YATES, Esq., PRESIDENT, in the Chair. ON taking the chair, the President stated, that a wish had for some time existed amongst the members of the Society, and those of the Natural History Society, to form a union of the two Societies; in consequence of which, meetings had taken place between delegations from both, at which the terms of union had been arranged. These would be submitted to the consideration of the members, and, if they met with their approval, the two Societies would be at once amalgamated. The terms were, generally, that the Members of the Natural History Society should be at once received as Members of the Literary and Philosophical Society, without any fresh ballot, or the payment of any entrance fee; that the funds of the two Societies should be united; that a third of the Society's Meetings should be devoted to the consideration and discussion of questions of Natural History; and that a liberal proportion of the Members of the Council should be selected from amongst the Members of the Natural History Society. On the motion of Dr. Hume, which was duly seconded, the union was agreed to unanimously; and Dr. Hume, Dr. Brett, and Mr. Cunningham, were deputed to inform the Members of the Natural History Society of the result, and to invite their attendance to take part in the election of officers, and in the general business of the Society. In a few minutes the Members of the Natural History Society entered the Room, and were received with the warmest expressions of pleasure. B The following gentlemen were then elected Officers for the year:— President JOSEPH BROOKS YATES, Esq. Vice-Presidents-Rev. Dr. TATTERSHALL, Dr. DICKINSON, and Mr. ARCHER. Treasurer-Dr. DUNCAN. Secretary-Mr. YANIEWICZ. Council-Dr. BRETT, Rev. Dr. HUME, Mr. CUNNINGHAM, Dr. WATSON, Mr. SWEETLOVE, Dr. DICKINSON, Mr. ARCHER, and the Rev. J. C. PRINCE, together with the PRESIDENT, the Senior VICE-PRESIDENT, the TREASURER, and the SECRETARY, who are members ex officio. Mr. E. Kemp, Mr. G. Simpson, and Mr. Thomas Inman were admitted Members of the Society. The ordinary business of the Society having been disposed of, The PRESIDENT delivered the following ADDRESS : "OUR Society having been augmented by the recent union with the "Natural History Society" of Liverpool, I sincerely congratulate the collective body upon the auspicious event, which will, doubtless, be attended with most advantageous results. The Natural History Society has numbered in its ranks several distinguished members, with whose researches we shall henceforward be more intimately acquainted. And it is no light privilege to have among us those who pry into the arcana of animal and vegetable economy-adapting them to the use and enjoyment of man, and leading us, by a delightful induction, to an increased knowledge of the Great Author of all happiness, and order, and moral fitness. Permit me now to express an ardent hope that, with our concentrated forces, we are (at the opening of the present session) entering upon a field of brilliant achievements in Science, Literature, and the Arts. "But whilst we anticipate these results from our internal resources, surely the aspect of external circumstances |
