A considerable number of objects have been acquired for the Museum 
of the Academy within the past year. The treasure-trove regulations 
are found to work for our advantage ; and through their operation we 
have obtained, in particular, a large collection of silver coins of the 
reigns of Elizabeth, James I., and Charles I. 
The O'Brien Yase, which had been for some time deposited in 
the Bank of Ireland, has been removed to the Academy's house, and 
placed in the strong room. 
The Ogham-inscribed stones, ten in number, purchased from the 
representatives of the late Mr. Windele, have been arranged in the 
crypt, one being set vertically in the floor, and the others placed either 
on iron stands in the bays at. the south side, or on the dwarf walls form- 
ing the bays. These stones are now all easy of access, and, in the 
daytime, have the advantage of a light well adapted to the examination 
of their respective inscriptions. 
It is much to be regretted that the crypt, which has been devoted 
to the purpose of a Lapidary Museum, is not provided with a convenient 
entrance, and is destitute of proper arrangements for its heating and 
lighting with gas. Representations on the subject of these defects 
have been made to the Board of Works, but as yet without result. 
Paper casts have been made of the Ogham inscribed stones (23 in 
number) deposited in the crypt. 
The placing of our collection of Antiquities in the new Museum 
Rooms has been actively proceeded with, and is now nearly completed. 
Horizontal mahogany cases, glazed with plate glass and enclosing 
suitable desk trays, have been adapted to the tops of the tables in the 
long room. In one of these cases, (Ko. 23), the greater portion of the
