SAFETY OF COL. PREJEVALSKY. 
A letter has been received at St. Petersburg through Pekin from Col. Pre- 
jevalsky, dated from the town of Si-Ning, March zoth, announcing that the 
expedition under his command is safe. He left the Nan Shian mountains in 
July, and entered Thibet through Shaidash. His party was attacked by Tanguts, 
of whom they killed four and put the remainder to flight. The Thibetian troops 
stopped the progress of the expedition 250 versts from Hlassa, and a messenger 
from the Grand Lama of Thibet brought the refusal of the Thibetian authorities 
to allow the Russians to proceed. The latter were therefore obliged to return, 
which they did with some difficulty through Northern Thibet, wintering at a 
height of 16,000 feet above the level of the sea. Col. Prejevalsky expects to 
reach Kiakhta in August by way of Alashan Urgu. 
ANTARCTIC EXPEDITION. 
The bulletin of the Italian Geographical Society for April contains full 
details of the proposed Antarctic Expedition under Lieut. Bove, with a carefully 
compiled map of the south polar regions so far as these have been hitherto 
explored. 
AN UNKNOWN REGION IN SOUTH AMERICA. 
The work of exploration has been carried forward to such an extent that few 
portions of our globe remain unknown to men In this work geographical socie- 
ties have vied with each other, and the various governments have been lavish in 
expenditure. The poles are still a ¢erva cncognita, but under the plan of Capt. 
Howgate the North Pole will probably very soon give up its secrets. He is pre- 
paring to establish with his present expedition a colony, at a high latitude, at a 
point where they have recently discovered an immense bed of coal. This colony 
can be recruited with men, and supplied with provisions, and expeditions con_ 
ducted with sledges over the ice, starting at such a latitude and taking advantage 
of the season, will have everything in their favor for reaching the pole. 
In South America there is also an unknown region. Much has been done 
on that portion of the American continent by Humboldt, Orton and others by the
