his miscellaneous papers, including those on Mastodon and Elephas. 
Unfortunately, these volumes are a mere fragment, many of Dr. 
Falconer’s determinations and discoveries, though current amongst 
geologists, having never been published in detail by their author. 
Among the reports on the Progress of Literature and Science 
in France is an important one by M. Daubrée on Experimental 
Geology, in which the author records the success which has attended 
those who have endeavoured to solve geological problems by 
imitating nature. 
M. Renevier has published, in the ninth volume of the ‘ Bulletin 
de la Société Vaudoise des Sciences Naturelles,’ the conclusion of 
his essay on the Cheville fauna. He comes to the conclusion that 
the Cheville beds contain three divisions, the upper being equivalent 
to our Lower Chalk, the middle to the “ Upper Gault ” of the Alps 
and Jura, corresponding, in the author's opinion, to our Upper Green- 
sand, and the lower to the Middle and Lower Gault of Switzerland, 
or the Gault proper of English geologists. It is satisfactory to 
find that M. Renevier’s elaborate investigation has led him to 
endorse our English classification, and to state his conviction that 
the “zone of Pecten asper,” or “ Lower Cenomanian” of French 
geologists, the Upper Greensand of England, and the Upper Gault 
of Switzerland, are but three faczes of the same formation, having 
: position intermediate between the Gault proper and the Lower 
halk. 
Professor Karl F. Peters has published an interesting memoir 
in the twenty-seventh volume of the ‘ Denkschriften’ of the Vienna 
Academy, entitled “Grundlinien zur Geographie und Geologie der 
Dobrudscha.” This district, which includes the lower basin of the 
Danube, is in many respects very remarkable. It contains repre- 
sentatives of the Bojic and Hercynian Gueiss, the Trias, the Lias, 
the Middle and Upper Jura, and the Cretaceous formation, with 
Miocene freshwater deposits, Steppe-limestone, and Loess. All these 
are described by the author, as well as many fossils from the Mus- 
chelkalk and the Middle Jura. 
“Aus dem Orient. Geologische Beobachtungen am Nil, auf der 
Sinai-Halbinsel und in Syrien,” by Dr. O. Fraas, is a very important 
book on a region but too little known to geologists. The author 
describes the crystalline rocks of the Sinai district and between 
the Red Sea and the Nile; the Cretaceous rocks of Palestine; the 
Kocene and Miocene formations of Egypt; the younger marine 
deposits, and the fluviatile formations of the Nile. There are many 
tempting subjects in this book, had we but space to recount them ; 
amongst them we must mention the author’s theory of ancient 
glaciers on Mount Sinai; the peculiar features of the “ Wadis,” and 
his theory of their formation; the description of the works on the 
Suez Canal, &c. There is one paleontological fact of great interest
