Chemistry also received valuable extensions of its field. Dr. John Mayow published new facts respecting nitre, and on the phenomena of respiration and combustion, as revealed by experiments on this and other substances. At the commencement of the eighteenth century Stahl, a German chemist, propounded his theory of phlogiston as the principle of combustion, which was only exploded by the further discoveries of Dr. Black, Cavendish, and Priestley. Soon after, Dr. Hales threw new light on a?riform bodies, or, as they are now termed, gases; and finally, Dr. Black demonstrated the presence of a gas in magnesia, lime, and the alkalies, which had long before been noticed by Van Helmont, but had been forgotten. This was then termed fixed air, but has now acquired the name of carbonic acid gas, or carbon dioxide. At the end of this period chemistry was extensively studied, and was rapidly revealing its secrets.The general kept his own counsel then, but afterward, when it was all over, he confessed,not to the rejoicing reporter who was making columns out of him for the papers of this, and even of many another, land,but to the friends who had in some measure understood and believed in him, that the strain and responsibility had all but worn him out. And he was no frail man, this mighty hunter of the plains.

Of the fruitful earth, like a goblin elf,She waited, too, made silent by sudden realization of how futile anything that she might say would be. "I am glad to see you again," she faltered; "it is four years since Black River and the cloud-burst." She was angry at her own stupidity and want of resource, and her tone was more casual than she meant it to be.It was the beginning of a self-imposed Coventry. He sent in a demand for a court of inquiry, and Brewster, with much show of reluctance and leniency, preferred charges.
