in many parts of England, and not rare near Tring; 
the European Hamster {Cricetus frumentarius), and 
its skeleton showing the large cheek-pouches, the 
walls of which are connected with muscles arising

numbers, and the persistent wanderings they under- 
take, until they perish entirely. 
Far more remarkable, however, in outward appear-

cannot really fiy, fioat through the air for long 
distances by means of a kind of parachute, i.e. an 
extension of the skin between their legs and generally 
also between the tail and hindlegs. The finest and 
largest of these is the great Chinese Pteromys 
alborufus. 
The next case, the last in this line, is the corner 
case, containing on the top the heads of 
Deer and Roe, 
and also some entire mounted specimens of these 
animals. We see here also a black Roebuck, a 
variety not very rare in certain parts of Germany. 
The Roe {Cervus capreolus) is common in Scotland, 
but not so plentiful as in some parts of Germany,

is rightly considered a firstrate sport. Below the 
Deer two species of the Wombat (Phascolomys) are
