Стр. 393 - There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.
Стр. 341 - In thoughts from the visions of the night, when deep sleep falleth on men, Fear came upon me, and trembling, which made all my bones to shake. Then a spirit passed before my face ; the hair of my flesh stood up...
Стр. 99 - How gloriously her gallant course she goes! Her white wings flying — never from her foes — She walks the waters like a thing of life, And seems to dare the elements to strife.
Стр. 392 - Authors of the highest eminence seem to be fully satisfied with the view that each species has been independently created.

Стр. 496 - That, for instance, in acquiring the sensation of redness, our eyes are affected four hundred and eighty-two millions of millions of times ; of yellowness, five hundred and forty-two millions of millions of times ; and of violet, seven hundred and seven millions of millions of times per second...
Стр. 346 - Trees having this character of wood are rare, and do not exist in the proportion of one to a hundred. The serpentine direction of the fibre, which renders them difficult to split and to work, produces, in the hands of a skilful mechanic, the most beautiful effects of light and shade. These effects are rendered more striking, if, after smoothing the surface of the wood with a double-ironed plane, it is rubbed with a little sulphuric acid, and afterwards anointed with linseed oil.
Стр. 200 - Great fleas have little fleas upon their backs to bite 'em, And little fleas have lesser fleas, and so ad infinitum.
