REPORT OF THE COUNCIL 
OF THE 
YORKSHIRE PHILOSOPHICAL SOCIETY, 
Feb. 1st, 1853. 
The Thirtieth Annual Report of the Yorkshire Philosophical 
Society, which it is now the duty of the Council to present, 
will record an undiminished flow of donations to the Museum, 
and a financial statement in which the income exceeds the 
expenditure. 
During the year 1852, the donations to the Geological 
department of the Museum have been more than usually valua¬ 
ble. Of these, the most important is a very remarkable 
Plesiosaurus from Lofthouse, presented by the Earl of Zetland, 
an acquisition acceptable, not only because the Society pre¬ 
viously possessed nothing but plaster casts to illustrate this 
very extraordinary extinct type of Saurians, but also because, 
the lias of the Yorkshire coast having become celebrated as a 
resting place for the remains of these reptiles, it was very 
desirable that one specimen at least should be seen in the 
Museum of the Yorkshire Philosophical Society. 
Professor Phillips has already made this fine specimen (to 
which he has assigned the name of Plesiosaurus Zetlandicus) 
the subject of a communication to one of the Society’s Monthly 
Meetings, in which he pointed out some remarkable characters 
in the conformation of the head, distinguishing it from all other 
known species of the genus, and contributing, therefore, to
