Abstract
LORD RAYLEIGH, in his letter (August 24), raises the interesting question of the adaptability of the plate to the object-glass. This is a novel idea, and I hope with him that we shall have the opinion of Captain Abney or some other authority on the question, or that it will be settled experimentally whether the use of an object-glass corrected for visual work will give, with properly prepared plates, results approximating those obtained with the photographic object-glass. In the case of Cambridge Observatory, there is already an object-glass of nearly twice the area of the proposed photographic telescope, so that it is quite possible as good results might be obtained with the Newall telescope as with the proposed one.
