paper of the Session was by Mr. Robert Lloyd Patterson ; 

 subject : " Migratory Birds." On each of these evenings, 

 except the last, the chair was occupied by the President, 

 Professor Cunningham ; on the last evening, Professor Everett 

 presided, in consequence of the President's absence from Belfast. 

 The attendance of members and visitors at the evening meetings 

 was fairly maintained. 



The Secretary, Dr. Workman, having resigned his office, in 

 consequence of leaving Belfast, Mr. W. H. Patterson was ap- 

 pointed to the vacant post. 



A list of Donations to the Museum, and of Reports and other 

 Publications for the Society's library, is to be printed with the 

 present Report. The Council would thank the various donors 

 for their valuable gifts. 



The Museum was opened on Easter Monday to the public, at 

 a charge of two pence for adults, and one penny for children, 

 and the attendance was, as usual, very large.

 roof and walls, but these, along with some defects that came to

 reports that the buildings are in good order, and that the 

 collections are also in good order, and in several respects in an 

 improved condition.

 wall cases on the south side. The series includes represen- 

 tatives of all the great families of testaceous Mollusca. The 

 total number of specimens mounted at present is very nearly 

 7000, made up as follows : — Gastropods, genera 131, species 1320, 

 specimens 5467. Bivalves, genera 75, species 584, specimens 

 1362. These have been completely classified, mounted in their 

 proper order, and, with the assistance of Messrs. Workman and 

 Swanston, labelled with dates and localities, as far as could be 

 ascertained. The fine set of American fresh-water shells is 

 displayed in the gallery flat cases. The cases which contained 

 the general collection of minerals have been re-painted, and the
