"This result was unexpected, but it was far from convincing me that the substances which were obtained were generated. In a similar process with glass tubes, carried on under exactly the same circumstances and for the same time, I obtained a quantity of alkali which must have been more than twenty times greater, but no traces of muriatic acid.
From his numerous experiments upon the air, Boyle was led to believe that there were many "latent qualities" due to substances contained in it that science had as yet been unable to fathom, believing that there is "not a more heterogeneous body in the world."
Experiments have been made for the purpose of estimating these additions, and the results of those most carefully conducted show how very slightly the combined causes affect the general composition of our atmosphere; and although the present refined methods of chemists enable them to detect the presence of an abnormal amount of some substances, no research has yet been successful in determining how far this varies from the natural quantity at all times necessarily present in the atmosphere.
Ugliness, nay, repulsiveness, vanish, subdued into beauty, even as noxious gases may be subdued into health-giving substances by some cunning chemist.
When, therefore, an eminent electrician like Professor Fleming says, "We have overwhelming proof that in the manufacture of the infinite number of substances made in Nature's laboratory there must be at all stages some directivity," this can only mean that Professor Fleming cannot see the way in which these substances are made. It does not mean that he sees how they are made.
The piece of ancient asbestos cloth preserved in the Vatican was formed, we believe, by mixing the asbestos with other fibrous substances; but M. Aldini has executed a piece of nearly the same size, 9 feet 5 inches long, and 5 feet 3 inches wide, which is much stronger than the ancient piece, and possesses superior qualities, in consequence of having been woven without the introduction of any foreign substance.
Or, an explosive may be a mere mechanical mixture of different substances comprising the necessary elements, as is ordinary black gunpowder, which is a compound of charcoal, sulphur and saltpeter, the saltpeter supplying the necessary oxygen.
It has been applied to substances in which there is no lime; as, to that red loam usually called red marl in certain parts of England. Agriculturists were in the habit of calling any soil a marl which, like true marl, fell to pieces readily on exposure to the air.
Over the footprint at the north of the city the king built a large tope, four hundred cubits high, grandly adorned with gold and silver, and finished with a combination of all the precious substances. By the side of the tope he further built a monastery, called the Abhayagiri, where there are now five thousand monks.
I practise political virtue: it embarrasses the world, it fogs them, it seems original, because so unnecessary. Mine is the scientific life. Experiment in old substances gives new well, say, new precipitations. But you are scientific, too. You have a laboratory, and have much to do with retorts." "No, you are thinking of my husband. The laboratory is his." "But the retorts are yours."
