Abstract
AT the next General Assembly of the International Astronomical Union, to be held at Paris on July 10-17, the French National Committee of Astronomy is arranging an exhibition of astronomical documents and apparatus, to exhibit the principles and the details of application of the methods of observation employed. The examination of actual instruments shows better than any description how they are applied, while original negatives or positives on glass will enable the quality of the results obtained to be judged. The exhibition will enable astronomers to examine the documents serving as the foundation of the astronomical discoveries of the present century. It is particularly hoped that auxiliary apparatus and accessory contrivances of all kinds will be exhibited by observatories and instrument makers: such instruments are micrometers, chronographs, photometers, spectrographs, driving motors, observing sheds and seats, abacuses, numerical tables and calculating machines. Inquiries can be addressed to M. le Comte de la Baume Pluvinel or to Prof. C. Fabry at the Paris Observatory.
