Richard Prairie, Charles Franks and the Online Distributed Proofreading Team [Illustration] PATHFINDER PHYSIOLOGY No. 3 HYGIENIC PHYSIOLOGY WITH SPECIAL REFERENCE TO THE USE OF ALCOHOLIC DRINKS AND NARCOTICS BEING A REVISED EDITION OF THE FOURTEEN WEEKS IN HUMAN PHYSIOLOGY BY JOEL DORMAN STEELE, PH.D. ENLARGED EDITION WITH SELECTED READINGS _Edited for the use of Schools, in accordance with the recent Legislation upon Temperance Instruction_ INDORSEMENT. BOSTON, _June_ 20, 1889. The Pathfinder Series of Text-books on Anatomy, Physiology, and Hygiene consists of the following volumes: I. Child's Health Primer (for Primary Grades). II. Hygiene for Young People or, Young People's Physiology. (for Intermediate Classes) III. Hygienic Physiology (for Advanced Pupils). The above are the series originally prepared (as their general title indicates) to supply the demand created by the laws for temperance instruction in public schools in the United States. They were written by experts under the supervision of the Scientific Department of the National Woman's Christian Temperance Union, published by the instigation of the same, and have been carefully revised from time to time, under the same supervision, to keep them abreast with the latest teachings of science. Being both teachable and well adapted to grade, their educational value, as proven by schoolroom tests, is of the highest order. We therefore cordially indorse and highly recommend the Pathfinder Series for use in schools. MARY H. HUNT, _National and International Superintendent of the Scientific Dep't of the Woman's Christian Temperance Union; Life Director of the National Educational Association._ ADVISORY BOARD: JOSEPH COOK, WILLIAM E. SHELDON, ALBERT H. PLUMB, D.D., DANIEL DORCHESTER, D.D. PREFACE The term Physiology, or the science of the functions of the body, has come to include Anatomy, or the science of its structure, and Hygiene, or the laws of health; the one being essential to the proper understanding of physiology, and the other being its practical application to life. The three are intimately blended, and in treating of the different subjects the author has drawn no line of distinction where nature has made none. This work is not prepared for the use of medical students, but for the instruction of youth in the principles which underlie the preservation of health and the formation of correct physical habits. All else is made subservient to this practical knowledge. A simple scientific dress is used which, while conducing to clearness, also gratifies that general desire of children to know something of the nomenclature of any study they pursue. To the description of each organ is appended an account of its most common diseases, accidents, etc., and, when practicable, their mode of treatment. A pupil may thus learn, for example, the cause and cure of "a cold," the management of a wound, or the nature of an inflammation.
