...lecture announced to take place in the Union next Tuesday evening by Mr. Joseph Mitchell Chapple, editor of the National Magazine, has been cancelled owing to the forced absence of Mr. Chapple. In his place Judge. William S. Bennet of the New York Municipal Court is expected to speak on "The Recent Political Campaign in New York." The lecture will be given in the Living Room at 8 o'clock and will be open only to members...
...Mr. Merrill concluded his lecture by quoting at length from a pamphlet by Hiram Maxim, the well-known authority on military aeronautics. Mr. Maxim's opinion is that the development of aerial navigation will lesson the chances of war in that nothing save subterraneous works will be free from the bombs dropped by aeroplanes...
...first of a series of lectures to be given this winter under the auspices of the newly organized Harvard Aeronautical Society was delivered last evening in the Fogg Lecture Room by Mr. A. A. Merrill, lecturer on aeronautics for the Boston Y. M. C. A. His topic was "The Principles of Mechanical Flight" and the lecture was illustrated with excellent views of the Wright, Curtiss and Bleriot machines...
...Mr. Merrill began his lecture with a brief history of the development of the aeroplane, which is the only practical method of the three employed to elevate a heavier-than-air machine. The other two the use of vertical screws and the oscillation of wings, involve almost insoluble questions of stability. No progress was made in aeroplanes until Langley showed that the estimation of power necessary to lift a given weight was erroneous. Maxim took up the Work of Langley and contrived to lift 8,000 pounds by the proper balancing of horizontal planes. Lielienthal, a German scientist, attacked...
After demonstrating the principles of soaring, by blackboard diagrams, Mr. Merrill went on to explain the present weakness of the aeroplane, namely, the engine. It is the inefficiency of the motive power which has and still does limit the range and speed of the heavier-than-air machine. It is on the engine that French scientists are now putting their greatest efforts. To get the maximum horse-power with a minimum weight is the present problem of aeronautics. If the engine ceases to supply power the aeroplane has to descend and if this happens over a country devoid of suitable...
