160 THE TOWER MENAGERIE. 
Modern naturalists have attempted to distinguish 
several species among the Kanguroos; but as the cha- 
racters on which these are founded consist merely in 
difference of size and slight modifications of colour, a 
much more complete acquaintance with them than we 
yet possess is requisite before they can safely be adopted. 
Our specimens are of a brownish gray above, somewhat 
lighter beneath, with the extremity of the muzzle, the 
back of the ear, the feet, and the upper surface of the 
tail, nearly black, and the front of the throat grayish 
white. Since they have been confined in the Menagerie, 
the female has once produced young; a circumstance by 
no means unfrequent even in this country among those 
which are less restricted of their liberty and are suffered 
to roam at large in a meadow or a park. They are fed, 
like the domesticated Ruminants, upon green herbage 
and hay; and are extremely tame and good tempered.
