Early in the college year we called attention to the importance of the work which the various clubs were doing here at Harvard in interesting the students, by public lectures, in their different lines of work.

During the year, since that time, there has been great activity on the part of the various religious societies, the debating societies, the Camera Club, and the Natural History Society, in precisely this direction. This afternoon the Natural History Society offers the latest of this valuable series of lectures. Professor Edward B. Poulton, M. A., F. R. S., of Oxford University, will speak on the "Use and Meaning of the Colors of Animals in the Struggle for Existence;" the lecture will be illustrated by stereopticon views. This lecture will be directly in the line of a series of lectures on the "Colors of Animals" which Professor Poulton has been giving before the Lowell Institute. It will deal more thoroughly than these lectures with one phase of the subject. Professor Poulton is one of the best known of living zoologists and his lecture this afternoon is sure to be most interesting and most valuable. The topic of the lecture will probably suggest an entirely new idea to men who have never taken zoology or botany courses. To the ordinary observer the colors of animals and of plants and flowers are mere accidents. Yet this matter of color plays a most important part in animal and plant life and it is directly concerned in the great plan of life in general. As a matter of educational importance, then, this lecture is worthy of very great consideration and members of the University will do well to take time to attend to it.
