142 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



progress, and descriptions have been written of the cordierite- and 

 sillimanite-gneisses, epidote-rocks, graphitic and mica-schists, and 

 some of the gneisses. 



Rock-specimens collected by Captain Lynes in Morocco have 

 been examined. 



In the Chemical Laboratory complete quantitative analyses have 

 been made of the meteorites Adare and Mt. Ayliff, and quantitative 

 determinations have been made of the amount and composition of 

 the nickeliferous iron in the meteorites Ensisheim, Felix, Henderson- 

 ville, and Simondium. Many minerals, including specimens of 

 tinstone from Nigeria, have been qualitatively analysed.

Proofs of the General Library Catalogue (Supplement) have 

 been read and checked against the slip-catalogue in the Department. 



Accessions. — 2S volumes of separate works, 12 parts of continua- 

 tions,. 24 periodicals (in 311 volumes and parts), 53 memoirs and
