obtained by Dr. Lorentz in New Guinea, amongst which 

 were examples of some species not yet described ; and 

 Oberlehrer W. Capek on a large series of Cuckoo's eggs, of

Migration was very fully discussed in the second Section. 

 Ritter von Tschusi zu Schmidhofen was unfortunately pre- 

 vented by illness from attending the Congress, but sent a 

 paper on the incursion of Crossbills in 1909. Dr. Hugo 

 Weigold, of Heligoland, proposed to establish a Bird- 

 observatory on that island, on the same lines as that of 

 Rossitten, and gave a description of the island as it was in 

 Giitke's time and as it now is. Capt. von Lucanus went fully 

 into the question of the altitude which birds attain on 

 migration, and stated his opinion that they do not travel at so 

 great a height as had been surmised by Gatke. Director Otto 

 Herman gave particulars of the work done by the Royal Hun- 

 garian Ornithological Bureau of Budapest, and Dr. Rossler, 

 of Agram, gave an account of what has been done by the 

 Croatian Ornithological Bureau. Dr. Thienemann, the 

 Director of the Observatory at Rossitten, contributed par- 

 ticulars of the results obtained by marking different birds 

 in order to ascertain their routes of migration, and where 

 they go to in the winter. Dr. Jacob Schenck gave details 

 of the investigations carried on at Budapest respecting 

 migration, and remarks on the same subject were made by 

 other Members. 



Hird-protection was most fully discussed by Mr. Dutcher, 

 Mr. James Buckland, Dr. Rorig, Dr. Heuss, and others, and 

 Dr. Heuss and Mr. Buckland strongly advocated the necessity 

 of establishing an international union for bird-protection in 

 all countries. Frau van Hoorde spoke of ladies' fashions with 

 regard to bird-protection, and Professor Schillings urged 

 strongly the advisability of prohibiting the importation of 

 the skins and feathers of birds for decorative purposes. 

 After considerable discussion it was finally decided to con- 

 stitute a permanent International Union for the protection 

 of birds in civilized countries, and the following members 

 were elected to serve on it : — Austria, Professor Schweder ;
