624 The Fourth International 



In the afternoon, meetings of Sections I. and IV. were held. 

 At the first-mentioned, Graf von Berlepsch gave an inter- 

 esting account of some new Neotropical birds, Dr. R. Blasius 

 spoke at some length on the never-ending theme of 

 nomenclature, and Dr. Louis Bureau read a paper dealing 

 ■with the Roseate Tern on the coast of Brittany. In the 

 fourth Section, that devoted to Economic Ornithology, a

 read a paper on the Protection Laws in Great Britain and 

 Ireland, regretting the absence of uniformity in the various

 lecturer had hitherto seen. Great stress was laid on the two

 change as brought about by abrasion, which was followed 

 by a short paper by Dr. Leverkuhn on the nesting of the 

 Egyptian Vulture and Imperial Eagle. Herr Otto Herman's 

 paper on Bird-Migration, a summary of which was read in 

 English by Mrs. Ilona Ginever, dealt, in the first place, with
