Nature, 1872 MR. ELLERY has been so good as to send me an enlargement of the lunar photograph taken with the great Melbourne telescope, to which you allude at p. 228, No. 142 of your Journal. This picture, Mr. Ellery tells me, was taken on the second evening of trial; it is very beautiful, although not so critically sharp as several I have obtained with my ...

Asian Journal of Organic Chemistry, EarlyView.An interrupted Barton–Zard reaction/Friedel–Crafts alkylation telescoped reaction provides aryl‐substituted pyrrolo[3,4‐b] cores in moderate‐to‐good yields as mostly single diastereomers. The reaction is tolerant of a wide range of electron‐deficient indoles and (hetero)aromatic nucleophiles, offering a modular approach for the synthesis of multi ...

The Tercentenary of the Telescope [PDF]
Nature, 1910 THE article on the tercentenary of the telescope, published in NATURE of December 16, 1909, is extremely welcome, not only because of its appositeness in point of date, but because Dr. Dreyer sets in true light the nature of Galileo's claims in connection with the discovery of the telescope.
