Reviews of : Biology and Human Welfare by James Edward Peabody PDF Book
Inside this Book – In the teaching of high-school biology in former days the principal emphasis was laid on details of external and internal structure and on classification of plants and animals. Somewhat later a study of the functions of living organisms became the core of biological teaching. While of course all of these aspects must receive due consideration in a biological course, the authors believe that high-school boys and girls find greater interest and benefit in considering the applications of this subject to human welfare. Scientists are learning more and more ways to counteract the effects of harmful plants and animals and to develop those organ- isms that minister to everyday living. Flowering and flowerless plants, mammals, birds, fishes, insects, and protozoans furnish a wealth of material for studies that naturally appeal to adolescents. Problems relating to these groups of living things occupy a central place in this text. Other problems are suggested in the questions and applications at the end of each of the units.
Inside this book –Biology and Human Welfare PDF Book by James Edward Peabody – It is impossible for the authors to express in any adequate way their appreciation for the generous help given us by the experts in their various fields in Boston, Cambridge, Albany, New York City, Washington, Chicago, and Denver. In the preparation of the sections relating to alcohol, for instance, we have had personal conferences with over 50 of the widely recognized authorities in medicine, biology, education, life insurance, government, and social service. Their helpful counsel has enabled us to prepare a treatment of this subject which we believe will appeal to the intelligence of adolescents. We are also deeply indebted to the experts in the Federal Departments in Washington for a careful checking up of our statements on birds and mammals (Dr. W. B. Bell and his assistants in the Biological Survey), insects (Dr. L. 0. Howard, Dr. F. C. Bishopp, and other members of the staff of the United States Bureau of Entomology), plants (Dr. F. V. Coville and other experts in the Bureau of Plant Industry), fishes (three members of the Bureau of Fisheries), forests (Dr. W. N. Sparhawk). These men have also supplied us with valuable illustrations.
