Abstract
THIS volume has been prepared for use in higher schools during a year's course of five hours per week. The frog and the bean-plant are taken as types for the study of animal- and plant-structure and biology. The succeeding part of the book contains an account of the structure and life-histories of “seed-plants” and “spore plants” (ferns, mosses, algae, fungi, and bacteria). The chief phyla of the animal kingdom are traversed in the third part of the book; but the authors have attempted to compress too much material into these 140 pages, with the result that many subjects are necessarily considered so briefly that only imperfect ideas of them are Conveyed. For instance, “Paramecia reach a state when they are unable to continue to divide. Two such individuals come into contact, and through their delicate cell-walls some of the nucleus of each one passes over to join the nucleus of the other,”—is surely an incorrect and inadequate account of the conjugation phenomena. There are a few slips in this part of the work, e.g., the sword-fish is placed among the cartilaginous fishes. The succeeding part of the work deals in an interesting manner with the structure of the human alimentary canal, digestion, food-values, blood, respiration, excretion, and nervous activity, and leads up to an application of biological principles to personal hygiene.
