ance, the Keuper and Bunter being very unfossiliferous. But the 
Muschelkalk even is poor when compared with deposits of the same 
age in the Alps. This is especially true of the deep-sea Cephalopoda, 
which in the German Trias are known by a few small species, but 
in the Alpine Trias by a whole series of rich faunas. The wide- 
spread Alpine Trias is the pelagic facies of the formation; the 
more restricted German Trias, on the other hand, is a shallow shore, 
bay, or inland sea formation. The fossils of this division are illus- 
trated by about seventy woodcuts, and comparative tables of the 
German and Alpine Trias in various areas are given. 
Forty-four pages are devoted to the Jurassic System and seventy 
figures to the illustration of its fossils. 
Tables are also furnished of the Liassic and Oolite strata and their 
equivalents abroad. 
Forty-six pages contain the Cretaceous system, illustrated by 
ninety figures, whilst seventy-three pages, and one hundred and 
twenty figures are devoted to the Tertiary Age. 
Making due allowance for the difficulties of bringing out such a 
work, the author and translator may both be congratulated on the 
satisfactory appearance of the English Edition. 
The figures are mostly needlessly large, which is a misfortune, 
causing them to take up too much space; the Mammoth and 
Trish Deer should be condemned as bad, and we should like to see 
more regard paid to the relative proportions of the figures of natural 
objects used in such works as the present. 
Prof. Prestwich, in his admirable Manual of Geology (1888), has 
set an example in the matter of illustrations which other writers on 
paleontology might do well to follow. 
For a small handy volume, we must commend Mr. Lake’s trans- 
lation of Dr. Kayser’s Geology as worthy of a place in any library, 
forming a useful and trustworthy guide-book to the student. The 
facts are clearly and carefully given, there is a good index, and the 
price of the volume is conveniently small.

\HE name of Howorth has long been familiar to the readers of © 
the GmoLocicaL MaGazing, as a constant contributor since 1880, 
on “The Mammoth in Siberia,” “The Mammoth in Europe,” “On 
the Loess,” ‘‘ Traces of a great Post-Glacial Flood,” “The Mammoth 
and the Glacial Drift,” etc. Many of the chapters of his first great 
book, ‘The Mammoth and the Flood,” which some of his friends 
playfully called a“ Monster Book,” appeared in the monthly numbers 
of this Macazinu, as have also portions of this his newest publication. 
“One of the chief objects,” says Sir Henry Howorth, “of this 
book, is to show that the Glacial theory, as usually taught, is not: 
sound; but that it ignores, and is at issue with, the laws which
