In this second book, the author presents animal physiology. The teacher and parent will observe, that in doing this the author brings out quite prominently the analogies that exist between the animal and the vegetable world in the operations of life. Such analogies are always interesting to the child as well as to the adult, and the consideration of them adds much to the enjoyment of the observer of nature, for it opens to them the simple plans and principles upon which the Creator works out the almost endlessly varied results that life, both animal and vegetable, presents to view.
