These are what we have mainly to look out for, the carbonaceous foods usually being over abundant.
From the above experiments it is inferred that a supply of carbonaceous matter does not increase the crop of barley.
The carbonaceous residuum is occasionally slightly acted upon.
The bulk of the grain was corn in the carbonaceous, and wheat in the nitrogenous ration.
When nitre, for instance, is burned with carbonaceous matter, the product is carbonate of potash.
Next in point of altitude, is the series of dark, carbonaceous, shelly slate rock.
I could not expect shells, for they never occur in this formation; but lignite or carbonaceous shale ought to be found.
The blacks and browns were mixtures of carbonaceous matter, with the ores of iron or manganese.
carbonaceous rocks, composed largely of hydrocarbon compounds.
The ores of iron, which are all oxides, are reduced by exposing them to the action of carbonaceous matter, at a high temperature.
A naturally abundant, nonmetallic element that occurs in all organic compounds and can be found in all known forms of life. Diamonds and graphite are pure forms, and carbon is a major constituent of coal, petroleum, and natural gas. Carbon generally forms four covalent bonds with other atoms in larger molecules. Atomic number 6; atomic weight 12.011; sublimation point above 3,500°C; boiling point 4,827°C; specific gravity of amorphous carbon 1.8 to 2.1, of diamond 3.15 to 3.53, of graphite 1.9 to 2.3; valence 2, 3, 4.
