OF THE ATMOSPHERE THE HISTORY OF THEIR DISCOVERY BY WILLIAM RAMSAY, F.R.S. PROFESSOR OF CHEMISTRY IN UNIVERSITY COLLEGE, LONDON Reese "Modern discoveries have not been made by large collections of facts, with subsequent discussion, separation, and resulting deduction of a truth thus rendered perceptible. A few facts have suggested an hypothesis, which means a supposition, proper to explain them. The necessary results of this supposition are worked out, and then, and not till then, other facts are examined to see if their ulterior results are found in Nature."-DE MORGAN, A Budget of Paradoxes, ed. 1872, p. 55. |
