Zoology Descriptive PDF Download

Excerpt from Zoology: Descriptive and Practical, Descriptive They should be studied before the season Of frosts. On the other hand, fishes can as well, or better, be studied later. Since the natural history point of view is prominent, the general principle regulating the order of study should be, follow the season. The birds, too, should receive attention during the first part of the term, for many of them migrate early. It is not necessary, nor always desirable, to complete the study of one group before beginning another. Two lines of work can profitably be pursued on alternate days or weeks. For fall work, the order here given has been found satisfactory. But circumstances call for considerable variation; it is not necessary ta follow any given order with slavish fidelity. If the work begins in th spring, the teacher may prefer to begin with the crayfish, clam, fish, or frog. There are some advantages in beginning with the lowest animals and studying them in the ascending order. This gives the clearest idea Of the natural sequence Of the animal kingdom.
