102 THE COMING OF AGE OF stimulation of original local work in various branches of natural science Such lectures and addresses, although in many cases delivered by acknowledged masters of the various subjects, could not very well be published in extenso by the Club, and so the records of this branch of our work do not figure very prominently in our printed pages. Nevertheless this work is in its way both useful and important, provided it is kept in abeyance as a secondary branch and not allowed, as is the case with many local societies, to become the main object of the Club's existence. A long course of experience in connection with the working of local societies throughout the United Kingdom, derived from my association with the Corresponding Societies' Committee of the British Association, has served to convince me that the work of a local society is weak in proportion as it has to depend upon popular lectures for keeping it alive. Quite early in the history of the Club educational work of this kind was undertaken and the system of popular lecturing inaugurated by a lecture by Mr. Harting on Nov. 10th, 1880, on Forest Animals (Trans. I., 74). The second lecture in this series on January 4th, 1881, was a memorable one, as Mr. Alfred Russel Wallace, our distinguished Hon. Member, gave an abstract of the main conclusions at which he had arrived con- cerning insular faunas and floras (Proc. I., lxvi.), the subject of the great work, afterwards published under the title Island Life. Again, on October 2nd, 1886 (Proc. IV., cxcii.) my friend, Mr. Wallace, favoured the Club with an advanced chapter of his work on Darwinism, then in course of prepara- tion. But time will not admit of a detailed list of lectures, addresses and demonstrations given before the Club at head- quarters or elsewhere. I need only justify this branch of our work by reminding you that we have had the privilege of hearing in this capacity Sir Richard Owen, Gen. Pitt-Rivers, Sir Wm. Flower, Dr. Henry Woodward, Mr. F. W. Rudler, Prof. E. B. Poulton (whose recent appearance on February 22nd, 1902, was his third lecture to the Club), Mr. Arthur Lister, Dr. M. C. Cooke, Mr. G. Massee, Mr. D.J. Cunningham ("Transformations of Marine Animals," Essex Naturalist VII., 182), Prof. Charles Stewart, Mr. Frederick Enock and others. Perhaps also the address on "The Mechanical Questions involved in the Flight of Birds," delivered by Lord Rayleigh on the occasion of the Club's visit to Terling Place in 1885 (Proc. IV., clxxiii.) may be
