2 5 ZOOLOGICAL SKETCHES.

 the leonine calmness of a mastiff among a swarm of 

 Skye terriers. 



His intrepidity seems to refute the favorite argument 

 of the anti-vegetarians, for the chacma subsists on ber-

 The screams that accompany his fits of trepidation make 

 him a rather undesirable pet, for the constant exercise of 

 his vocal apparatus has developed that organ to a degree 

 out of all proportion to the size of the little alarmist. 

 Frederick Gerstaecker, who shipped a boxful of these

In his lucid moods the Cebus is, on the whole, an
