In Antiquities, Dr. Petrie has contributed to our Proceed-

was exhibited in the Antiquarian Court of the Great Exhibition,

During the past year, the Academy’s Museum has received several 
most important and valuable additions, by donation as well as by 
purchase. Amongst the donations, we have received from the Com- 
missioners of Public Works, through Mr. Mulvany, a curious col- 
lection of antiquities found in the drainage of Lough Mask; and 
some valuable articles found in Lough Oughter and Lough Gowna,
