Originally published in 1958, this book was written to provide biology students with a guide to the study of nature during the first three years of grammar school, so that they could develop a sound understanding of the area prior to the beginning of their preparation for the G.C.E. examinations. The text is based around the study of plant and animal families, and information is also presented on the characteristics of plant and animal life and human physiology. This book will be of value to anyone with an interest in the teaching of biology and the history of education.
