4i6 Notes and Comments. 



feature is the excellence of the numerous illustrations. The 

 articles also are such as will appeal to all lovers of nature. 

 Besides dealing with various aspects of country homes, there are 

 articles on old sun-dials, windmills, old-fashioned industries, 

 duck-decoys, beech trees, natural history of the garden, pre- 

 historic implements, old fire-places, snails, megaliths, etc., etc. 

 Amongst the names of the contributors, we notice a well- 

 known worker, IMr. Wilfred ]\Iark Webb. 



THE MINERAL KINGDOM. 



This well-known work, by Dr. Bernard Brauns, Professor 

 of Mineralogy in the University of Bonn, is appearing in twenty- 

 five parts, at two shillings each. It is being published by Messrs. 

 Williams and Norgate, and has been translated, with additions, 

 by Mr. L. J. Spencer, M.A., F.G.S., of the British Museum. 

 The specimens before us each contain twenty pages of letterpress, 

 and two excellently-coloured plates ; in fact, the difficulty of 

 adequately representing the metallic colours and beautiful tints 

 of many minerals, seems almost to have been overcome. When 

 complete, the work will contain ninety-one plates, seventy-three 

 being coloured, and two hundred and seventy-five illustrations 

 in the text. Though originally published in Germany, ' The 

 Mineral Kindgom ' contains many references to British speci- 

 mens. English students will find the publication of great 

 value to them, particularly as it is obtainable in instalments. 



EUROPEAN GLACIAL DEPOSITS. 



Some little time ago Mr. Frank Leverett, of the United 

 States Geological Survey, paid a visit to Europe for the purpose 

 of investigating the glacial deposits of that continent. Mr. 

 Leverett 's excellent work among the more recent deposits of 

 North America, makes a perusal of his report of peculiar 

 interest to English glacialists. It has been issued and printed 

 in Berlin in Vol. IV. of the Zeitschrift flir Gletscherkunde,' 

 though we are thankful to say it is printed in English. The 

 report, which is entitled ' Comparison of North American and 

 European Glacial Deposits,' is an extensive one, and is accom- 

 panied by a valuable series of maps of Great Britain, the Alps, 

 North Germany, North America, etc., showing the glacial 

 features of these areas. Mr. Leverett 's remarks on the young 

 Morainal Drift of England are of so much interest that we take 

 the liberty of giving them in full.
