We have seen how the theory of the solar system was slowly developed by the constant efforts of the human mind to find out what are the rules of cause and effect by which our conception of the present universe and its development seems to be bound.
The selection of the best substance to be used as a standard for acid solutions has been the subject of much controversy. Chem. 2HNaCO > Na CO + H O + CO and without loss of any carbon dioxide from the sodium carbonate, such as may occur at higher temperatures. The process is carried out as described below.
In 1881 the export amounted to $150,000, of which three-fourths came to America. Chem. Zeit.
Every estancia, or farming estate, has one attached to it. The hovels of the Indians are thus called. Report of the Agricult. Chem. Assoc. in the Agricult. Gazette, 1845, p. 93.

During laboratory work, a burner is placed under the retort and the sulphur kept hot, so that its temperature may be quickly raised to the boiling-point when the gas is required. From time to time it is necessary to replenish the retort with sulphur and to remove the condensed portions from the neck. Chem. News.
The large temple, built with barbarian rudeness, and ornamented with the Phoenician palm-branch, was on somewhat of a Roman plan, with a circular end to every room. But it was dedicated to the chief god of Egypt, and is even yet called by its Greek name Hagia Chem, the temple of Chem.
At present, the ship's personnel were existing almost entirely on tanked air, but within two weeks one of the three air-restoration projects on the satellite either hers, in which hydroponic plants and algae were the basic purifiers; or projects in the chem and physics labs would have to be already functioning in the job, or extra shuttles would have to be devoted to air transportation until they were ready.
Cockayne said, sternly; "and we'll go to-morrow, directly after breakfast, and spend a nice morning looking over the things." "But there are really two or three items, my dear, Sophy has forgotten.
