 to chair with astonishing agility for so small a creature. On 

 taking it into my hand, it showed not the least disposition to 

 resent the liberty ; on the contrary, it was very docile. On 

 being set at liberty, it sprang at least two yards on to a table. 

 In the evening I placed my little stranger, with its original

 " rat-like " forms a recognised standard of comparison in zoo- 

 logical, if not in popular, language. 



The British representatives of the Family are divided into 

 two great sections or sub-families, readily distinguished by the 

 character of their molar teeth ; the first of these including the
