Rising, at last, Rue turned to Bergan, and made him a low, reverential courtesy. "To Berganton! What had you to do with Berganton, I should like to know?" The main body of the volume is divided into two parts攖he first dealing with observations made in and before 1772, the second with observations made in the year 1773 and in the beginning of 1774. In the outset Priestley finds himself at a disadvantage in regard to the only terms at that time in vogue for the factitious airs, viz., fixed, mephitic and inflammable, which, he rightly says, are not sufficiently characteristic and distinct. Strictly speaking, any two of these terms might be applied to any one of the 渁irs?then known. The inflammable air from metals, as well as choke damp, is noxious, and therefore mephitic, as is fixed air, and since the inflammable airs are, apparently, capable of being imbibed by certain substances they may equally be considered fixable. The term fixed air had, however, acquired a distinctive meaning, and rather than introduce a new term or change the signification of an old one, he would, with his contemporaries, restrict the term to the air which had been made the subject of Black檚 memorable investigation. The first paper in this section deals with fixed air; it is practically a reprint of that in the 177 Phil. Trans. and which has already been described in sufficient detail. In the course of his experiments he says he once thought that the readiest method of procuring fixed air, and in sufficient purity, would be to heat pounded lime-stone in a gun barrel, 渕aking it pass through the stem of a tobacco pipe or a glass tube carefully luted to the orifice of it.? "A perplexity that ends so pleasantly deserves thanks rather than pardon," returned Bergan. "For the best of reasons,攈e does not want to receive them. He prefers to be able to say that he hears nothing, and knows nothing. Therefore, you will readily understand that nothing is to be said, or even hinted, to him. He puts the matter in my hands, and you are responsible to me only." � 国产成 人 综合 亚洲,成 人 国产综合,成 人 国产综合 "What! whether his cause be right or wrong?" And yet, how strong a hold, after all, had both master and mansion upon his heart! Some time, surely, when he should have won fame and fortune enough to be above all suspicion of self-seeking, he might come back to visit them, and see what could be done for both. � � "If it hurts your conscience, you can pass it over to him," rejoined Major Bergan, with grim humor.
