193 ÆäÀÌÁö - Institution, which will be awarded annually or biennially, for important contributions to our knowledge of the nature and properties of atmospheric air, or for practical applications of our existing knowledge of them to the welfare of mankind.
2 ÆäÀÌÁö - Make corrections of the final reading of the burette precisely as in the standardization. "Gold, silver, lead, copper, iron, manganese and the ordinary constituents of ores do not interfere with the above scheme. Cadmium behaves like zinc. When known to be present it may be removed, together with the copper, by the proper treatment with...

199 ÆäÀÌÁö - M'Kendrick had tried the effect of these low temperatures upon the spores of microbic organisms, by submitting in sealed glass tubes blood, milk, flesh, and such-like substances, for one hour to a temperature of — 182¡Æ C., and subsequently keeping them at blood heat for some days. The tubes on being opened were all putrid. Seeds also withstood the action of a similar amount of cold. He thought, therefore, that this experiment had proved the possibility of Lord Kelvin's suggestion, that life might...
2 ÆäÀÌÁö - As soon as a brown tinge is obtained note the reading of the burette, and then wait a minute or two and observe if one or more of the previous tests do not also develop a brown tinge.
38 ÆäÀÌÁö - ... Measurements of the rate of explosion can be employed for determining the course of some chemical changes. In the explosion of a volatile carbon compound with oxygen, the gaseous carbon appears to burn first to carbonic oxide, and afterwards, if oxygen is present in excess, the carbonic oxide first formed burns to carbonic acid. 6. The theory proposed by Berthelot— that in the explosion wave the flame travels at the mean velocity of the products of combustion— although in agreement with the...
199 ÆäÀÌÁö - At such low temperatures they semed to be drawing near what might be called " the death of matter," so far as chemical aftion was concerned ; liquid oxygen, for instance, had no anión upon a piece of phosphorus and potassium or sodium dropped into it ; and once he thought and publicly stated, that at such temperatures all chemical action ceased. That statement required some qualification, because a photographic plate placed in liquid oxygen could be acted upon by radiant energy, and at a temperature...
