and high pressures, and also to the critical phenomena and 
constants of oxygen. 
At the present time the electrical installations of the 
laboratory are being largely increased. There are already 
three dynamos which can give a current of 200 amperes at 
120 volts, and two motors will be ready shortly to drive 
scme of the pumps and other apparatus. 
The possibility of making and fitting the highly specialised 
and intricate apparatus required for some of these measure- 
ments is largely aided by the circumstance that the labor- 
atory is combined with a technical school for instrument 
making and certain branches of electrical technology. 
About twenty apprentices are at present passing through 
the wood, metal, and glass workshops, each of which is 
controlled by a skilled workman. In this way the con- 
struction and repair of apparatus, and the help required 
for complicated experiments, can be obtained in a most satis- 
factory manner. This unique combination of research 
laboratory and technical school is well worth a visit from 
physicists touring in Holland, who will receive a friendly 
welcome from Prof. Onnes. H. H. F. Hynpman. 
No. 6; 
AUSTRIAN GEOLOGICAL SURVEY. 
SOME important publications of the Austrian Geological 
Survey have reached us, namely, the first part of the 
twentieth volume of the Abhandlungen der k.k. Geo- 
logischen Reichsanstalt, Vienna (1903), the second, third 
and fourth parts of the fifty-second volume and the first 
part of the fifty-third volume of the Jahrbuch (1902-1903). 
The first of these works is a valuable memoir by Ernst 
Kittl, on the Cephalopoda of the Upper Werfen beds of Mué, 
in Dalmatia, and other localities, and comprises seventy- 
seven pages and eleven plates. As indicated by the title, the 
greater part of the material described in this memoir was 
obtained from the locality discovered in 1862 at Mué (or 
NO. 1785, VOL. 69] 
Much), in northern Dalmatia, but some of the specimens 
are from other areas, including certain Alpine localities. 
Some account is given of the various places where similar 
strata have been met with, and numerous references are 
made to the writings of other workers. The description 
of the various genera and species constitutes the bulk of 
the work. All the forms noticed are included in two 
families :—(1) the Ceratitidee, with the genera Dinarites, 
Stacheites, Ceratites, and Tirolites; and (2) the family 
Pinacoceratidz, with the genera Kymatites, Meekoceras, 
and Dalmatites. Of these genera Stacheites alone is new 
to science, but certain subgenera and thirty-four species are 
described and named for the first time. 
In conclusion, the author directs special attention to the 
importance of the few precursors of the Muschelkalk 
Cephalopoda, such as Dalmatites, Ceratites, and some nearly 
allied forms, which are now for the first time known to 
occur in the Werfen beds. 
A comparison with the Permian and Carboniferous fauna 
of Silesia, Russia, and India shows the comparative poverty 
of the Werfen beds, and the author points out that the 
scanty fauna goes ‘‘ hand in hand ”’ with the small amount 
of calcareous matter in the deposit. 
The second part of the Jahrbuch indicated above contains 
several interesting papers on various subjects, each being 
illustrated by plates or text figures. Dr. Karl Hinterlechner 
describes the petrographical characters of some rocks from 
the Cambrians of western Bohemia. The ‘‘ Erzberg ’’ in 
Hittenberg, Carinthia, is described by Bruno Baumgartel ; 
Dr. Rudolf Zuber gives us some new studies in the 
Carpathians; while Hermann Bock supplies an account of 
the physical structure of the neighbourhood of Briinn. 
Then follow three paleontological papers :—Rich. Joh. 
Schubert, on some bivalves from the Istro-Dalmatian 
“* Rudistenkalkes ’’; Vincenz Hilber, on some fossils from 
the Gosau beds of Kainach and Séding, in the northern 
parts of Voitsberg—in this paper one new species is de- 
scribed under the name of Hippurites Styriacus ; Adalbert 
Liebus and Rich. Joh. Schubert describe the Foraminifera 
from the Carpathian Inoceramus beds of Gbellan, in 
Hungary, seven new species-and four new varieties being 
named. The concluding paper, and certainly not the least 
iniportant, is by Dr. H. Graf Keyserling, and is entitled 
‘““ Geologico-petrographical Studies in the Region of the 
Melaphyre and Augiteporphyry of the Southern Tyrol.” 
This is a detailed communication of some forty pages, 
which will doubtless be carefully studied by all interested in 
this particular subject. 
The third part is devoted to a detailed account of the 
localities and horizons yielding useful minerals in the so- 
callea Archaic and Devonian island of Westmahren, by 
Franz Kretschmer, mining engineer at Steinberg. This 
memoir of 142 pages deals very fully with the geological 
and physical conditions under which the graphite, lead, iron 
ores, &c., are found, and it is illustrated by a geologically 
coloured map, with sections and plans. 
The fourth part of this volume is a memoir by A. Bettner 
on the Brachiopoda and Lamellibranchiata from the Trias 
of Bosnia, Dalmatia, and Venetia, occupying 149 pages, and 
illustrated by ten lithographic plates and seventeen zinco- 
graphs in the text. The greater part of this work deals 
with fossils of Middle Trias or Muschelkalk age, derived 
from several localities, but perhaps a greater interest will 
be attached to the last twenty pages, dealing with the Upper 
Trias or Keuper forms from two localities in Bosnia. The 
whole memoir is a detailed description of species, and, as 
might be expected from their age and the little known 
localities from which they are derived, many of them prove 
to be new, but one cannot but be surprised to find that of 
seme two hundred forms here described one hundred require 
new names. ‘The plates accompanying this work are clearly 
drawn, but it is to be regretted that the figures are so 
crowded. All who have worked with such plates know how 
troublesome this is; one’s eyes become dazed when trying 
to concentrate upon any particular figure. No doubt this 
memoir, like the one above noticed on the Werfen Cephalo- 
poda, will become a classic in Triassic literature. 
Part i. of vol. liii. contains several papers; the first of 
these, by R. Hoernes, on the ontogeny and phylogeny of
