Reeve, name given to the female of the Ruff, iv. 349. ' 



Rein- deer, killed by eight Englishmen upon the coast of 

 Greenland, for their subsistence, remained sweet eight 

 months, without any salt whatever, i. 268. For the de_- 

 scription of this animal, see Deer. 



Relievo, painters can never fully imitate that bold relievo 

 which both eyes give to the object, ii. 23. 



Remora, the sucking-fish, it sticks to the shark and drains away 

 its moisture; the seamen believe it attends the shark to 

 point out prey, and apprize him of danger ; for this reason 

 it is called the Shark's pilot, v. 73. 



Reproduction, the first discovery of the power of reproduc- 

 tion in animals owing to Mr Trembley ; experiments made 

 to this purpose, vi. 179. 



Reptiles grow to a prodigious size in the internal parts of South 

 America and Africa, and why, i. 351. Many of the more 

 humble kinds not only confined to one country, but to a 

 plant ; nay, even to a leaf; entirely assimilated to the plant 

 they feed on ; assume its colour, and medicinal properties ; 

 taken from that, they instantly die ; infinite numbers of them 

 not seen in this part of the world, and why, 352. 



Respiration in fishes, general method of explaining it, v. 15. 

 particularly in that of the whale kind, 28. 



Rhinoceros, a ruminating animal, ii. 225. Not afraid singly 

 to oppose the lion, 409. Next to the elephant the most 

 powerful of animals ; general outline of it ; the elephant de- 

 feated by it ; its horn sometimes found from three to three 

 feet and a half long ; this horn composed of the most solid 

 substance, and pointed so as to inflict the most fatal wounds; 

 fabulous reports of this animal ; description of its tongue by 

 L' Avocat ; a rhinoceros sent from Bengal to London, not 

 above two years old, cost near a thousand pounds for his 

 conveyance and food ; how it was fed ; of a gentle disposi- 

 tion, permitted itself to be touched and handled by all visi- 

 tors, attempting no mischief but when abused, or hungry ; 

 no method of appeasing its fury then but by giving it some- 

 thing to eat : when angry, it jumped against the walls of the 

 room with great violence ; its age ; its food ; places where 

 found ; in some parts of Asia these animals are tamed, and 

 led into the field to strike terror into the enemy, but are as 

 dangerous to the employers ; method of taking them ; some 

 found in Africa with a double horn, one above the other ; 

 many medicinal virtues ascribed to this horn when taken in 

 powder, without any foundation, iii. 357, &c. 



Rivers, all our greatest find their source among mountains, i. 

 123. Make their own beds, and level the bottom of their 

 channels ; rivers dig and widen themselves to a certain de-

 when the adjacent valley is overflown, and why ; their sinuo-
