568 Reviews—Neues Jahrbuch, ete. 
excellent papers on Geology in its various branches, but more par- 
ticularly as to Petrology, Mineralogy, and Crystallography, though 
Geology proper is not wanting, and Palzontology is not without 
good representative memoirs. Unfortunately, it seems that scientific 
periodicals do not pay well anywhere; and our German brethren 
are advised by their publishers to enliven their magazines, if possible, 
and at the same time try to bring them out with the least possible 
expense, so that the publishers shall not regret having to do with 
science. After many years of hard struggling against the impecuni- 
osity of working savants, against the hard times of civil commotion, 
and against the competition of more or less scientific rival publica- 
tions, the ‘ Neues Jahrbuch ” (which commenced as the “‘ Jahrbuch,” 
etc., in 1880, and re-started as “ New” in 1838, living on with the 
lives of two eminent editors, and then surviving for some years 
under two others, and until 1879 under one of these) has been led 
to another phase by its publisher and a new company of editors. 
“In the midst of counsellors there is safety;”? and three editors, 
with a committee of several others, equally energetic and well 
prepared, hope well of the future. The new staff of professional 
geologists and mineralogists can, doubtless, supply enough material 
for the “Jahrbuch” ; but the publisher has economised his expenses 
over the periodical by less frequent issues during 1879, and proposes 
to send out only two parts or volumes for the “ Neues Jahrbuch ” of 
1880, each consisting of three numbers of fifteen sheets each. The 
price will be 20 marks a volume. Whatever the form or the price, 
we trust that geologists at large will not be losers. Publishers have 
their own views of the value and the profits of books; and we 
sincerely trust that the ‘‘Neues Jahrbuch” will be profitable to its 
proprietor in its new form, for it has always been, and we trust will 
be in the future, of very great value to geologists. The volume for 
1878, under our old friend Prof. Dr. H. B. Geinitz’s care, besides a 
great collection of letters, notices, and abstracts, as heretofore, con- 
tains the following original papers :— 
H. Hofer, on the Giant’s Chaldrons near Portschach, in Carinthia; F. Sandberger, 
on Basalt and Diorite, near Schwarzenfels in Hesse; A. Baltzer, on the Geology 
of the Swiss Alps (contact-phenomena at the north boundary of the Finstaarhorn 
central mass, two papers) ; Th. Wolf, Cotopaxi, and its Eruption of 26th June, 1877 ; 
Friedrich Scharfe, Topaz and Quartz; K. Dalmer, the Felspar-Pseudomorphs of the 
Wilhelmsleite, near Ilmenau; A. Wichmann, on the Sericite Rocks of the Taunus ; 
E. Kalkowsky, on the Granite-porphyry of Beucha, near Leipsic; A. Kenngott, on 
the Fundamental Conditions of the Crystal Species; A. Knop, on the Hydrographical 
Relations between the Danube and the Aix Springs on the Baden Highlands; J. J. 
Pohl, on a Simple and Sure Method to distinguish true Turquoise from its imitations ; 
H. Trautschold, on Methods and Theories in Geology ; H. Goeppert, on the Quanti- 
met uonoruga of Amber; Karl Zittel, on the Classification of Fossil Sponges ; 
: sasaulx, Mineralogical Work in the University of Breslau; B. Lundgren, 
on Angelin’s Geological Sketch-map of Sweden; A. Streng, on the Silver-pyrites of 
Andreasberg, and on the Ores of Charfacillo in North Chile; H. Conwentz, on the 
Tertiary Occurrence of Cypress-like wood near Calistoga in California; F. Gréger, 
on the Phenomena of Earthquakes and Volcanic Eruptions; Ad. Schmidt, the 
Quartz-diorite of Yosemite, and a variety of Hornstone. 
The first and second Nos. for 1879 (under the old management) 
contain :—
