ward flefhy parts, which touch when the bill is clofed, 

 are furnifhed wuh teeth, which form the furface of its 

 two ferrated mandibles. The name of preacher has 

 been given to this bird from its ciiflom of perching on 

 the top of a tree above his companions, while they are 

 afleep, and making a noife relembling ill-articu!ated 

 founds, moving his head to the right and left, in order 

 to keep oft the birds of prey from leizing on the others. 

 They are eaiily rendered fo very tame, as to run about 

 in houfes, and come when called. Their ufual food is 

 fruit ; bp.t the tame eat other things, and in general 

 whatever is given them. 



To defcribe all the other extraordinary birds would 

 engage me in a prolixity of little entertainment or ufe ;

 which is alfo the colour of this fkin, but ufually with 

 fomething of a brovv'niih ún¿\. Its bill is well pro- 

 portioned, ñrong, and a little crooked. They are ib 

 numerous and tame in the city, that it is not uncom- 

 mon to fee the ridges of the houfes covered with them. 

 They are alfo very ferviceable, for they clean the city 

 from all kinds of filth and ordure, greedily devouring 

 any dead animal, and, when thefe are wanting, feck 

 other filth. They have fo quick a fcent, that they will 

 fmell at the difiance of three or four leagues * a dead 

 carcafe, and never leave it till they have entirely re- 

 duced it to a llceleton -[-. The infinite number of
