desirable. The conclusion recently published by the Com- 

 mission presided over by Sir David Bruce, that the human 

 trypanosome disease of Nyasaland is Nagana, shows that the 

 problem may be complicated by factors which have not been 

 taken sufficiently into consideration up to the present time. 



The small mammals exhibited belonged to species which have 

 been recorded as " hosts " of the fleas which transmit plague in 

 India and elsewhere. 



The predaceous birds and the Indian cobra were illustrated 

 as some of the enemies of these small mammals, or of insects 

 which transmit diseases. 



A number of species of blood-sucking insects and ticks (the 

 latter a group which is more nearly related to the spiders than 

 to the insects) were illustrated by means of specimens. 



Another part of the exhibit consisted of maps illustrating 

 the geographical distribution of blood sucking insects instru- 

 mental in the spread of disease, particularly Tsetse-flies, 

 Plague-fleas, and Stegomyia fasciata, the species of mosquito 

 which disseminates yellow fever. 



Some of the publications of the Museum which include 

 accounts of blood-sucking insects of economic importance were 

 shown. 



The Board of Trade have reported that the Museum exhibit 

 attracted considerable and wide interest, and that it was visited 

 by many medical men and experts on the subject, British and 

 foreign. 



Mr. C. E. Fagan, I.S.O., was appointed to act as one of the 

 members of the Organizing Committee of the British Section, 

 and Mr. E. E. Austen and I)r. W. G. Ride wood were associated 

 with him in the work, and supervised the preparation of the 

 specimens. 



The British Antarctic " Terra Nova" Expedition, 1910. 



The collections brought home by the Antarctic S.S. "Terra 

 Nova " have been handed over to the Trustees, who have 

 undertaken to prepare and publish the report of the natural 

 history results of this Expedition on the same lines as the 

 report of the collections of the *•' Discovery " Antarctic 

 Expedition, which was also published by the Trustees. 



The present work will certainly run into several volumes, 

 and, when completed, it should be a worthy and fitting memorial 

 of the natural history explorations in the Antarctic made by 

 the late Captain Scott and his companions. 



Investigation of Antarctic Whales. 



The Trustees have continued to give their attention to the 

 subject of the protection of Whales in Antarctic Seas with a 

 view to measures being taken to prevent the extinction of 

 these animals. In this connection, the importance of obtaining 

 a further knowledge of the life-history and habits of the whales
