Introduction.—In this chapter only the more general methods and apparatus used in the study of behavior can be considered. The books of Jennings, of Mast, and of Loeb give adequate descriptions of the technical methods and the apparatus employed in the study of invertebrates. The presentation of the technique used in investigations of the behavior of vertebrates must necessarily be meager and incomplete. This field has been developed rapidly and the motives for development have been very varied. These differences in standpoint have had their effect upon the types of apparatus which have been devi...« less
