As the result of Carbon monoxide poisoning, as after accidental or attempted suicidal gas inhalation, the memory, especially for the most recent events, is impaired and the patient cannot remember the events as they occur; he passes from moment to moment unconnected to the recent past, though his remote past is clear.
The retort is filled with iron or steel borings, alone if pure hydrogen is required, or cast into balls with pitch if a little carbon monoxide is not a drawback, as in foundry work.
Therefore in every coal-camp had to be another kind of "fire-boss," whose duty it was to guard against another kind of explosions not of carbon monoxide, but of the human soul. The immediate duties of this office in North Valley devolved upon Jeff Cotton, the camp-marshal.
Thomson attempted to separate and determine the quantity of carbon monoxide and hydrocarbons present in the flue gases from various forms of gas stoves and burners, but, like every other observer who has attempted to solve this most difficult problem, he found it so beset with difficulties that he had to abandon it, and contented himself with determining the total amounts of carbon and hydrogen escaping in an unburned condition, experiments which showed that the combustion of gas in stoves for heating purposes is much more incomplete than one had been in the habit of supposing, but his experiments give no clew as to whether the incompletely burned matter consisted of such deleterious gases as carbon monoxide and acetylene, or comparatively harmless gases, such as marsh gas and hydrogen.
Even in man, if the supply of arterial blood be stopped but for a moment, the nerve-mechanism loses its power; if diminished, it correspondingly declines; if, on the contrary, it be increased as when nitrogen monoxide is breathed there is more energetic action. Hence there arises a need of repair, a necessity for rest and sleep.
The details of the experiment indicate that a saving of fuel in the blast furnace could best be accomplished by the use of a very hot blast, introducing some carbon monoxide into the blast, provided, of course, that this gas can be made outside of the blast furnace more cheaply than inside of it.
The energy consumed by the reduction of the ore is almost entirely electrical, only enough carbon being used to unite with the oxygen of the ore to carry it out of the furnace in the form of the carbon monoxide, the aluminum remaining behind. Consequently, the plant necessary to produce aluminum on a large scale involves a large number of the most powerful dynamos.
In effect, the differences between individuals may fundamentally thus be grouped among the differences which distinguish other chemical substances. The difference between water, technically known as hydrogen monoxide, and the antiseptic fluid labeled hydrogen dioxide lies wholly in the possession by the latter of an extra atom of oxygen in its molecules.
At first sight it seems a dangerous experiment to mix a heavy hydrocarbon gas with oxygen, but it must be remembered that although hydrogen and carbon monoxide only need to be mixed with half their own volume of oxygen to give a most explosive mixture, yet as the number of carbon and hydrogen atoms in the combustible gas increase, so does the amount of oxygen needed to give explosion.
Hæmochromogen gives a very characteristic spectrum, and is obtained by reducing alkaline hæmatin by ammonium sulphide. Carbon monoxide hæmoglobin gives a spectrum which resembles that of oxyhæmoglobin, but it is not reduced by ammonium sulphide.
