November 16. — The President (N. H. Foster, M.B.O.U.) delivered his 

 inaugural address on "The Birds of Hillsborough," before a large 

 audience. He said that for some j'ears past he had kept a careful record 

 of all the birds observed within a radius of some 3 or 4 miles from the 

 village of Hillsborough, Co. Down. He considered this area was 

 rich in bird life to an extent quite above the average, possessing as it did 

 a great variety of ideal haunts for birds of various habits. The elevation 

 of the district varied from about ico feet above the sea level on the north 

 to 596 feet on the south. vSince he had kept this record of the birds 

 observed in the neighbourhood, he had noticed 93 species out of 231 

 recorded from the N. E. of Ireland. The yearly list yielded about 77 

 species with a monthly average of about 52, the summer months giving 

 a large preponderence over those of winter. Of the 93 species observed 

 he had proof of the nesting of 68 within the district, IMr. Foster then 

 gave a detailed account of all the various species he had observed. The 

 lecture was illustrated by 50 lantern slides, and at the close was discussed 

 by R. Patterson, F.L.S., B. Hobson, J. N. Milne, and H. I.. Orr. The 

 election of 2 new members concluded the proceedings.
