History and Philosophical Society. Contributed by Ropert Par- 
TERSON, Esq. and JAMEs R. Garrett, Esq. 
Tse contributors of this paper stated that they had prepared it from their 
late friend’s MSS., in consequence of a suggestion which had been made to

had an opportunity of observing the physical features of the North of Ireland.

Supplementary Report on the Fauna of Ireland by the late William 
Thompson, Esq., President of the Belfast Natural History and 
Philosophical Society. 
Robert Patterson and James R. Garrett, Esqs., the two gentlemen by 
whom this communication was brought forward, gave the following explana-

of the British Association held in the years 1840 and 1843, Mr. Thompson 
presented Reports on the Fauna of Ireland, drawn up by him at the request

(1852), his MSS. were—in pursuance of directions contained in his will— 
handed over to the two gentlemen above-named, with a view to publication, 
so as to complete his work on the Natural History of Ireland, thrée vols. of 
which—on the Birds of Ireland—had appeared during the author’s lifetime. 
On examination of these MSS., a memorandum was found containing a list of 
the papers which it had been Mr. Thompson’s intention to submit to the
