THE GEOLOGICAL TOURIST IN EUROPE. 229 



(17) Filhrer fur Besuclier des Nahethal, 1884, Voigtlander, Kreuznach, has 

 geologic and botanic appendices. 



The work of the Prussian Survey of Weiss and Laspeyres, and the Flotzkarte 

 of Saarbrilcken may be noticed. 



(18*) Ludwig, R., published a Geologische Skizze, to go with the map of 

 Hesse (see 3), out of print now. There is a new survey by Lepsius in course of 

 publication. 



(19*) Geognostische Beschreibung der Umgebung von Heidelberg, Benecke 

 & Cohen, 1877. 



(20*) Eck, H., has issued a series of good maps on the Black Forest, the Black 

 Forest Railway and environs, Renchbader, Ottenhofer, etc., very much detailed, 

 poorly printed, and cheap in price; 1885-'87, Lahr. 



(21) Heim, A., is the great authority on the structure of the Alps, folds, 

 faults, etc. His results are given, however, in (6), (8), and especially (10). Tyn- 

 dall and Agassiz are mentioned, honoris causd, on glaciers. 



(22*) Stapf, Geological Map of the Saint Gothard Railroad from Erstfeld to 

 Arbedo, 1:25,000. Practically covers the whole crystalline belt. 



(23) Italy has been traversed by so many that the geological literature is 

 wide-strewn. A bibliography was published in 1881 for the International Geo- 

 logical Congress at Bologna. J. Roth's Vesuv. and Lavis, in the " Quarterly Jour- 

 nal of the Geological Society," London, are up to date. 



(24*) Lotti, B., Desc. Geol. del Isola Elba, 1886. 



(25) Carta Geol. della Campagna Romana, 1880, Roma. 



For the Tyrol the Italian part of the Austrian publications should be noted. 

 Guides to collections often have a wider usefulness. Among such pre-eminent 

 are those for Berlin and Strasburg. 



(26*) For Wtirtemberg, besides the old Geognostische Verhaltnisse, by Hehl 

 (1 mark), 1850, Schweizerbart, Stuttgart, is the newer — 



(27) Die geognostische Sammlungen Wtlrtembergs, by Oscar Fraas (0'50 

 mark), third edition just out, Schweizerbart. Stuttgart. 



(28) Laube, G., Geologische Excurs. im Thermalgebirte desN.W. Bohmens, 

 1884, Leipsic. Among other workers in the same field in journals are Reuss, 

 Boricky, Becke, and Patton. 



(29*) Oredner, H., Geologischer Fuhrer durch das sachsische Granulitge- 

 birge, 1880, W. Engelmann, Leipsic. There is also a fuller "Beschreibung" by 

 the same author. 



(80*) Lossen, K. A., has published a very thorough map of the Harz, which 

 is expensive. The literature is mostly published by the Prussian Survey. See 

 (3), as also for Bavaria. 



(31) Meunier, S., Excursions g^ologiques a travers la France, 1882, G. Masson, 

 Paris. (Chatty; includes Belgium and part of Switzerland.) 



The smaller French school-books, e. g. — 



(32*) Von Raulin, Elements de G6ologie, are very local, and handy to the 

 pocket. 



(33) Catalogues to porcelain manufacture, to geologic models, to rock speci- 

 mens, fossils, mineral collections, mining records, and guide to geology of Lon- 

 don (prices 3s., 2s. 6d., 2s., 2s., 4s. 6d., and Is.), Museum of Practical Geology, 

 Jermyn Street. 



(34) Scientific Guide to Switzerland, Morrell. I have not tested it by ex- 

 perience. 



(35) Hibsch gives the literature of northwestern Bohemia in Tschermak's 

 Min, and petr., Mittheilungen, 1887, Wien, Alfred Holden.
