Karema on account of the hostility of the natives. He descended 
the Luapula for some distance, and found that, as shown in Raven- 
steins map of Eastern Equatorial Africa, this river flows out of 
the south-west side of Lake Bangweolo. Dr. Pogge died at St 
Paolo de Loanda on March 17th. The bay of Angra Pequeña, 
27° N. lat., on the coast of Great Namaqua land, has recently 
been taken possession of by Germany. It is curious that upon 
the maps, even on those of the Germans themselves, this spot is 
marked as belonging to England, Robert Flegel continues his 
explorations of the Niger and the Benua. While waiting for funds, 
he joined the Swiss explorer, Zweifel, in a voyage upon the lower 
course of the Niger. This exploration has given us a map of the 
Niger and its affluent the Amambara. On his return to the coast 
M. Flegel found himself able to continue his work, and reached 
Loko on September 11th.
