BRITISH MUSEUM (NATURAL HISTORY) 11 



Marcuswell Maxwell, and presented by the proprietors of The Times, 

 were hung in the Lower Mammal Gallery and the Central Hall. A 

 model of the giant squid, Stenoteuthis caroli, was placed on exhibition 

 in the Shell Gallery. A new exhibit of Annehd worms was completed. 

 Considerable progress was made with the re -arrangement of the Fish 

 Gallery. 



In the Geological Department one large and two small cases contain- 

 ing plesiosaurs were transferred from the Fossil Reptile to the Fossil 

 Fish gallery as the first stage in a re-arrangement of the galleries. 

 Several cases of fishes were moved into the Fossil Reptile gallery in 

 pursuance of the same scheme. The exhibits of fossil man and of 

 British graptohtes were re-arranged. 



In the Mineral Gallery the fine specimen of cupriferous melanterite 

 from Cyprus presented by Mr. J. L. Bruce was mounted in a special 

 air-tight case with mercury seal and set up in a window to be seen by 

 transmitted fight ; and a 299-lb. mass of meteoric iron from Gibeon, 

 presented by the Administration of South West Africa, was mounted in 

 the PaviHon. 



A temporary exhibit of the historical specimens of cinchona in the 

 Department of Botany was arranged in the Central Hall in connexion 

 with the tercentenary of the discovery of quinine. 



Stvdy Collections 



The usual work of labelling, registering, and incorporating specimens 

 continued in all Departments. As in previous years, the Trustees 

 were much indebted to the numerous workers who gave their services 

 voluntarily, many of whom worked continuously throughout the year. 



Research students were given access to the collections in all Depart- 

 ments and assisted in their investigations. 



Progress was made with the re-arrangement of the collections of 

 Primates and Carnivora, and the greater part of the collection of skins 

 of Ungulates was inspected and re -arranged. Work on the Antarctic 

 Polyzoa collected by the " Terra Nova," " Discovery," and " Quest " 

 Expeditions was continued. Among the MoUusca, the Mitridae, 

 Lucinidea, and African freshwater Lamellibranchia were studied. In 

 the Department of Entomology, the transfer of the collections to the 

 new building, and the consequent re -arrangement, involved much time 

 and labour. In addition, the entire collection of the Hymenoptera was 

 re-organized. In the Department of Geology, the Assistant Keeper in 

 charge of fossil reptiles devoted a great part of the year to the examina- 

 tion and comparison of plesiosaur remains in this and other museums. 

 In the Department of Minerals, an apparatus was designed and set up 

 for measuring the vapour -pressure of zeolites. The X-ray method was 

 further employed in other problems, such as that of distinguishing 

 minerals (nephefine and felspar, analcime and leucite) in rock sections. 

 Among plants from many parts of the world, Gossweiler's West African 

 collection was the object of special study in the Botanical Department.
