INDEX. 231 



the nest to shift for themselves, they keep them with care, 

 and even when adult do not forsake them : the whole brood 

 thus live in a family together : each family afterwards lives 

 apart, and hunt in concert : upon the returning season of 

 courtship this union is at an end, the family parts for ever, 

 each to establish a little household of its own : the manner 

 of flying is always up and down, seldom direct or sideways ; 

 different kinds of this bird, iv. 108. 



Butter, the fat of the manati serves in all cases instead of but- 

 ter, iii. 277. 



Butterfly, some kinds actually live upon nothing, ii. 3. One 

 of the principal ornaments of oriental poetry: in those 

 countries, the insect is larger and more beautiful than with 

 us, vi. 46. Easily distinguished from flies of every other 

 kind by their wings : number and beautiful colours of its 

 wings : butterflies can discover their mates at more than a 

 mile distant : description of the head, corslet, and body : 

 the eyes have not all the same form; but the outward coat 

 has a lustre, in which may be discovered all the colours of 

 the rainbow : when examined closely, it has the appearance 

 of a multiplying-glass : the use of their horns or feelers as 

 yet unknown : use of their trunks : difference between but- 

 terflies and moths: they often perceive the approach of the 

 female at above two miles distance ; by what sense is not 

 easy to conceive : it has no organs for smelling : the female 

 is larger than the male: if disturbed while united, the 

 female flies off with the male on her back, entirely passive 

 upon the occasion : after junction, they deposit their eggs 

 and die : all females of this tribe are impregnated by the 

 male by one aperture, and lay their eggs by another : every 

 butterfly chooses for her brood, instead of the plant most 

 grateful in its winged state, that it has fed upon in its rep- 

 tile form : how they keep their eggs warm, and also entirely 

 concealed : many do not lay till the winter warns them of 

 their approaching end : some continue the whole winter in 

 hollows of trees, and do not provide for posterity until the 

 beginning of April, then leave their retreats, deposit their 

 eggs, and die, 69. 



Buzzard, a sluggish inactive bird, often remains perched whole 

 days upon the same bough : lives more upon frogs, mice, 

 and insects than upon birds : more troublesome to seize : 

 its manner of living in summer : so little capable of instruc- 

 tion, that it is a proverb to call one obstinately ignorant, a 

 buzzard: the honey-buzzard, the moor-buzzard, and the 

 hen-harrier, are of this stupid tribe, and differ chiefly in 

 their size, iv. 106.

 gigantic race of mankind, ii. 113.
