On the following day they were inflamed and the lids nearly closed. Julius refused to eat, and experimentation was impossible. Until June 2 careful treatment and regulation of diet was necessary. He passed through what at the time seemed a rather startling condition, but rapidly regained his usual good health, and on June 3, although somewhat weak and listless, he again worked fairly steadily.
These and a multitude of other difficulties, constituting problems of the most intricate nature, impeded the progress of the telephone art, but American engineers, by persistent study, incessant experimentation, and the expenditure of immense sums of money, have overcome these difficulties.
Immediately after the voyages of Columbus and Vasco da Gama there began a tremendous religious ferment; the awakening of intellect went hand in hand with the moral uprising; the great names of Copernicus, Bruno, Kepler, and Galileo show that the mind of man was breaking the fetters that had cramped it; and for the first time experimentation was used as a check upon observation and theorization.
Careful experimentation will usually show this to be a matter of the way the thermometer is hung in relation to the heating surfaces and to the eggs. Ovi-thermometers, which consists of a thermometer enclosed in the celluloid imitation of an egg, are now in the market and are perhaps as safe as anything that can be used.
It was fed, and from that moment began to eat and sleep regularly, and made a complete recovery. "The father appeared before a legislative committee at Albany, in opposition to certain bills which were pending at the last session to restrict animal experimentation, and told this incident, and said at the close that when he saw Dr.
When Roentgen came forward with his discovery of the new "X"-ray in 1895, Edison was ready for it, and took up experimentation with it on a large scale; some of his work being recorded in an article in the Century Magazine of May, 1896, where a great deal of data may be found. Edison says with regard to this work: "When the X-ray came up, I made the first fluoroscope, using tungstate of calcium.
In some of these camps, and especially in those of the West, the refugees were finally sent out to other sections in need of labor, as in the cases of the contrabands assembled with the Union army at first at Grand Junction and later at Memphis. There were three types of these camp communities which attracted attention as places for free labor experimentation.
"It took several generations of continuous experimentation by the Sagemen to acquire the fundamental principles of telepathy and many more to establish the custom of conversing with the mind instead of the voice. In the beginning, the evil ones looked upon the practice with horror, for it was impossible to conceal anything from their fellow beings.
The common school system is constructed on the theory that children are closely similar in their abilities, type of mental make-up, and capacities in any given line. Experimentation shows each one of these presuppositions to be false. So far as general ability goes, children vary from the genius to the feeble-minded with all the grades between, even in the same school class.
For this problem, it proved impossible to establish and maintain uniform conditions of experimentation. Instead, because of the failure of the animal to improve and the tendency to discouragement, both punishment and reward had to be altered from time to time, and other and more radical changes were occasionally made in the experimental procedure.
