Nevertheless, darkness is not absolutely essential. Maxwell secured many convincing movements in the light, and no doubt we shall be able to do so later." "Who is Maxwell?" asked Miss Brush. "Dr. Joseph Maxwell, Deputy Attorney-General of the Court of Appeals at Bordeaux and Doctor of Medicine. He is a noted experimenter with psychic forces. Indeed, he has the power himself. Now, Mrs.
Everybody believes that Cavor was a not very brilliant scientific experimenter who blew up his house and himself at Lympne, and they explain the bang that followed my arrival at Littlestone by a reference to the experiments with explosives that are going on continually at the government establishment of Lydd, two miles away.
Hence the conclusion, that our analysis must dissect the complicated phenomena of evolution so far as to show the separate functions of these two contrasting principles. Hundreds of steps were needed to evolve the family of the orchids, but the experimenter must take the single steps for the object of his inquiry.
In trials of this kind the experimenter arrives at the startling conclusion that, to pass ordinary luminous discharges through gases, no particular degree of exhaustion is needed, but that the gas may be at ordinary or even greater pressure. To accomplish this, a very high frequency is essential; a high potential is likewise required, but this is a merely incidental necessity.
Its interest for us is connected with the greatest name, after Hippocrates, in Greek medicine, that of Galen, born at Pergamon A. D. 130, in whom was united as never before and indeed one may say, never since the treble combination of observer, experimenter and philosopher.
The objection to this experiment is not that it seems too funny to be taken seriously, and is not cruel enough to overawe the mob, but simply that it is impossible because the human experimenter cannot get at the mouse's mind. And that is what is wrong with all the barren cruelties of the laboratories. Darwin's followers did not think of this.
If for a particular observation the experimenter wishes to present the first three keys at the left end of the keyboard, he pushes back the remaining nine keys so that they cannot be operated and requires the subject to select from the group of three keys the one which on being pressed causes a signal to appear.
It is amusing to read the dicta which appear in the agricultural press from those who have made but a single experiment with some vegetable; they proclaim more after a single trial than a cautious experimenter would dare to declare after years spent in careful observation.
"Excuse me," said the collector, "but have you such a thing as a needle about you a very long needle?" "I have a needle book," replied Jane, politely, "but there aren't any needles in it now. George took them all to do the things with pieces of cork in the 'Boy's Own Scientific Experimenter' and 'The Young Mechanic. He did not do the things, but he did for the needles."
These sounds of whispering, inaudible under ordinary conditions, are so magnified by the two reflectors as to be distinctly heard by the second experimenter. Curtis proved that actual movements of the larynx unconsciously accompany intense thought. His demonstrations were conducted along lines familiar to all students of experimental psychology.
