Abstract
NOTHING could have been further from my intention than to do any injustice to Dr. Steinheil or his firm, and I hasten to acknowledge the justice of his criticisms upon the slips contained in my edition of Lummer's book—slips for which I take the entire responsibility. The error on p. 100 in supposing that the Munich view was photographed by Prof. Miethe, of Berlin, arose from a confusion between two sets of telephotographic views sent me from Germany, some of which were taken by Prof. Miethe. I would point out that, in the only case in which the kind of lens used is stated, it is correctly stated to be a Steinheil's lens. I presume Dr. Steinheil is not dissatisfied with the performance of the lens in producing the picture, by whomsoever it was photographed. The other point arose from inserting at the last moment, when the sheets were going to press, a reference to Messrs. R. and J. Beck, which should have been inserted at the end of paragraph four instead of paragraph three of Chapter xi. Let me assure Dr. Steinheil that both points will be corrected in any fresh issue of the text.
