Abstract
THIS volume is a somewhat extended form of the Joseph Leidy Memorial Lecture in science delivered in March 1936. Prof. Parker's recent work has led him to the conclusion that the chromatophores in fishes are controlled by neurohumors which are liberated by nerves. They may be divided into two classes the hydrohumors, such as the substance liberated by the pituitary gland, which are carried in the circulation, and the lipohumors, which are oil-soluble substances liberated by nerve endings in the skin and diffusing slowly from one area of skin to another. The book describes the experiments on which these conclusions are based. It is well illustrated and attractively produced.
