393 ÆäÀÌÁö - 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.
341 ÆäÀÌÁö - 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...
99 ÆäÀÌÁö - 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.
392 ÆäÀÌÁö - Authors of the highest eminence seem to be fully satisfied with the view that each species has been independently created. To my mind it accords better with what we know of the laws impressed on matter by the Creator, that the production and extinction of the past and present inhabitants of the world should have been due to secondary causes, like those determining the birth and death of the individual.
392 ÆäÀÌÁö - I believe that animals are descended from at most only four or five progenitors, and plants from an equal or lesser number.
392 ÆäÀÌÁö - Therefore I should infer from analogy that probably all the organic beings which have ever lived on this earth, have descended from some one primordial form, into which life was first breathed.
21 ÆäÀÌÁö - As nitrous oxide in its extensive operation appears capable of destroying physical pain, it may probably be used with advantage during surgical operations in which no great effusion of blood takes place.
496 ÆäÀÌÁö - 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...
346 ÆäÀÌÁö - 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.
200 ÆäÀÌÁö - Great fleas have little fleas upon their backs to bite 'em, And little fleas have lesser fleas, and so ad infinitum.
