Another indication of cure, requires such medicines, as by lining the intestines with mucilaginous substances, or with such as consist of smooth particles, or which chemically destroy the acrimony of their contents, may prevent the too great action of the intestinal absorbents.
If nitrous oxid anesthesia and sleep are chemically identical, then we have a further clue to one of the primary mechanisms of life itself; and as a practical corollary one might be able to produce artificial sleep which would closely resemble normal sleep, but which would have this advantage, that by using an anesthetic which interferes with oxidation the brain-cells might be reconstructed after physical fatigue, after emotional strain, or after the depression of disease.
"Behold," they said, "in the chemist's retort the same matter is produced chemically that is produced in the body of the animal, without the direction of a hidden vital force, which, if it is not necessary in the one case, neither is it necessary in the other." Any one who had given the matter careful consideration could even at that time have known where the "ignorant" really were.
For a time it was thought that the use of chemically prepared paper would prove a safeguard, because any erasure or alteration would show immediately. The chemicals used in its composition would make the ink run if acids were used to change the figures. But among the check-raisers there were chemists just as clever as the chemists who devised the prepared paper.
Liebig insisted that all albuminoid bodies were in a state of chemically unstable equilibrium, and if left to themselves would fall to pieces without any need of the action of microscopic organisms.
Three to five one-thousandths of a gram, or six one-hundredths of a grain, are very dangerous. More than that, the poisoning differs from most poisons in the long time that elapses between the taking of it and the first evidences of its effects. "Muscarin," Kennedy concluded, "has been chemically investigated more often than any other mushroom poison and a perfect antidote has been discovered.
From the point of view of the tree, this benefit of injury would depend upon how long the fowls were kept around the tree and the maintenance of them in such a way that the soil should not become out of condition physically or too rich chemically for the satisfactory performance of the tree.
The people of Venus are widely different chemically; the bacteria that can make a Venerian deathly ill is killed the instant it enters our body, or else it starves to death because it can't find the kind of chemical food it needs to live. And the same thing happens when a Venerian is attacked by an Earthly microorganism.
Under my arm was a popular novel and between the pages of this lay a sheet of special lotion paper, chemically treated in a way known only to the German Secret Service and capable of taking a quick clean print of anything written in pencil or ink. As I lifted the dossier from the kiste I noticed that it was embossed on a greenish white paper, not unlike a bank of England note in color.
Chemically it is composed of various proteids, fats, carbohydrates, etc., and these in turn of but very few elements, all of which are common, and none of which are peculiar to protoplasm itself. And yet its essential properties, its mechanical as well as its chemical make-up, have baffled the resources of our wisest men with all their retorts and microscopes and other instruments of precision.
