REPORT OF THE COUNCIL 
OF THE 
YORKSHIRE PHILOSOPHICAL SOCIETY, 
Feb. 5, 1856. 
In presenting to the Annual Meeting the Report for the 
past year, the Council will first relate the ordinary operations 
of the Society, and then advert to the results of some important 
changes in its Laws, which have been carried into effect within 
the year. 
Numerous and valuable additions have been made during 
the past year to the Natural History Collections, both by 
donation and by exchange. Mr. Joseph Clark, of Cincinnati, 
who seldom allows a twelvemonth to pass without some proof 
of the interest which he takes in the progress of the Society’s 
Collections, has sent various American fossils and recent fresh¬ 
water shells, in extension of the beautiful series of specimens 
given by him in former years. A cast of the celebrated 
Plesiosaurus Macrocephalus belonging to the Earl of Ennis¬ 
killen, has been received from the Hull Philosophical Society 
in exchange for a duplicate specimen of the skull and horns of the 
extinct Irish Deer. The Committee of the York Medical School 
have presented a very perfect specimen of the skull of the Bos 
longifrons of Owen, found in digging a canal near Pocklington; 
and Mr. Sharpin, a portion of the thigh bone of the Deinornis, 
or great extinct wingless bird of New Zealand—a valuable addi¬ 
tion to the casts of bones of this bird, previously presented by 
the Council of the College of Surgeons. From H. P. Cholmeley,
