Forced Movements, Tropisms, and Animal Conduct

Abstract

A PROLIFIC investigator does a great service to his brethren when, without waiting to write an elaborate treatise, he collects the gist of some considerable portion of his work into a book; and if the book be a small one, so much the better. This Prof. Loeb has now done, and we are immensely obliged to him. What is more, his volume is but the first of a series, by American writers, all dealing with the wide field of experimental biology, a field in which we at home have done comparatively little, but in which American biologists have greatly distinguished themselves. Among the promised monographs are one by Prof. Morgan on "Chromosomes and Heredity"; another, by Dr. Jennings, on "Pure Line Inheritance"; a third, by Dr. T. B. Robertson, on "The Chemical Basis of Growth"; and a fourth, by Prof. Osterhout, on "Permeability and Conductivity of Living Tissues."In every case (and there are many more besides these) the author has won, and more than won, his right to be heard, and in every case also we feel the need of an authoritative guide to the subject in question.
