The oil spread in a thin layer upon the surface of the wine, hinders the evaporation of its alcoholic part, and prevents it from combining with the atmospheric air, which would not only turn the wine sour, but change its constituent parts.

He will send, not the water itself, but the salts obtained by evaporation from the quantity of water necessary for each aquarium.

The juice of thirty-three palms, after evaporation in an iron pan immediately upon each collection, produces one ganta, or (there being four such collections) four gantas, daily; the weekly result being twenty gantas, or two tinajas of sugar, each worth two dollars and a half on the spot.

These two operations, clarification and evaporation by the use of the vacuum, are merely improved methods for doing, on a large scale, what was formerly done by boiling in pans or kettles, on a small scale.

"The amount of water taken from the soil by the trees of a forest and passed into the air by transpiration is not so large as that accumulated in the soil by the diminished evaporation under the branches.

Experts tell us that the percentage of salt and soda is six times as great as in the waters of the Atlantic, and one great advantage of living in its vicinity is the abundance of good, pure salt, which is produced by natural evaporation on its banks.

The water in the outer vessel boils, while that in the inner vessel does not, being kept a little below the temperature of the water from which its heat is obtained, by the constant evaporation at a temperature a little below the boiling point.

For this purpose, a vacuum system is used, making possible a more rapid evaporation with a smaller expenditure of fuel.

Evaporative power of boilers, power generated by evaporation of a cubic foot of water; increase of evaporation due to increased exhaustion in locomotives.

This state of the atmosphere caused a rapid evaporation during the day, and as the evening approached a very copious dew commenced falling, which by sunset was precipitated like a shower of rain.

There is a very thin light fall of snow crystals, but the surface deposit seems to be abating the evaporation for the moment, outpacing the light snowfall.

The amount of water taken up by evaporation into the atmosphere is almost incredible.
