On this occasion he wished not so much to demonstrate certain conclusions, or to make a declaration of his opinions, as to invite discussion and a thoughtful consideration of questions of importance to chemists. Second, Is the determination of the vapor density of a body alone sufficient to determine the weight of the chemical molecule?
Petroleum was at first distilled in a rough way; but now it is done with the utmost care and exactness. The crude oil is pumped into boilers holding six hundred barrels or more. The fires are started, and the oil soon begins to turn into vapor. This vapor passes through coils of pipe or long, straight, parallel pipes.
All the sanguinary, sacrilegious, execrable ambition of the worst popes seemed written in fiery characters on the brow of this son of Ignatius. A morbid desire of rule seemed to stir up the Jesuit's impure blood; he was bathed in a burning sweat, and a kind of nauseous vapor spread itself round about him.
For miles round fierce flashes of lightning rent the vapor, and at a distance of fully forty miles ghostly corposants gleamed on the rigging of a vessel. These phenomena grew more and more alarming until August 27th, when four explosions of fearful intensity shook earth and sea and air, the third being "far the most violent and productive of the most widespread results."
I refer to the absence of fog or visible vapor in thick woods in full leaf, even when the air of the neighboring open grounds is so heavily charged with condensed vapor as completely to obscure the sun.
Little by little, steeples, white buildings, a gilded cupola, emerged from the mist, and burst forth in a splendid awakening. Then the thousands of tall factory chimneys, towering above that sea of clustered roofs, began with one accord to exhale their quivering vapor, with the energy of a steamer about to sail. Life was beginning anew. Forward, ye wheels of time!
Even to the boy's untrained ear there was a difference, and when he noticed that blood was mixed with the vapor thrown out from the blowhole, his hope revived. The second rush of the whale was easily avoided, and Hank thrust in the lance again. Then, for the first time, the old whaler permitted himself to smile, a long, slow smile.
It was soon apparent that Hawkeye had not magnified the power of the fog, for before they had proceeded twenty yards, it was difficult for the different individuals of the party to distinguish each other in the vapor.
Besides, it was not incessant; there were continual liftings of cloud and vapor, glimpses of clear sky, and a constant changing of tints, from flashing, dewy splendor, through the softness of shining mists, to the glooms of gray clouds, and the blinding, uncompromising rain, so that I would have ridden in a cistern rather than have failed to see it.
The vapor rising from the earth and the sea by evaporation, promoted by dry air, by wind, by diminished pressure, or by heat, is borne along in vesicles so rare as to float on the bosom of the winds, sometimes a grateful shade of clouds, at other times condensed and gravitating in showers of rain. Thus it enriches the soil, or cools the air, or reflects back to the earth its radiated heat.
