This agreement has been come to principally through the 
exertions of a small committee consisting of Lord Rothschild, 
Sir Sidney Harmer, Dr. Lowe, and representatives of the 
trade, who have had many meetings at the Natural History 
Museum before they arrived at this compromise, which is 
apparently agreeable to both parties concerned. 
Personalia. 
We learn that Dr. Erwin Stresemann has been appointed 
Curator of Birds of the Zoological Museum of Berlin, in 
succession to Dr. Anton Reiehenow who retires, having 
reached the age of 74. Dr. Reiehenow succeeded Dr. 
Cabanis in 1892, and had therefore been about thirty years 
in the Berlin Museum. Dr. Stresemann spent some months 
in England in 1913 working out the collection of birds made 
during the second Freiburg Moluccan Expedition in which 
he took part in 1910-1912; during this journey he visited 
several of the East India Islands, including Bali and Ceram. 
Since the war he has been working with Dr. Hellmayr in 
the Museum at Munich. 
Mr. A. de C. Sowerby, M.B.O.U., has recently left 
England for China, where he will spend the next few years 
carrying on explorations in the south and west of a biological 
nature, on behalf of the United States National Museum at 
Washington. He intends visiting the mountainous areas 
of Chekiang and Eokien, thence working round to Canton 
Province and Kwangtung, and visiting Hainan Island. Birds 
will occupy a special place in his programme, and he hopes 
to make extensive collections. 
Mr. J. R. Kinghorn of the Australian Museum at Sydney 
has recently been appointed a first-class assistant in charge 
of the collection of Birds in that Institution.
