Parallel Paths; A Study in Biology, Ethics, and Art

IN a recent work by an eminent man of science, Dr. J. Reinke, Professor of Botany at the University of Kiel, there occurs a passage which I cannot do better than place in the forefront of this book as an indication of its aim.

“Physiology,” writes Professor Reinke, “has become the study of the movements which, taken together, make up life. There is no manner of doubt that nourishment, metabolism,1 reproduction, development, and sensation rest on processes of movement which depend on material systems of peculiar molecular conformation. For the bodies of plants and of animals are material systems whose conformation is of a most intricate character.
