disembark at the Portuguese island of San Thomas, the most 
important island of the group, where he will commence 
his work, and where he will be joined by his Haussa 
caravan. He proposes to ascend the mountains in the 
centre of the island, vhich have an altitude of about 5600 
feet, and he will spend altogether about two months in San 
Thomas, exploring and making collections. Mr. Alexander 
will then sail to the most southerly island of the group, the 
Island of Annebon, and on the completion of his work there 
will also \isit Prince’s Island. 
Having finished its work on the chain of islands, the 
expedition will cross to the mainland for the purpose of 
exploration in the Kamerun Colony, for which every assist¬ 
ance will be given by the German Government. The 
first object will be to ascend the celebrated Kamerun 
Peak, which rises to an altitude of 15,000 feet, and which 
the explorer holds to be the sister mountain of Ruwenzori 
in East Africa. He expects that he will find here a fauna 
nearly identical with that of Ruwenzori. The district to be 
traversed is largely unknown, and one of the great difficulties 
will be the lack of water, which will have to be carried by the 
expedition. 
If time and health permit, the expedition will further 
penetrate into the interior of Kamerun, to explore a range of 
hills which are said to attain an altitude of 10,000 feet. 
Travelling is, however, very difficult, owing to the moun¬ 
tainous nature of the country and the difficulties of transport. 
The expedition will probably be absent about twelve months.

“We are now celebrating the Jubilee of the greatest 
Ornithok gical Society in the world, and it has occurred to me 
that we might do something more than is at present being done 
to mark this great event. My suggestion is that we should
