PresidenfH Address. xix 



he ever met with of the very rare hawk, PoUohierax semitorquatus. 

 Several of his birds proved to be new to science, and I had the 

 pleasure of describing two of them, viz., a Eacket-tailed EoUer ( Coracias 

 spatulatus), and a Yellow-breasted Shrike {Laniarius atro-croceus). 

 Dr. Bradshaw's health was seriously undermined by the hardships 

 attendant on his Zambezian journeyings, and never afterwards really 

 rallied. He had filled several district surgeoncies in the Colony, and 

 in 1880 was appointed surgeon to the Northern Border Police. On the 

 Orange Biver he was for some time in better health, but in 1882 had 

 to visit England for change and medical advice. He returned without 

 having deiived much benefit ; and a long Karroo journey on duty 

 proved too much for his weakened state. He died on 1st December, 

 1883, in his thirty-sixth year. Singularly straightforward, unworldly, 

 and of simple tastes and habits. Dr. Bradshaw possessed great resolu- 

 tion and endurance, combined with a gentleness and kindness that 

 endeared him to his friends and fellow officers. 



Emil Elmgren, whose paper "On the Form of Cross Section of a 

 Channel for Constant Velocity of Water at different depths " has been 

 mentioned above, and will be published in the '' Transactions," was 

 a native of Sweden. His mathematical knowledge was considerable ; 

 and he had designed and hoped to construct a calculating machine — 

 the merit of which was recognised by both the Astronomer-Eoyal and 

 the Hydraulic Engineer. He was a great sufferer from pulmonary 

 disease, to which he succumbed in February last. 



9. In response to an invitation published in Nature of the 26th 

 March last by the British Association for the Advancement of Science, 

 application has been made to that body to have our Society recognised 

 as one in ''correspondence" with it. This designation is by the 

 Association's recently adopted rule limited to societies issuing publica- 

 tions devoted to research, and specimens of such publications are 

 required to accompany every application for recognition as a •' Corres- 

 ponding Society." In the probable event of our request being granted, 

 we shaU have the privilege of nominating a delegate to represent the 

 Society on the general committee at each successive annual meeting 

 of the Association. 



10. After having for so long profited by the liberality of the Uni- 

 versity authorities in according us the use of their premises, the 

 Council at length thought it advisable to make the experiment of 

 engaging a room centrally situated for the purpose of holding the 

 Society's meetings, and succeeded in obtaining the side-room of the 

 Commercial Exchange at a moderate charge. I think that the members 

 generally will agree with me that, alike in situation, dimensions, and 

 convenience, this apartment is well adapted to our requirements. By 

 its acquisition, moreover, we shall be able, through the courtesy of the 

 Committee of the Exchange, and of their Secretary, Mr. A. Ellis, to 

 render our Library more accessible by removing it to our new quarters • 

 thus saving the rent hitherto paid for the room in which the books 

 have been kept. 



11 . The mention of our Library reminds me that it has received 

 considerable additions during the past two years, in the way both of 

 donations and exchanges, for our own Transactions. Among the 

 donations are especially noticeable those received from Vienna, at the 

 instance of our fast friend Dr. Holiib, consisting of the complete 

 <'Mxttheilungen" of the Vienna Ornithological Society, and aeon-
