Natural history from the point of view of animal psychology, which explains habits, behavior and reactions as observed in laboratory and field investigation. Pretty fascinating stuff -- the doings of animals in relation to their instincts and senses, learning adaptations and memory; emotions, sex, play, parenthood, competitions, cooperation and response to stimuli. Studies, along the lines of the famous ones of Pavlov, have produced results the methods and means of proof of which are clearly outlined. There are parallels of beast to man, distinctions of abnormal vs normal findings, results of conflicts, all applying to possibilities of the realities of animal existence. Exploration in new fields, with indications of potentialities of the discoveries and widening knowledge. Scientific-minded young people interested in animals should find this right down their alley.
