(6) Proposition by M. OLhlert on the reproduction of types. 

 M. Tietze proposed to the meeting, on the part of the Austro- 



Hungarian Government, to organise in three years a new Session 

 of the International Geological Congress at Vienna. He in- 

 formed them of the advanced state of the preparatory work for 

 such a congress, and enumerated the many excursions which 

 would be arranged for the members of the Congress. 



The invitation of the Austro- Hungarian Government was 

 unanimously accepted, and M. Tietze thanked the Congress for 

 the warm reception given to his proposal. 



Papers : — Matthew, on the most ancient Palaeozoic fauna ; 

 IVakott, the pre-Cambrian fossiliferous formations ; Cayeux, 

 on the radiolaria and sponges of the pre-Cambrian rocks of 

 Brittany ; Pavlow, the Portlandian rocks of Russia compared 

 with those of the Boulonnais ; on some means which would con- 

 tribute to the determination of the genetic classification of 

 fossils ; Van den Broeck, on the age of the deposits of the 

 Iguanodons of Bernissart ; Guibhard, disturbances and frac- 

 tures of the folds in the Alps of France ; Stanislas- Meunier, 

 structure of the diluvium of the Seine ; Hull, sub-oceanic 

 terraces and valleys of the rivers of the western coast of 

 Europe ; Hudleston, the eastern shores of the Atlantic ; 

 E. Martel, on the recent discovery of large caverns and fissures. 



During the Congress receptions were offered to its members, 

 first by the Geological Society of France, at their new rooms in 

 the Hotel des Societes Savantes. The president of this society, 

 M. A. de Lapparent, of the Institute, inaugurated this reception 

 by an address, which was warmly applauded. M. and Mdme. 

 Albert Gaudry invited the members of the Congress to their 

 house to a most brilliant soiree. Prince Roland Bonaparte 

 received at his hotel the united members of the Geological and 

 Anthropological Congresses, who were also received together by 

 the Municipal Council at the Hotel de Ville of Paris. 



The Committee of Organisation offered a most brilliant 

 banquet at the Hotel du Palais d'Orsay ; the addresses of 

 M. Albert Gaudry, Sir Archibald Geikie, and MM. Tietze, 

 Credner and de Lapparent were warmly applauded. Finally, 

 cards for a reception at the Elysee, and tickets for the National 

 Theatre, were placed at the disposal of the president by the 

 Minister of Public Instruction and the Fine Arts, for distribu- 

 tion among the foreign members. Visits were arranged by the 

 aid of the Committee, to the International Exhibition, the 

 National collections of geology and mineralogy, to the 

 Museum of Natural History, to the Sorbonne, and to the 

 School of Mines. 



NO. 1614, VOL. 62] 



The excursions of the Congress were well attended. The 

 programme submitted to the geologists of the whole world was of 

 the most tempting description. A pocket-guide, prepared by 

 the united efforts of the French geologists, gave in several 

 numbers a complete account of the geology of France. 



In order to allow everyone to take part in the greatest number 

 of excursions, they were divided into three periods : before, 

 during, and after the Congress. 



(i) Excursions before the Congress : Ardennes, conducted by 

 M, Gosselet ; Gironde, by M. Fallot ; Touraine, by M. G. 

 Dollfus ; Pyrenees (crystalline rocks), by M. Lacroix ; Aquitania 

 (Charente et Dordogne), by M. Glangeaud ; Turonian of 

 Touraine and Cenomanian of Le Mans, by M. de Grossouvre ; 

 Mayenne, by M. D. P. CEhlert ; Brittany, by M. Barrois. 



(2) Excursions during the Congress : Tertiary basin of Paris, 

 MM. Munier-Chalmas, Leon Janet, Stanislas-Meunier and G. 

 Dollfus. 



(3) Excursions after the Congress : Boulonnais and Normandy, 

 MM. Gosselet, Munier-Chalmas, Pellat, Rigaux, Bigot, Cayeux ; 

 Central Rocks, MM. Michel-Levy, Marcellin Boule, Fabre ; 

 Coal-basin of Central France, MM. Fayol, Grand'Eury ; 

 Tertiary basins of the Rhone ; Secondary and Tertiary rocks of 

 the Lower Alps, MM. Deperet, Haug ; Alps of Dauphiny, 

 MM. Marcel Bertrand, Kilian, Lory, Paquier, Sayn, Leenhardt, 

 Termier ; Picardy, MM. Gosselet, Cayeux, Ladriere ; Range of 

 the Black Mountains, M. Bergeron ; Pyrenees (sedimentary 

 deposits), M. L. Carez ; Lower Provence, MM. Marcel 

 Bertrand, Vasseur, Ziircher. 



These excursions, beginning on August 3, ended on October 

 2, and have had therefore a duration of three months. 



The next meeting of the International Geological Congress 

 will be held at Vienna in 1903. L. Gentil.
