Dr. Radde's List of Travels and Publications. — With a 

 copy of the 'Museum Caucasicum ^ (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 1851. 

 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 ' Mittheilungen von Forschungs-Reisenderi 

 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 " Zoological Station " 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.
