First published in 1922, as the second edition of a 1903 original, this book was written by the British naturalist and clergyman Leonard Jenyns (1800-93), later known as Leonard Blomefield. The text was edited by Sir Francis Darwin (1848-1925), the son of Charles Darwin, and published posthumously. It contains a calendar of observations on plants and animals kept by Jenyns in Swaffham Bulbeck, Cambridgeshire. This book will be of value to anyone with an interest in the writings of Jenyns, botany, zoology and the history of science.
