Bertoni's 'Aves nuevas del Paraguay.' — Through the kind- 

 ness of our much -esteemed correspondent, Dr. H. von Ihering, 

 of Sao Paulo, Brazil, we have now received a copy of 

 this memoir, a critique on which, by Senor Arribalzaga, 

 has been noticed in a preceding number (' Ibis/ 1903, p. 606) . 

 We think that enough has been said about this production ; 

 but possibly M. Bertoni can justify his statements by sending 

 a set of his birds from the Upper Paraguay (where he made, 

 no doubt, a good collection) to one of the principal Museums 

 of Europe for correct determination. We have little doubt 

 that our fellow-workers at South Kensington would under- 

 take the task. 



Obituary. — Dr. Edward Hamilton. The late Edward 

 Hamilton, M.D., F.L.S., V.P.Z.S., &c, though not a pro- 

 fessed ornithologist, was a much esteemed Member of our 

 Union, to which he was elected in 1886. He died at 

 his London residence, 25 Redcliffe Gardens, South Ken- 

 sington, on the 31st of August last, and will be missed by a 

 large circle of friends and acquaintances, to whom he was 

 endeared by his kind and genial disposition. Hamilton was 

 born in 1815, and educated at Harrow and Uuiversity 

 College, London. Having been a pupil of the late well- 

 known Dr. Quin, he took to homoeopathy, and was for many 

 years one of the most successful practitioners in that branch 

 of Medicine. He had large sympathies with Science, and 

 up to a very recent period was a constant attendant at many 

 of the Scientific Institutions of the West End. At the 

 Councils and Meetings of the Zoological Society of London 

 he was a well-known figure, and was one of the Vice- 

 Presidents of the Society for more than thirty years. In 

 1890 Hamilton published a popular scientific work called 

 ' The Riverside Naturalist/ in which the various forms of 

 life met with on streams and rivers were described, and in 

 1896 a volume on the ' Wild Cat of Europe.' He was also 

 the editor of ' Records of Sport in Southern India/ extracted 

 from the journals of his brother, the late Col. Douglas 

 Hamilton, a well-known Indian sportsman.
