THE SIXTH INTERNATIONAL CONGRESS 

 OF ZOOLOGY. 



T^'HIC smoothness with which the complicated arrangements 

 ■'■ lor the reception and housing of so many guests were 

 carried out, and the kindness and hospitality of the welcome 

 e.\tended to them, formed a good augury for the success of 

 the sixth International Congress of Zoology, which opened 

 at Berne on Monday. August 15. On the previous day the 

 members, gathered from many parts of the world, were 

 received by the reception committee at the railway station, 

 and invited afterwards by the Mayor of the city to a 

 " symposium " in the " Kornhauskeller." The gaiety of 

 the assembly, which did not breali up until a late hour, 

 formed an agreeable prelude to the work of the congress, 

 which was throughout interspersed with pleasant entertain- 

 ments. 



At the general meeting the next morning Prof. Studer, the 

 president, chose as the subject of his address the Swiss 

 fauna, to the study of which he has devoted so much of 

 his life. Prof. Perrier, of Paris, as president of the 

 permanent committee, thereupon expressed his feelings of 

 gratitude to the Swiss Government and to the authorities 

 of the canton of Berne for the hospitality which had been 

 extended to the members of the congress. The following 



NO. 1 8 19, vol.. 70] 



gentlemen, Tiofs. Studer, Minot, Grassi, and Perrier, were 

 afterwards elected presidents for the general meetings, and 

 Profs. Emery, Fujii, Spengel, Osborn, v. Graff, Pelseneer, 

 Lonnberg, Blanchard, Chun, v. Wijhe, Lang, and Drs. 

 Horvath, Stejneger, Stiles, and Miller as vice-presidents. The 

 meeting also agreed to divide into seven sections, viz. : — 

 General Zoology, president. Prof. Salensky ; vice-president, 

 Mr. Schlumberger ; secretary. Dr. Gurwi'tsch. Vertebrata 

 (systematic), president. Dr. Jentink ; vice-president. Dr. 

 Scharff ; secretary. Dr. Andr^. Vertebrata (anatomy, &c.), 

 president. Prof. Monticelli ; vice-president. Dr. Bashford 

 Dean ; secretary. Dr. Penard. Invertebrata (excluding 

 Arthropoda), president, Prof. Ehlers ; vice-president. Prof. 

 Koehler ; secretary, Dr. Fuhrmann. Arthropoda, president. 

 Prof. Heymons ; vice-president, Dr. Janet ; secretary. Dr. 

 Steck. Applied Zoology, president, Prof. Hoek ; vice-presi- 

 dent. Prof. Plate; secretary, Dr. Duerst. Zoogeography, 

 president. Prof. H^rouard ; vice-president, Prof. Blasius ; 

 secretary. Dr. Roux. 



Two propositions had been received by the president, Prof. 

 Studer, one from the Prince of Monaco, to hold the next 

 congress at Monaco, and another from the zoologists of the 

 United States of .America. After due consideration of these 

 proposals, it was decided by the permanent committee and 

 by the delegates of the scientific societies to recommend that 

 the latter invitation be accepted, which was unanimously 

 adopted at the general meeting. It was therefore agreed 

 that the ne.xt congress, in 1907, should be held at Boston, 

 and that Prof. Agassiz be asked to preside. Prof. Minot 

 expressed the hope that it might be possible to place at the 

 disposal of the European zoologists a large steamer, which 

 would call for them at Hamburg, Cherbourg, and South- 

 ampton. 



Subsequently, Prof. Blanchard gave an interesting 

 address on the production of disease in man by animal 

 parasites, and also pointed out in how many ways zoological 

 discoveries had aided not only the elucidation and diagnosis 

 of disease, but also its cure ; after which Prof. Lang made 

 some remarks on the life of the Swiss naturalist, Alexander 

 Morizi, born in 1806 at Chur, who, some years before the 

 appearance of Darwin's " Origin of .Species," had pub- 

 lished a paper in which he promulgated the theory of 

 evolution and supported the view that man had evolved 

 from the higher animals. 



At one of the later general meetings. Profs. Salensky, 

 Osborn, Chun, Hoek, and Sarasin delivered addresses. Prof. 

 Salensky referred to the results of the most recent investi- 

 gations of the life-history and anatomy of the mammoth, 

 and exhibited photographs of a specimen in situ (already 

 noticed in Nature), as well as preparations of the skin, 

 muscles, hairs, &c. It seems now to be a well established 

 fact that the mammoth was a northern species feeding 

 especially on conifers, but also on cyperaceous, gramin- 

 aceous, and leguminous plants. The recently discovered 

 stages in the evolution of the horse and contemporary 

 mammals in North America formed the subject of Prof. 

 Osborn 's lecture, while Prof. Chun dealt with the vertical 

 distribution of the marine plankton. 



Altogether more than four hundred zoologists, many of 

 whom brought one or more members of their family, took 

 part in the congress. The general meetings were held in 

 the large hall of the Swiss House of Parliament, and the 

 sections met in the lecture rooms of the splendid university 

 buildings, of which the country is justly proud. 



L — General Zoology. 



It has been assumed that the South American Stegomyia 

 was the means of transferring a blood parasite to man, 

 which gave rise to yellow fever; Prof. Goeldi, of Para, 

 however, gave reasons for his belief that this disease is 

 not due to any blood parasite, but to an organic toxin which 

 he discovered in the saliva of Stegomyia. 



The zoological aspect of De Vries's mutation theory was 

 discussed by Prof. Plate, who recognised that the theory 

 signified an important advance of knowledge in so far as 

 it showed that sudden changes could arise in the organism 

 which were highly transmissible, but he urged that a sharp 

 morphological boundary could not be drawn between 

 variations and mutations. The former must be considered 

 as changes with a slight capacity of inheritance, the latter 

 as such with a high capacity.
