Page 186 - If it consisted in pression or motion, propagated either in an instant, or in time, it would bend into the shadow.

Now I maintain that similar effects take place whenever...
Page 9 - I know not what the world will think of my labours, but to myself it seems that I have been but as a child playing on the sea-shore; now finding some pebble rather more polished, and now some shell rather more agreeably variegated than another, while the immense ocean of truth extended itself unexplored before me.
Page 62 - The riddle of the nebulae was solved. The answer, which had come to us in the light itself, read: Not an aggregation of stars, but a luminous gas.
