172 A HAND-BOOK OF THE MANAGEMENT OF ANIMALS 



mild cases the animals recover at the approach of warm weather; in 

 others the paralysis increases, some other disease, such as inflammation of 

 the lungs or diarrhcea supervenes, and the animals die. Ulceration of 

 the mucous membrane of the gums and the tongue has been known to 

 cause the death of a wallaby. 



An apparently healthy wallaby died after having been dull for 

 three or four days, during which time it scarcely ate or drank. On an 

 autopsy being performed a large cancerous tumour was found in the 

 pyloric end of the stomach. In the stomach of another wallaby was 

 found a large ball of wallaby's hair, deeply imbedded in the substance 

 of the mucous membrane. 



Scrofula occasioned the death of two wallabies, one of them born 

 and bred in captivity. In both of them the glands of the neck were 

 suppurated. 



Observations on the habits of Kangaroos and Wallabies. 



Generally they are timid and harmless creatures, though capable 

 of inflicting serious wounds in self-defence. They sometimes fight 

 among themselves by hugging each other, trying to strangle the 

 adversary between the fore limbs ; and at the same time biting and 

 fleecing it. The ball of hair that was found in the stomach of a wallaby 

 was probably the result of one or more fights like this. They are very 

 inquisitive, though timid, especially the wallaby. Some of them are often 

 observed to follow a visitor from one end of the enclosure to the other, 

 or to remain in one spot for minutes together watching every movement.
