The Committee take this opportunity of recording their 
sincere thanks to those Noblemen and Gentlemen, who, by 
opening their Houses and Grounds to the Society, have contributed 
so largely to the enjoyment of the Field Excursions. 
Six General Meetings were held during the winter of 
1872-78, in which Lectures on general subjects connected with 
Natural Science were delivered. They are as follows :— 
1, October 28, 1872.— Animals: their Structure, Habits, and Instincts,” 
by E. A. Davinson, Esa. 
November 27, 1872.—% Deep Sea Dredging,” by the Rev. Canon 
Kiunestry, President.

. 
3, Jan. 30, 1873.— Cave-hunting in Yorkshire’ by W. Boyp Dawkrss, 
Esa, F.R.S. 
4, February 27, 1873.—‘* The Vegetable Cell,’”’ by the Rev. J. L. Beprorp, 
M.A.,F.L.S. 
. March 27, 1873.—* On the Growth of Corals,’’ by the Rev. H. H. 
Hicerns, F.G.S., President of the Liverpool Naturalists’ Field Club. 
Or 
6. April 24, 1873.—* Musical Vibrations,’’—with experiments—by Mr. J. 
H, Harrison. 
This last most interesting Lecture by Mr. Harrison dis- 
covered to our Society the want of some addition to its objects 
of study, which had been previously limited to Botany, Geology, 
and Zoology, and therefore the Committee hope that during 
the ensuing winter a fourth Section may be added, to embrace 
some of the so-called Physical Sciences, such as Astronomy, 
Chemistry, Light and Heat, and Electricity, &c., &c. 
The Botanical Section, last year, was indebted to the 
Chairman (the Rev. J. Harris, M.A.); to Mr. Cross; and to 
Mr. G. W. Survssoxz, F.G.S., for Papers on Botany. During 
the winter, the Rey. J. Harris read a series of Papers on 
the Natural Orders, commencing with the N. O. Composite, and 
ending with N. O. Conifere. 
In the Zoological Section, Papers were read by the Chair- 
man, Mr. A. O. Waker; Dr. SrotrerrotH; Dr. Dosie; 
Mr. J. C. Stivens; and Mr. A. River.
