Nancy, P. Savy, 1883. 8vo (22.9 x 15.7 cm). Typed title page; 336 pp., four handcoloured folded profiles, one folded coloured geological map. Later half cloth over marbled boards. Typed label on the spine. = A detailed study on mostly Mesozoic strata. The author, [Jean Vincent] Jules Wohlgemuth (1854-1893) was a French geologist and mineralogist. The map shows the area around and west of Metz and Nancy, in eastern France. Offprint from the Bulletin de la Société des Sciences de Nancy, série II, tome IV fascicule XV. The offprint probably did not have a separate title page, so a former owner added a neatly typed one. Some light, scattered, marginal spotting to the text. Otherwise a very good and clean copy. Rare.
