PALEONTOLOGY. 365 



marises all that was previously known about stratigraphy and 

 palaeontology. The most important fossil types of all the geo- 

 logical formations are shown on the forty-seven folio plates, 

 and the text gives careful descriptions of the fossils and their 

 occurrence. 



The Lethcza Geognostica was followed in 1848-49 by an 

 Index Palceontologica, in which Bronn was assisted by Goeppert 

 and H. von Meyer. Both these works exerted a great 

 influence on the development of palaeontology, and were for 

 several decades the chief books of reference for all the more 

 comprehensive palaeontological works. Several other large 

 works were published in the early part of the nineteenth cen- 

 tury; among others, the Mineral Conchology of Great Britain, 

 by the Sowerbys, between 1812 and 1845 (ante, p. 131); 

 the splendid series of plates, Petrefacta Germanics, by 

 Goldfuss 1 and Count Miinster ; the Pal'eontologie Fran$aise, 

 by Alcide d'Orbigny (1840-55). Goldfuss and Miinster 2 

 intended to produce an illustrative work of all the 

 invertebrate fossils occurring in Germany, but apparently 

 found the scheme too extensive, and concluded the work after 

 the sponges, corals, crinoids, echinids, and a part of the fossil 

 mollusca had been accomplished. D'Orbigny also gave up 

 his similar scheme of an exhaustive illustrated account of all 

 the fossil Invertebrates in France; he brought to completion 

 monographs of the Jurassic and Cretaceous Cephalopods, 

 Gastropods, the Cretaceous Lamellibranchs, Brachiopods, and 

 Bryozoa, and certain groups of the Cretaceous Echinids. 



In the first volume of the Elementary Course of Palaeontology 

 and Stratigraphical Geology (1849), D'Orbigny gave a short 

 systematic summary of fossil organisms. The Prodrome of 

 Palaeontology is a list of the fossil Mollusca, Sponges, and 

 Foraminifera arranged according to the geological epochs, but 

 the list is much less complete than Bronn's Palceontological 

 Index. 



1 Georg August Goldfuss, born 1782 at Thurnau, near Bayreuth ; 

 studied in Erlangen, graduated there in 1804, in 1818 was made Professor 

 of Zoology in Erlangen, but was soon after called to Bonn University as 

 Professor of Zoology and Mineralogy; died 1848, in Bonn. 



' 2 Count George Miinster, born 1776 of a Hanoverian family, held office 

 as a Bavarian Chamberlain, and lived in Bayreuth, where he died in 1844. 

 His famous collection of fossils was procured by the Bavarian State and 

 removed to Munich, where it formed the nucleus of the present Pabeonto- 

 logical Museum.
