Now, the velocity of wave propagation can be seen, without the aid of any mathematical analysis, to depend on the elasticity of the medium and its density; for we can see that if a medium is highly elastic the disturbance would be …

The more important fundamental laws and facts of physical science have all been discovered, and these are now so firmly established that the possibility of their ever being supplanted in consequence of new discoveries is exceedingly remote.

Many instances might be cited, but these will suffice to justify the statement that "our future discoveries must be looked for in the sixth place of decimals."

It appears, from all that precedes, reasonably certain that if there be any relative motion between the earth and the luminiferous ether, it must be small; quite small enough entirely to refute Fresnel's explanation of aberration.

I look'd far back into the past, and lo! in bright array, I saw, as in a dream, the forms of ages pass'd away. It was a stately convent, with its old and lofty walls, And gardens with their broad green walks, where soft the footstep falls.
