own species : in China, India, the Philippine Islands, and 

 over the East, cock-fighting the sport and amusement of 

 kings and princes: cocks in China as bold, or bolder, 

 than ours, and of more strength with less weight : its great 

 courage proceeds from being the most salacious of all birds : 

 a single cock suffices for a dozen hens, and is the only ani- 

 mal whose spirits are not abated by indulgence : soon grows 

 old, and in three or four years becomes unfit for purposes 

 of impregnation : how long cocks live, left to themselves, 

 not well ascertained: AMrovandus makes their age to be 

 ten years: are injured, as Linnaeus asserts, by elder berries, 

 iv. 128. The black chiefly found in heathy mountains, and 

 piny forests, 160. Cock of the wood, 162. 



Cockle, a bivalved shell-fish, v. 239. 



Cod, from the banks of Newfoundland, pursues the whiting, 

 which flies before it to the southern shores of Spain, v. 13. 

 Spawns in one season, as Lewenhoeck asserts, above nine 

 millions of eggs or pease, contained in a single roe, 22. Its 

 description, 124?. Fishery in Newfoundland, 135. 



Cold, excessive, preserves bodies from corruption, ii. 123. 

 Some fishes rendered so torpid by cold in northern rivers, 

 as to be frozen up in the masses of ice, where they continue 

 for months together, without life or sensation, prisoners of 

 congelation, waiting a warmer sun to restore them to life 

 and liberty, v. 153. 



Collar-bones, what animals have them, i. 4-29. 



Colour, none refreshes the sight so well as green, i. 13. Of 

 the sea, not from any thing floating in it, but from the dif- 

 ferent reflections of rays of light, 250. Of the blood in the 

 arteries or veins, 283. Different colours of the eye, 413. 

 Hair takes its colour fromjuices flowing through it, 417. That 

 of the object contributes to form an idea of the distance 

 at which it appears, ii. 29. Of all those by which mankind 

 is diversified, our's most beautiful to the eye, and most ad- 

 vantageous, 89. Those changes the African, the Asiatic, or 

 the American undergo, Fn their colour, are but accidental 

 deformities, which might probably be removed, 97. Nothing 

 exceeds the delicate regularity of those of the zebra, 215. 



Comets, their number much greater than that of the planets ; 

 they roll in orbits ; experience has not sufficiently confirm- 

 ed the truth of the investigation abouttheir returning periods, 

 i. 4. 



Complexion, extremity of cold not less productive of a tawny, 

 than that of heat; not easy to conceive how the sun whitens 

 wax and linen, and darkens the human complexion ; the 

 sun not the only cause of darkening it, ii. 93. 



Concretions, scarce an animal, or a part of their bodies, in which 

 concretions are not formed ; experience has found but few
