On The Negative And Positive Phototropism Of The Earthworm Allolobophora Foetida, Sav., As Determined By Light Of Different Intensities (1903) is a scientific study conducted by George P. Adams. The book explores the behavior of earthworms in response to different intensities of light. Specifically, it focuses on the phototropism of the Allolobophora foetida species of earthworms, which refers to their tendency to move towards or away from light sources. Adams conducted experiments to determine how these worms responded to varying levels of light intensity, and his findings are presented in this book. The research sheds light on the behavior of earthworms and provides insight into how they interact with their environment. This book is a valuable resource for anyone interested in the study of animal behavior or the biology of earthworms.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
