For more isolated houses the cooling and ventilating apparatus of the future may be a modification of the "shower-blast" which has been successfully adapted to metallurgical purposes.
He had a considerable gift of speech, as the College Debating Society, which met amidst the crushing machines and mine models in the metallurgical theatre downstairs, already recognised recognised by a violent battering of desks whenever he rose.
But it will be appropriate before passing on to note that on January 17, 1908, while this biography was being written, Mr. Edison became the fourth recipient of the John Fritz gold medal for achievement in industrial progress. This medal was founded in 1902 by the professional friends and associates of the veteran American ironmaster and metallurgical inventor, in honor of his eightieth birthday.
The most intelligent engineers, after ascertaining by exhaustive physical tests what they need, present their "requirements" to the iron and steel makers, whose practical experience and science guide them in the protracted metallurgical experiments necessary to find the exact process required.
There are drawing, photographic, and photometric chambers, physical, chemical, and metallurgical laboratories. There is a fine lecture-hall, and a splendid library and reading-room. He employs several hundred workmen and assistants, all chosen for their intelligence and skill. In this retreat Edison is surrounded with everything that his heart desires.
The Francke "tina" process is based on the same metallurgical principles as the system described by Alonzo Barba in 1640, and also on those introduced into the States in more recent times under the name of the Washoe process.
Upon the future of these works will probably depend for many years to come the success of the metallurgical and other kindred industries of India, and it is to be hoped that Government will be allowed to give them all reasonable assistance without interference from home. Another purely Indian enterprise also under the auspices of Messrs.
The application of electricity to metallurgical and chemical work has been, in nearly all cases, the result of scientific research, and elaborate experimental laboratories are maintained by the various corporations interested in the present or future use of electrical processes.
They also enable us to learn the different metallurgical processes, the different alloys, the modes of gilding and plating practiced by the ancients, the metals which they used, their weight and measures, their different modes of reckoning, the names and titles of the various kings and magistrates, and also their portraits, their different divinities, with their attributes and titles, the utensils and ceremonies of their worship, the costume of their priests in fine, everything which relates to their usages, civil, military, and religious.
After many years of tedious working devoted to experiments bearing on the metallurgical treatment of rich but refractory silver ores, the inventor has successfully introduced the process of which it is proposed in this paper to give a description, and which has, by its satisfactory working, entirely eclipsed all other plans hitherto tried in Bolivia, Peru, and Chili.
