! Yet the most correct, and, therefore, the most beautiful, were the result of the careful study of Nature, ^\^lat benefits to men have resulted from the production of certain breeds of horses, sheep, and oxen ! But it has been the study of Nature, and of the laws of the powei-s of inheritance, which led to most of these results: and thus the practical man is dependent upon the student for his success. NotwithstancUng the interesting nature of the study of the Natural History of Animals, there is xiv AATCHAL HISTOKV. certainly iiiorj interest taken in it during early life than later on. As a rule, men have no time for it, or they iind that, after gaining a certain amount of knowledge, they must study hard if further progress is to be made. Moreover, the vast amount of useless things which had to be learned at school and college ha\e no relation to Natural Historj-, except, perhaps, to convey erroneous ideas and to teach flibles, so that tliis important science lias generally to be begun in earnest after the usual education has been completed. When the determination has been made to learn the Natural History of Animals, the student will have to study two separate, yet iiiter-dependent, branches of knowledge, namely. Zoology and Comparative Anatomy : for the one considers the external shape, habits, distribution, and classification of animals, and the other refers to their internal construction, anatomy, and physiology, and the relation which the internal parts bear to the external in the scheme of classification. These stu
