Excerpt from Lessons in Hygienic Physiology
For convenience in examining this book it may be well to insert a few page references, as the book is, in some respects, radically different from the usual school physiology. The book aims to teach the science and art of preserving health; the teaching is based largely on observational studies of the body, experiments, and study of the charts and figures which it contains. Observational study is carried out by frequent single questions and by more lengthy exercises (pp. 35, 86, 107, etc.). The experiments illustrate some point in physiology (pp. 14, 21, 25, etc.); they are not merely copied from texts on physics and chemistry, as is usual in those physiologies which are not wanting altogether in experimental work. To aid in founding the study upon facts and not mere words, the author has devoted a great deal of time to the illustrations. Books of this size usually have sixty or seventy figures; this book contains about three times as many, or one hundred and ninety-eight in all, sixteen of which are colored. Care has been observed to make use of only the best sources, and many figures are drawings of specimens hardened by the new formalin method (Figs.21 62, 68, 133, etc.). The author has made use of color (Plates IX to Xiii), for it has long seemed strange to him that in the geographies Maine is purple, Vermont red, and New Hampshire blue (when they are really none of these, but are green, brown, and white by turns), yet expense must be spared in the physiologies, and no hint given of the natural tints of the bodily organs. When physiology comes into its rights, the same care will be used in teaching the human body as in teaching the political divisions of Africa and Australia. There is a saying among teachers that there is no impression without expression. For testing the accuracy of what has been learned, review questions are abundant.
