Sheep, their eyes of a water-colour, i. 4-13. The author saw 

 one that would eat flesh, ii. 165. Proper care taken of the 

 animal produces favourable alterations in the fleeces, 167. 

 In the domestic state, stupid, defenceless, and inoffensive : 

 made so by human art alone : its description: those living 

 upon fertile pasture, growing fat, become feeble j those 

 without horns more dull and heavy : those with longest and 

 finest fleeces most subject to disorders : the goat, resem- 

 bling them, much their superior : they propagate together, 

 as of one family : distinguished from deer : these annually 

 shedding the horns, while the permanence in the former 

 draws an exact line between their kinds : do not appear 

 to have been bred in early times in Britain : no country 

 produces such sheep as England, larger fleeces, or better 

 for clothing : sheep without horns the best sort, and 

 why : in its noblest state in the African desert, or the ex- 

 tensive plains of Siberia : in the savage state : the woolly 

 sheep is only in Europe, and in the temperate provinces of 

 Asia : transported into warmer countries, loses the wool 

 and fertility, and the flesh its flavour : subsists in cold coun- 

 tries, but not a natural inhabitant of them : the Iceland 

 sheep have four, and sometimes eight horns : its wool infe- 

 rior to the common sheep : with broad tails, that weigh 

 from twenty to thirty pounds, and sometimes supported : 

 those called strepsicheros, a native of the Archipelago : 

 Guinea-sheep described, ii. 254-. They eat three hundred 

 and eighty-seven plants, and reject a hundred and forty- 

 one, 369. Have eight teeth in the lower jaw : are shed 

 and replaced at different periods : some breeds in England 

 never change teeth, and are supposed old a year or two 

 before the rest, 259. Bring forth one or two at a time, 

 sometimes three or four: the third lamb supposed the best : 

 bear their young five months, 260. The intestines thirty 

 times the length of their body, 396. In Syria and Persia, 

 remarkable for fine gloss, length, and softness of hair, 398.

Sheldrake, a variety of the pond-duck, supposed a native of 

 England, iv. 421. 



Shells, (fossil) found in all places near to and distant from the 

 sea, upon the surface of the earth, on the tops of mountains, 

 or at different depths, digging for marble, chalk, or other 

 terrestrial matters, so compact as to preserve these shells 

 from decay, i. 14<. Long considered as mere productions 

 of the earth, never inhabited by fish ; some have not their 

 fellows in the ocean ; but all have the properties of animal, 

 not of mineral nature, their weight the same with those 

 upon shore, answer all chemical trials as sea-shells do, and 

 have the same effects in medicinal uses ; various kinds 

 found a hundred miles from the sea ; a continued bed of
