Strona 225 - The stars shall fade away, the sun himself Grow dim with age, and Nature sink in years, But thou shalt flourish in immortal youth, Unhurt amidst the war of elements, The wreck of matter, and the crush of worlds.

Strona 168 - ... turns red and not blue. An interesting question remains behind. To what kind of small particles — dispersing short waves in preference — is the heavenly azure due ? That small particles of saline or other solid matter, including organic germs, play a part, cannot be doubted, and to them may be attributed much of the bluish haze by which the moderately distant landscape is often suffused. But it seems certain that the very molecules of air themselves are competent to scatter a blue light not...
Strona 71 - To call a body which is not known to contain oxygen and which cannot contain muriatic acid, oxymuriatic acid, is contrary to the principles of that nomenclature in which it is adopted ; and an alteration of it seems necessary to assist the progress of discussion, and to diffuse just ideas on the subject.
Strona 71 - I admitted ammoniacal gas over mercury to a small quantity of the liquor of Libavius; it was absorbed with great heat, and no gas was generated; a solid result was obtained, which was of a dull white colour ; some of it was heated, to ascertain if it contained oxide of tin ; but the whole volatilized, producing dense pungent fumes. Another experiment of the same kind, made with great care, and in which ammonia was used in great excess, proved that the liquor of Libavius cannot be decompounded by...

Strona 71 - ... that the azote of the ammonia was unchanged in the operation. Some authors continue to write and speak with scepticism on the subject, and demand stronger evidence of chlorine being undecompounded. These evidences it is impossible to give. It has resisted all attempts at decomposition. In this respect, it agrees with gold, and silver, and hydrogen, and oxygen. Persons may doubt, whether these are elementary bodies ; but it is not philosophical to doubt, whether they have not been resolved into...
Strona 168 - ... few per cent.* It has been pointed out by Dr. Schuster that the introduction of the raised number into the formula almost exactly accounts for the degree of atmospheric transparency observed at high elevations in the United States, apparently justifying to the full the inference that the normal blue of the sky is due to molecular scattering. But. although there is no reason to anticipate that this general conclusion will be upset, it should not be overlooked that a molecule, especially a diatomic...
