254 ZOOLOGICAL SKETCHES. 



weight of five or six pounds, but the whole body can 

 be drawn through a napkin-ring. The legs are very 

 short and remarkably far apart; the occiput tapers

 grown ferret can squeeze its head through a rat-hole, 

 and where the head goes the rest of the body follows

 advance nor retreat, and thus risks falling a prey to his 

 intended victims, which are not slow to take advantage 

 of his " fix." 



Like bears, dogs are by nature far less savage than 

 the /elides, and yet it is from the canine species that

 The mere sight of a stranger biped or quadruped is
