"This book is intended primarily for students of Botany. Such a student's knowledge of plant products is usually obtained [...] from Organic Chemistry, [...] from Plant Physiology; between these two standpoints there is a gap, which, it is hoped, the following pages may help to fill." Green boards are soiled, rubbing to edges and corners, gilt details on spine. Some soiling on page edges. Many annotations throughout the text as well as heavy note-taking on the front and back blank endpages.
