He spoke of the object of chemistry as follows: "In submitting to experiments the different substances found in nature, chemistry seeks to decompose these substances, and to get them into such conditions that their various components may be examined separately.
I find it difficult to think so.... You appear to me always to wish to submit your faith to a process which invariably breaks your apparatus and leaves you very much dissatisfied, with your faith still a simple element in you, in spite of your endeavors to analyze or decompose it. Are not, after all, our convictions our only steadfastly grounded faith?
He says that Aristeas appeared at intervals for a number of years after his death. The elder Pliny also speaks of Aristeas, saying that at Proconesus his soul was seen to leave his body in the form of a raven, though he regards the tale as in all probability a fabrication. But when asked how it was the body did not decompose or the man die of hunger, he has no answer to give.
That of which we have here undoubted information, and that which I am labouring to generalise by comparing similar phenomena, such as are to be found over all the earth, is this, That the natural operations of the atmospheric elements decompose the solid rocks, break down the consolidated strata, waste and wash away those loosened materials of the mountains, and thus excavate the valleys, as the channels by which an indefinite quantity of materials are to be transported to the sea for the construction of future continents.
While he is alive the body deliquesces and decays, and the soul always weaves another garment and repairs the waste. But of course, whenever the soul perishes, she must have on her last garment, and this will survive her; and then at length, when the soul is dead, the body will show its native weakness, and quickly decompose and pass away.
Large groups of the simpler animals contain chlorophyll, and decompose carbonic acid under the influence of light, as plants do. Large groups of the simpler plants, as you may observe in the diatoms from any stagnant pool, are no less actively locomotive than the minute creatures classed as animals seen along with them.
The urine will thus be discharged into the hypobromite, which will of course decompose the urea, liberating nitrogen, which will cause the mercury to rise in B. Shake until no further change of level is seen, and mark the level of mercury in B with a rubber band, then remove the cork, draw out the liquid with a pipette, dry out the tube above the mercury with scrap of blotting paper, pour back the mercury drawn out, and repeat the process to be sure that no error was made.
Fibrine, still more intricate in constitution, contains in each atom, 298 atoms of carbon, 40 of nitrogen, 2 of sulphur, 228 of hydrogen, and 92 of oxygen in all, 660 atoms; or, more strictly speaking equivalents. And these two substances are so unstable as to decompose at quite ordinary temperatures; as that to which the outside of a joint of roast meat is exposed.
Except in the 'gulches' and the deep holes between the hills, the island is covered with lava, in many places of so recent a deposit that it has not yet had time to decompose, and there is consequently only a thin layer of soil on its surface.
Febrile, or digestive disorders, or any condition that may interfere with feeding, may cause this disorder. In the latter cases the mucous membrane of the mouth is not cleansed by the saliva. Particles of feed may decompose and irritating organisms set up an inflammation.
