A vote was passed, that the President appoint at leisure a committee of three to con- 

 sider the desirability of aholishing the Committees in the departments, and of devising a 

 different jjlan for organizing the Council, and to propose the necessaiy change in the Con-

The Semi-Centennial Celebration of the Foundation of the Society ; April 28. 



The anniversary day was pleasant and all things conspired to render the occasion inter- 

 esting and joyous. The spacious platform which had been erected across the north portion 

 of the main hall was occupied by the President, the speakers, the officers of the Society 

 and a large number of ladies and gentlemen. A large audience, composed of members of 

 the Society and very many prominent men and women of the city and State, filled the floor 

 of the hall and such portions of the galleries as were convenient to use. Amongst the dis- 

 tinguished persons present, were His Excellency Governor Long, President Eliot of Har- 

 vard University, Prof. Asa Gray, the illustrious botanist, Alexander Agassiz, Director of the 

 Museum of Comparative Zoology, Count Louis Francois de Pourtales, Dr. Samuel Eliot, 

 Superintendent of the Public Schools, Miss Lucretia Crocker, Supervisor of the Public 

 Schools, Dr. D. Humphreys Storer, Judge G. W. Warren, Prof F. W. Putnam, Rev. Robert 

 C. Waterston and Mrs. Waterston, Hon. Josiah Quincy, Prof E. S. Morse, Colonel Theo- 

 dore Lyman, Dr. J. C. White, Mr. Justin Winsor, Librarian at Harvard LTniversity, and Mr. 

 John Cummings.

 once to present what I have prepared for the occasion. It is an account of the doings of 

 those who took an active part, before the Society was formed, in interesting the pulilic in 

 natural history. I do this because their labors have not been duly appreciated, and because 

 the lessons which their experience is designed to teach certainly require that we should 

 take tune to do it. What I hold in my hand is intended as an introductory chapiter in the 

 history of the Society of Natural History on which 1 am engaged, — a memorial volume 

 to be issued this year. 



The President then proceeded to present the early steps taken to inculcate a love for the 

 study of nature in this community, particularly dwelling upon the formation of the Lin-
