84 accounts, etc., of the british museum. 



Central Hall. 

 A new case has been added to those placed in the body of the 

 hall illustrating general principles in Natural History. It con- 

 tains a beautiful group of ptarmigan, willow grouse, mountain 

 or variable hare, ermine, and weasel, from Norway in their 

 winter dress, showing the adaptation of their colour at that 

 season to that of the snow with which the ground is covered. 

 A group of the same species of animals from the same locality 

 in summer, arranged amid their natural surroundings, is in 

 course of preparation. For these attractive and instructive 

 specimens the Museum is indebted to the cordial aid of 

 Dr. R. Collett, of Christiania. Numerous additions have been 

 made to the morphological series arranged in the alcoves 

 round the hall.
