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-

 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
