Nightingale, a bird of the sparrow kind, iv. 255. Description 

 of its melody by Pliny, 264. Its residence ; for weeks to- 

 gether, undisturbed, it sits upon the same tree; its nest, 

 and eggs ; its song in captivity not so alluring ; Gesner says 

 Jt is possessed of a faculty of talking; story related by him 

 in proof of this assertion ; its food, and in what manner they 

 must be kept; manner of catching the nightingale, and ma- 

 naging them when caught ; the black-cap, called by some 

 the mock-nightingale, 265. 



Nile, its course ; its sources ascertained by missionaries ; takes 

 its rise in the kingdom of Goam ; receives many lesser rivers ;

 of its annual overflowings ; time of their increase and de- 

 crease more inconsiderable now than in the time of the an- 

 cients, i. 183. Mr Bruce's account of its source and pro- 

 gress, 184.

 sent an actual deformity, i. 408. The form of the nose, 

 and its advanced position, peculiar to the human visage ;

 Tartar seen in Europe with little more than two holes 

 through which to breathe, 418. Whence originally may 

 have come the flat noses of the blacks, ii. 95. 



Nostrils, wide, add a great deal to the bold and resolute air 

 of the countenance, i. 418.
