In face of the progress made by extra rapid dry processes, the question of shutters has become the most important, since cabinet-making, optics, and photographic chemistry give us apparatus, objectives, and products which, although they will doubtless be improved upon, satisfy for the present all our needs. What is understood by instantaneousness?
One day I thought I would look up a few points regarding the relative value of foods from a scientific basis. In my chemistry I ran across a table giving the quantity of water contained in certain foods. I found that about everything I had been eating was the aqueous fluid served up in one way or another. Here is a part of the table:
A revolutionary despises everything doctrinaire, and renounces the science and knowledge of this world in order to leave it to future generations; he knows but one science: that of destruction. For that, and that only, he studies mechanics, physics, chemistry, and even medicine.
I have arranged that my nephew, John Forrester, is to come and do for me what I cannot so well manage without help; and as I have no idea of falling behind the high farming of the times, I have given him a thorough course of the agricultural chemistry, so much in fashion, before he tries the practical branch of the science.
The department of philosophy in the imperial library contained in 190 B.C. 2705 volumes by 137 authors. 'Crude, 'primitive, 'mediocre, 'vague, 'inaccurate, 'want of analysis and generalization, are terms we find applied to their knowledge of such leading sciences as geography, mathematics, chemistry, botany, and geology.
My father had been interested in chemistry and photography, it seemed, and had lately completed a new invention, the acmegraph, for taking successive photographs at measured intervals of so many seconds by electric light. He was a grave, stern man, the papers said, more feared than loved by his servants and neighbours; but nobody about was known to have a personal grudge against him.
By this solid discipline of mathematics, chemistry, and medicine, M. Taine became that which above all things he now is, a man possessed of a central philosophy, of an exact, categorical, well-defined system, which accompanies and supports him in his most distant literary excursions.
The man on the extreme right, as we face them, is Zezdon Fentes of Thought, Zezdon apparently meaning something like professor, or 'First Student of. Those next him are Zezdon Afthen of Physics and Zezdon Inthel of Chemistry." Zezdon Afthen offered them the headsets, and in a moment everyone present was wearing one.
In natural philosophy little progress was made; but a strong desire of its improvement was entertained, particularly by Virgil. Human anatomy being not yet introduced, physiology was imperfect. Chemistry, as a science, was utterly unknown.
"We have also reason to believe that not only they had peculiar remedies in their times, but also if we are to credit what has been handed down to us that the art of poisoning was much better understood," said the Major. "At all events, they had not the knowledge of chemistry which now leads to its immediate detection," replied Swinton.
