shortly after ; proof of a distinct species from the pole-cat or 

 the martin ; one of these, fed with eggs and flesh, let them 

 putrefy before it touched either ; in Siberia, taken in traps 

 baited with flesh ; and in Norway, shot with blunt arrows, 

 or taken in traps ; sometimes found white in Great Britain, 

 and is then called white weasel ; its fur among us of no value,

Eyes, opened by the infant the moment of its birth, i. 389. 

 Particularly in them the passions are painted, 412. Differ- 

 ent colours of the eye, whence they arise ; eyes of oxen are 

 brown ; those of sheep of a water colour ; of goats are grey ; 

 and those of most white animals are red ; distance between 

 the eyes less in man than in any other animal, 413. In 

 what circumstances women with child are said to be all 

 mouth and eyes ; the lower eyelids, in women with child, 

 drawn downwards, 431. Of all parts the animal has double, 

 the eyes produced soonest ; privations of feeling and sight 

 would misrepresent the situation and number of all things 

 around us ; two contribute to distinct and extensive vision ; 

 both eyes see round the object, and give it that heightened 

 relief which no painting can attain to ; in either is there a 

 point which has no vision, the defect is corrected by having 

 the organ double ; easy experiment to be convinced of it ; 

 objects at a distance are rarely equal in both eyes ; the best 

 eyes see objects largest ; infants, having their eyes less, must 

 see objects smaller in proportion ; when we look at an object 

 extremely brilliant, vision becomes indistinct, and why ; how 

 far the eye can accommodate itself to darkness ; remarkable 

 instance of it in a major under King Charles I. ii. 19. 

 Whence have arisen the small eyes of the Tartars and 

 Chinese, 95. Eastern poets compare the eyes of their mis-
