Three sources of sulphurous acid were then experimented with, viz., the burning of sulphur, liquefied sulphurous acid, and the burning of sulphide of carbon. The rooms were closed for twenty-four hours, and tubes containing different proto-organisms, and particularly the comma bacillus made known by Koch, were placed therein, along with other tubes containing vaccine lymph.
Why should we not regard it as the cause of the black tint when the maggots have liquefied the boletes which turn blue? The others, those with the white flesh, the edible bolete, for instance, do not assume this asphalty appearance once they are liquefied by the grubs.
Earths may be metals or fossils; metals being defined as hard bodies, generated in the earth or in its veins, which can be beaten out by a hammer, and softened or liquefied by heat; while fossils include all other inanimate objects.
Between its two stationary divisions moved a current of promenaders, with some such effect as if the colors of a lovely garden should have liquefied and flowed in mingled rose and lilac, pink and yellow, and white and orange, and all the middle tints of modern millinery.
"I am in hopes to put in fifty or sixty bullets at a time without making the arm too heavy, and that would suffice, considering that the replacement of the mass of projectiles requires no appreciable time, while the supply of explosive, liquefied air suffices for three hundred discharges.
Tietkens gave each of these natives a small piece of sugar, with which they seemed perfectly charmed, and in consequence patted the seat of their intellectual that is to say, digestive organs with great gusto, as the saccharine morsels liquefied in their mouths. They seemed highly pleased with the appearance and antics of my little dog, who both sat and stood up at command in the midst of them.
'Dear Sir, The oil you noticed yesterday turns out to be liquid chlorine. 'Yours faithfully, 'M. Faraday. The gas had been liquefied by its own pressure. Faraday then tried compression with a syringe, and succeeded thus in liquefying the gas. To the published account of this experiment Davy added the following note: 'In desiring Mr.
The process as described by Theophilus is as follows: "Compose the niello in this manner; take pure silver and divide it into equal parts, adding to it a third part of pure copper, and taking yellow sulphur, break it very small... and when you have liquefied the silver with the copper, stir it evenly with charcoal, and instantly pour into it lead and sulphur."
I have told you that a gasified liquid, or a liquefied solid, or most of all a gasified solid, contains such heat, and if reconverted into liquid and solid forms respectively, that heat is evolved, or becomes sensible heat, and then it can be decidedly felt and indicated by the thermometer. Take the case of a liquid suddenly solidifying.
In the course of these studies it became evident to them that the presence of argon alone did not fully account for all the phenomena they observed in handling liquefied air, and in 1898 Professor Ramsay was again able to electrify his audience at the Royal Society by the announcement of the discovery, in pretty rapid succession, of three other elementary substances as constituents of the atmosphere, these three being the ones just referred to krypton, neon, and zenon.
