three hours after the cholera-poison had been admin-

—M. Pasteur and his collaborateurs have announced 
to the French academy that they can render all dogs 
absolutely proof against the effects of rabies by in- 
oculation, however the virus may be administered. 
— Under the heading ‘ Expeditions to the Kongo 
region,’ the Frank/fiirter zeitung states, that, accord- 
ing to information obtained from a well-informed 
source, Dr. Passavant of Basle, and Dr. Pauli of 
Brunswick, arrived, at the end of February, at 
Madeira, where they met Dr. Chavanne of Vienna. 
The three travellers were to proceed almost imme- 
diately to Africa. Passavant and Pauli, wbo are 
travelling at their own expense, proposed to pen- 
etrate the interior from the Cameroon delta on the 
coast of Guinea. Dr. Chavanne, who was to be 
joined at Madeira by Dr. Lintgraf of Detmold, is, it is 
stated, directly employed by the king of the Belgians. 
He has been commissioned to trace the route for a 
narrow-gauge railway to connect the coast with Leo- 
poldville and Stanley Pool. He intended to proceed 
directly from Madeira to Banana, and take as the 
point of departure for his expedition, ‘‘ the mouth of 
a small river situated about 5° south latitude.’? Hav- 
ing completed the survey for the railway, he is to 
proceed in a north and north-east direction, to explore 
the course of the River Uelle; the object of this ex- 
ploration being the establishment of a connection be- 
tween the Kongo andthe Nile. The country situated 
to the south of the Kongo is to be explored at the 
same time by Lieut. Wissmann, also on account of the 
king of the Belgians. Dr. Chavanne was to be joined 
at Banana by a hundred Zanzibaris; and seven hun- 
dred additional Zanzibaris. were awaiting there the 
arrival of a steamer to be sent from Europe, in order 
to transport it, under the command of Belgian and 
English engineers, above the falls of the Upper Kon- 
go, to be utilized in Dr. Chavanne’s exploration. 
— The Athenaeum of March 29 states that Cou- 
dreau, J. Roche, and C. Demont have arrived at 
Para. ‘They will devote two years to the exploration 
of the Amazon basin; paying particular attention to 
anthropology and natural history, without neglecting 
purely geographical and commercial questions. They 
travel under the auspices of the French ministry and 
marine. 
—Dr. Nathorst, of the late Swedish expedition to 
Greenland, has just issued his report on the geology 
of Waigatt Strait, near Disco Island, and on the at- 
tempt of the Sofia to reach Cape York in 1883. 
— The fourth volume of the Meddelser om Gronland 
has appeared, with important contributions to the 
knowledge of that region. Hammer contributes a 
study of Jacobshavn Fiord, made during the winter 
of 1879-80. Another chapter, on the glaciers of North 
Greenland, is the work of Steenstrup, who also re- 
ports on the deposits of nickeliferous iron ore, and 
on the geognosy and geography of a part of North 
Greenland. The book also contains researches on 
the composition of the native iron of Greenland, by

Lorenzen, and astronomical positions determined in 
North Greenland, by Steenstrup and Hammer. It is 
well illustrated, and contains a résumé, in French, of 
its contents, by Professor Johnstrup. The two suc- 
ceeding volumes are in press, and will contain a 
study of the miocene and cretaceous fossils of North 
Greenland, with an account of the explorations made 
on the east coast of that country by Messrs. Vandel, 
Normann, and Holm. 
— The royal society of Canada will hold its next 
annual session at Ottawa, May 20 and following 
days. 
— The work of the Austrian geological institute 
has been carried on, the past year, by Stache and Tel- 
ler, with the temporary co-operation of Berwerth 
and Baron Camerlander, in the central chain of the 
Tyrol and the easternmost portion of the frontier of 
Carnithia; by Mojsisovics, Bittner, and Vacek in the 
north-western part of Styria and in the revision of 
the calcareous Alps of Salzburg; by Paul and Uhlig 
in the Carpathians of Galicia; and by Tietze and 
Hilber in the other portions of Galicia. Von Hauer 
and Mojsisovics also examined the thermal springs 
in Baden (south of Vienna), whose temporary inter- 
mittence had caused grave apprehensions; and Moj- 
sisovics visited Bosnia, Istria, and Trifail, in Styria, 
with reference to coal-deposits. Stur studied the coal- 
formation of Taworzny in Galicia, where the mines 
had been much damaged by the irruption of water. 
Paul examined several petroleum districts in Galicia 
and North Hungary, and searched for coal and salt 
deposits in the neighborhood of Tuzla in Bosnia, 
where a boring, executed under his direction, met, at 
a depth of ninety metres, water saline enough to be 
used for industrial purposes. Bohm investigated 
the glacial phenomena in the valley of the Enns. 
Frauscher studied the eocene faunas of the northern 
Alps of Upper Austria; Geyer, the todtegebirge of 
Upper Styria; and Tausch, the cretaceous deposits of 
Ajka. The library now contains about twenty-nine 
thousand volumes. 
— The commission for the geological survey of Bo- 
hemia reports, that, during the past year, Krejci and 
Feistmantel studied the still imperfectly known west- 
ern Silurian deposits, which are interrupted by great 
faults, pafallel to the strike of the whole system, and 
causing a great number and diversity of synclinal 
and anticlinal foldings; Fritsch surveyed the Teplitz 
strata, near Podiebrad and Chrudim, and Kafka the 
Chlomek strata in Glatz; Laube continued his inves- 
tigations in the metalliferous region of Kaaden and 
Komotau; the passage of the railway through this 
region proved that the anthracite zone of the Saxon 
Erzgebirge continues along the borders of the por- 
phyritic region, at a distance of about five kilometres 
from the Saxon frontier. As is usually the case in 
the metalliferous regions of Bohemia, no traces of 
glacial action could be discovered. 
—Mr. J. F. Whiteaves, paleontologist to the Do-

of the survey, on the fossils of the coal-bearing beds
