THE analysis of the numerical interaction that goes on generation after generation between a predator and its prey can undoubtedly throw much light upon the dynamics of animal populations. One of us (G. F. G.) has already summarised his experimental investigations of the subject (3, 4). However, he felt that it would be desirable to confirm some of his conclusions by a more extensive experimental material, and that in other cases the collected data should be accounted for theoretically in greater detail. It is the object of the present paper to give the results of our further investigations carried out along these lines.
Gause et al. (Fri,) studied this question.
