Originally published in 1956, 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. Designed to be used with living specimens at hand, the text is based around the study of plants and animals found in familiar and accessible habitats. This book will be of value to anyone with an interest in the teaching of biology and the history of education.
