(17) Führer für Besucher des Nahethal, 1884, Voigtländer, Kreuznach, has geologic and botanic appendices.
The work of the Prussian Survey of Weiss and Laspeyres, and the Flötzkarte of Saarbrücken 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, Renchbäder, 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). Tyndall and Agassiz are mentioned, honoris causâ, 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 Geological Congress at Bologna. J. Roth's Vesuv. and Lavis, in the "Quarterly Journal 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 Würtemberg, besides the old Geognostische Verhältnisse, by Hehl (1 mark), 1850, Schweizerbart, Stuttgart, is the newer—
(27) Die geognostische Sammlungen Würtembergs, by Oscar Fraas (0·50 mark), third edition just out, Schweizerbart. Stuttgart.

(29*) Credner, H., Geologischer Führer durch das sächsische Granulitgebirge, 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 géologiques 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, Éléments de Géologie, are very local, and handy to the pocket.
(33) Catalogues to porcelain manufacture, to geologic models, to rock specimens, fossils, mineral collections, mining records, and guide to geology of London (prices 3s., 2s. 6d., 2s., 2s., 4s. 6d., and 1s.), Museum of Practical Geology, Jermyn Street.
(34) Scientific Guide to Switzerland, Morrell. I have not tested it by experience.
