From a diplomatic correspondence between the representatives of Austria and Turkey, in regard to the liberation of Kossuth and his companions, it is very evident that Austria feels very keenly the discomfiture she has sustained, and that she will be very likely to resent this disregard of her wishes, by seeking cause of war with Turkey. She is stirring up rebellion in the Bosnian provinces, and concentrating her troops upon that frontier, to take advantage of any contingency that may arise. The authorities in Hungary have been absurd enough to evince the spleen of the Austrians in hanging effigies of Kossuth and his associates, condemned for treason _in contumace_. In Portugal vigorous preparations were being made for elections, in which it was expected that Saldanha's friends would generally be defeated. At the Cape de Verde Islands a terrible disease, described as a black plague, was very fatal. The differences between the governments of Turkey and Egypt are still unsettled, and the fate of the Egyptian railroad therefore remains doubtful. Scientific Discoveries and Proceedings of Learned Societies. Some recently received numbers of the _Nordische Biene_ contain interesting information concerning the organization and labors of the Russian Geographical Society. This body, like the Geographical and Statistical Society organized a few weeks since in New-York, is modelled upon the general plan of the Royal Geographical Society in London. It is, however, far from being so universal in its aims; in fact, its members confine their investigations to the Russian empire, and to tribes and countries contiguous therewith. The annual meeting is held on April 5th. At the last, two prizes were given; one of these was a gold medal offered by Prince Constantine, the other a money prize for the best statistical work. The medal was awarded to Lieutenant-Colonel Buckhardt Lemm, for a series of astronomical observations, determining the latitude and longitude of some four hundred places in Russia and the neighboring regions in Asia, as far as Mesched in Persia. These determinations are of particular value for the geography of inner Asia. The statistical prize was awarded to a Mr. Woronoff for a historical and statistical survey of the educational establishments in the district of St. Petersburg from 1715 to 1828. It is in fact a history of the development of mental culture in that most important part of the empire. The annual report, giving a survey of the Society's doings, was interesting. A special object of attention is the publication of maps of the separate governments or provinces. The Society had also caused an expedition to be sent to the Ural, under Colonel Hoffmann. The triangulation of the country about Mount Ararat had been completed. A map of Asia Minor had been prepared by Col. Bolotoff, and sent to Paris to be engraved; a map of the Caspian sea, and the countries surrounding it, was nearly completed by Mr. Chanykoff; the same savan was
