Appendix. vii Scientific Meetings and Memoirs Contributed.— Bight Ordinary Scientific Meetings have been held in addition to Ordinary Meetings held for the election of members at Field Meetings. The number and character of the papers and addresses at these meetings fully sustain the character of previous years. In order to prevent in some measure the too rapid accumulation of papers which must be printed in the ' Transactions,' the Council has authorised the Secretary, on two occasions, to obtain the services of well-known naturalists as lecturers, and this plan has worked so well that it is intended to repeat it as occasion may require. The following is a list of memoirs and addresses delivered to the Club during 1885, excluding short notes on exhibits and verbal communica- tions :— "The Life and Work of John Ray, and their relation to the Progress of Science."
