The experiment was first tried with hydrogen and common air, the oxygen of the air uniting with the hydrogen to form water, leaving the nitrogen of the air still to be accounted for. With pure oxygen and hydrogen, however, Cavendish found that pure water was formed, leaving slight traces of any other, substance which might not be interpreted as being Chemical impurities.
The mind shrinks in dismay at the appalling revelations, and shudders at the possibly of the "human form divine" becoming such a peripatetic charnel house. Is it any wonder that the average human system, being thus saturated with impurities, should succumb to the first exciting cause? Is it not, in fact, a greater marvel that the rate of mortality is not even higher than at present?
I received 10 oz. of amalgam, and having found what constituted its impurities proceeded to experiment as to its treatment. When retorted on the mine it was turned out in a black cake so impure as almost to make it impossible to smelt properly.
A main idea of Taoism one with which the Confucius of orthodox Confucianism did not concern himself is the possibility of creating within one's outer and mortal an inner and immortal self; by subduing desire, by sublimating away all impurities, by concentration. The seed of that Immortality is hidden in us; the seed of mastery of the inner and outer worlds. Faith is the key.
What was known with certainty was that the Father preached against the impurities and injustices of the age with a vehemence never heard before, and that when he spoke of the wickedness of the world toward woman, of the temptations that were laid before her temptations of dress, of luxury, of false work and false fame and then of the cruel neglect and abandonment of woman when her summer had gone and her winter had come, his lips seemed to be touched as by a live coal from the altar and his eyes to blaze as with Pentecostal fire.
A table of standard wave lengths of the impurities in the carbon poles extending to wave length 2,000 has been constructed to measure wave lengths beyond the limits of the solar spectrum.
In opposition to the received opinion that the pearl-oyster is incapable of voluntary movement, and unable of itself to quit the place to which it is originally attached , he demonstrated, not only that it possesses locomotive powers, but also that their exercise is indispensable to its oeconomy when obliged to search for food, or compelled to escape from local impurities.
"I verily believe that God will visit the earth and His church, and that He will sit as a refiner, and purify her from all impurities; but whether He will condescend to use again such imperfect instruments as we have proved, I do not know. We have bowed ourselves in the house of Rimmon. Shall we ever be fit for the service of the house of God?"
His last scientific work, published in 1800, bears the title, "The Doctrine of Phlogiston established, and that of the Composition of Water refuted." When Priestley commenced his studies, the current belief was, that atmospheric air, freed from accidental impurities, is a simple elementary substance, indestructible and unalterable, as water was supposed to be.
We open sewers for matters that offend the sight or the smell, and contaminate the air. We carefully remove impurities from what we eat and drink, filter turbid water, and fastidiously avoid drinking from a cup that may have been pressed to the lips of a friend.
