^{page 40 note 1} The paper by Prof. Nordenskiold especially referred to by Prof. Judd, is “On the Former Climate of the Polar Regions,” being an address by Prof. Nordenskiold delivered at the Anniversary Meeting of the Royal Swedish Academy of Sciences, March 31, 1875, and translated and printed in full in the Geological Magazine, 1875, Dec. II. Vol. II. p. 525. The passage quoted by Prof. Judd appears at p. 531, but the whole paper is well worthy of perusal; as is also his paper “On the Geology of Icefiord and Bell Sound, Spitzbergen,” GEOLOGICAL1 MAGAZINE for 1876, pp. 16, 63, 118, 255. Perhaps Prof. Green will “get a kind friend to read them for him.” Nordenskiold’s “Expedition to Greenland” also appeared in the Geological Magazine., 1872, Vol. IX. pp. 289, 355, 409, 449, 516, and has some good materials in it bearing on the former climate and the extinct floras. Many of our readers, when oppressed with the wearisome effort to master the contents of our monthly issue, will cordially sympathize with Prof. Green, and wish for a mental digester and Assimilator (like the Artificial Stomach in the Loan Collection) into which, as into a “Papin’s Digester,” they might put their heavy reading, and so get therefrom the eztractum sensorum in a concentrated form. Till this invention is patented. Prof. Green has hit upon a happy expedient: “Get a kind friend to tell you what it is about”!—Edit. Geol. Mag.
