She smiled and blushed, and presently acknowledged, that, when she had first pulled the trigger experimentally, six months before, she had shut her eyes and screamed, although there was only a percussion-cap to explode.
Considerable discussion took place on the subject; and Sir William Fairbairn, who was President of the Section, said that "he would have experiments made, and he hoped that before the next meeting of the Association, the matter would be proved experimentally. A brief report of the discussion is given in the Times of the 7th October, and in the Athenaeum of the 18th October, 1862.
"Material bodies are all that we have any control over, are all that we are experimentally aware of; anything that we can do with these is open to us; any conclusions we can draw about them may be legitimate and true. Allow us anyhow to make the attempt. Give us a fair field.
While such great names were occupied in discussing this question, physical inquirers of a less ambitious stamp laid experimentally the solid basis of a future mathematical theory of heat. Some established, that the same quantity of caloric does not elevate by the same number of degrees equal weights of different substances, and thereby introduced into the science the important notion of capacity.
As I have elsewhere confessed, I have myself been responsible for ridiculous incantations with burning sulphur, experimentally proved to be quite useless, because poor people are convinced, by the mystical air of the burning and the horrible smell, that it exorcises the demons of smallpox and scarlet fever and makes it safe for them to return to their houses.
He gave figures from which it was easy, as Professor Van t'Hoff found, to draw the conclusion that, in a constant volume, the osmotic pressure is proportional to the absolute temperature. De Vries, moreover, by his remarks on living cells, extended the results which Pfeffer had applied to one case only that is, to the one that he had been able to examine experimentally.
All scientists without exception are agreed that the central nervous system is the organ of psychic life in the animal, and it is possible to prove this experimentally at any moment. When we partially or wholly destroy the central nervous system, we extinguish in the same proportion, partially or wholly, the "soul" or psychic activity of the animal.
As it is proved that such electro-magnetic waves have all the characteristics of light, it follows that they must originate with electro-magnetic action, that is, in the changing magnetism of a magnetic body. This makes it needful to assume that the atoms which originate waves are magnets, as they are experimentally found to be.
There are not many readers abroad like Dr. John Owen and Dr. Thomas Chalmers. In its style William Guthrie's one little book is clear, spare, crisp, and curt. Indeed, in some places it is almost too spare and too curt in its bald simplicity. True students will not be deterred from it when I say that it is scientifically and experimentally exact in its treatment of the things of the soul.
Mendelism, since 1900, has studied experimentally the transmission of definite characters, and maintains that the characters of species are of the same nature as the characters which segregate in Mendelian experiments. Such characters are not in any way related to external conditions, and cannot, therefore, be adaptive except by accident.
