THERE is at present a small collection of books, etc., known as the Darwin Library, at Down House, Downe, Kent, the home of Darwin from 1842 until 1882, which is now in the hands of the British Association. The major part of the existing collection consists of Darwin's own library, which belongs to the professor of botany in Cambridge for the time being, and was generously replaced in Down House by Sir Albert SeWard during his tenure of that chair, an action confirmed by his successor, Prof. F. T. Brooks. For the rest, the number of Darwinian books in the possession of the Association is not large ; whereas inquiries concerning such books are not infrequently made by visitors and others. The Down House Committee of the Association is endeavouring to collect (a) all biographies of Darwin ; (b) contemporary works on Darwinian theories and kindred subjects ; further (c) the collection of Darwin's own publications (books and papers) is not complete ; and (d) the Committee would gladly receive and preserve contemporary reviews of Darwin's works. Those who may be in a position to offer appropriate books or papers are asked, in the first instance, to communicate particulars thereof to the Secretary, British Association, Down House, Downe, Kent, in order that duplication may be avoided.
