The President's Address. 99 such subjects appears to be the belief that some special quality of mind is necessary, and many who are really interested in the pursuits of the naturalist allow their interest to remain passive for this reason. But the neces- sary qualities of mind really differ in no way in kind from those possessed by any person of average intelligence. Professor Huxley is never tired of insisting that science is but organized common sense :—"Anyone who looks into the matter attentively will soon perceive that there is no solid foundation for the belief that the realm of science is thus shut off from that of common sense, or that the mode of investigation which yields such wonderful results to the scientific investigator is different in kind from that which is employed for the commonest purposes of every day exist- ence. Common sense is science exactly in so far as it fulfils the ideal of common sense—that is, sees facts as they are, or, at any rate, without the distortion of prejudice, and reasons from them in accordance with the dictates of sound judgment. And science is simply common sense at its best; that is, rigidly accurate in observation, and merciless to fallacy in logic."* These statements, coming from one of the masters of biological science, must surely hold out every encouragement to those who desire to take up the study of these subjects. There is no one amongst us but, after he has once acquired a substantial ground- work in some branch of our studies, can do real service to the Club and to science at large, and I only hope that our next volume of publications will show that these remarks have fallen upon fertile soil. In many scientific societies it is customary for the President to occupy the attention of the members at the annual meeting with a discourse upon some special branch of science with which he is most familiar, and although this is a custom of which I greatly approve, I much regret that my numerous occupations have left me without the time necessary for collecting the materials for such an address. * "The Crayfish: An Introduction to the Study of Zoology," 1880, pp. 1 and 2.
