Excerpt from Life and Health: A Text-Book on Physiology for High Schools, Academies and Normal SchoolsEvery thoughtful young person must have asked himself a hundred questions about the problems of human life: how it can be that the few articles Of our daily food - milk, bread, meats, and Similar things - build up our complex bodies, and by what strange magic they are transformed into hair, skin, teeth, bones, muscles, and blood.How is it that we can lift these curtains Of our eyes and behold all the wonders of the world around us, then drop the lids, and though at noonday, are instantly in total darkness? How does the minute structure Of the ear report to us with equal accuracy the thunder Of the tempest, and the hum of the passing bee? Why is breathing so essential to our life, and why cannot we stop breathing when we try? Where within us, and how, burns the mysterious fire whose subtle heat warms us from the first breath of infancy till the last hour of life?These and scores of similar questions it is the province of this deeply interesting study of physiology to answer.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
