The Polar Expedition of Dr. Hayes. 263 
_ Levean’s Expepitioy To Gonpoxoro.—Mr. G. Lejean, who 
is said to have been aided in his outtit by the Emperor of the 
French, set out early in 1860 from Chartum, and went south, 
hoping to find the source of the White Nile in the Lake Nyanza 
Speke,—the same end in part which Mr. Petherick proposed 
to himself. Lejean reached Gondokoro, and was then prevented 
by illness from pushing his explorations farther. But the Jour- 
of the Geographical Society of Paris gives us reason to ex- 
ae, ots trom his investigations in Eastern Soudan and 
ubia. 
RoscherR aND von per Decken.—Karl vy. d. Decken, a 
fiend of the late Dr. Roscher, (murdered in his attempt to reach 
¢ Nyassa from the East African coast,) endeavored to prose- 
cute the discoveries of Roscher, but was robbed and driven back. 
A recent letter to Sir Roderick Murchison says that v. d. Decken 
will now try to reach the peaks of Kilimandjaro.

as already been mentioned in this Journal, (xxxii, 452). Im- 
in part he went forth, in respect to the results which his expedi- 
fon accomplished. A few deve later he addressed the ye 
of Natural Sciences in Philadel phia upon the same subject. Full 
Teports of these communications have been made in the newspa- 
Pets of the day, but so far as we are aware Dr. Hayes has not 
ble any complete authentic account of his voyage. In- 
it is too soon to expect him to do so.* 
Tn a letter addressed to Prof. B. Silliman, Jr., he speaks as 
follows in reference to one of these addresses: “You will un- 
derstand that I do not undertake in it a discussion of results, for 
MY materials are yet unreduced. I shall merely describe what 
Tq and what was done in behalf of the science of the Arctic 
ions, My materials are I believe of much value. Since the 
Th. of Mr. Sonntag I have labored almost alone and of course 
have not done all that might have been accomplished by a corps 
of workers, e duties of my command occupied much of my

Views. Of these I have nearly two hundred, many of them quite

American) will be font Littell’: Living SS Saaanry 4, 1862.
