Dr. Radde } s List of Travels and Publications. —With a 
copy of the ‘ Museum Caucasicum 9 (noticed above, p. 392), 
Dr. Radde kindly sends us a useful summary of his travels 
and expeditions, as well as a list of his chief publications, 36 
in number, besides numerous minor articles. These serve to 
show at a glance the large amount of good work this veteran 
zoologist has accomplished since he commenced his investi¬ 
gations on the natural history of Southern Russia in 1854. 
For the past 35 years the Director of the Caucasian Museum 
has devoted his entire attention to the country in which he 
resides, and no fewer than 24 of the publications relate to his 
numerous expeditions in various parts of the Caucasus and 
the results consequent thereon. 
The Ornithological Outlook at Lake Kivu. —The last number 
of Danckelman’s f Mittheilungen von Forschungs-Reisenden 
und Gelehrten aus den Deutschen Schutzgebieten ? (vol. xii. 
p. 235) contains a letter (dated August 12th, 1899) from 
Dr. R. Kandt announcing that he had established himself in 
a <l Zoological Station 99 at Bergfrieden, on the south side of 
Lake Kivu, and had been devoting himself mainly to 
ornithological work. We fear, therefore, that disappoint¬ 
ment may be in store for our friends Messrs. Mathews and 
Berridge, who are with Mr. Moore’s Tanganyika Expedition, 
and who hoped to pass through an unexplored country 
between the north end of Lake Tanganyika and Lake Albert 
Edward. At the same time, whatever birds they may bring 
from that far-distant spot will be certainly new to us in 
England. At the date of the last letter (Nov. 7th, 1899) 
received from the Expedition, the party were still on Lake 
Tanganyika, where they had arrived on Sept. 20th, and were 
all in good health, except Mr. Berridge’s servant, who had 
been invalided home. Messrs. Berridge and Mathews were 
at Sumba, shooting and collecting.
