A preliminary circular of the French Committee of Organi- 

 zation for the Eighth Session of the International Geological 

 Congress announces the date of the meeting to be held in Paris 

 in 1900. The meetings will be opened on the 16th of August 

 and will be closed on the 28th. They will be held in a building 

 connected with the Exposition, and the hours will be so arranged 

 as to give the members opportunity to visit the Exposition. 



Field excursions are to be made a prominent feature of the 

 session and will take place before, during, and after the meet- 

 ings. These excursions are to be of two kinds, general and spe- 

 cial. The first will be open to as large a number of members as 

 possible, who may be taken to localities where hotel accommoda- 

 tions are adequate. The special excursions are intended for 

 specialists, and since they may necessitate the visiting of regions 

 poorly provided with hotels, the number of members who may 

 participate in each excursion is limited to twenty. To compensate 

 for the small number of geologists admitted to any one of these 

 excursions, the number of excursions is increased to nineteen. 

 This arrangement promises to be a satisfactory solution of the 

 difficult problems connected with the geological excursions, which 

 form so valuable a factor in the organization of the congress. 



Of the general excursions three are announced : 



1. Tertiary Basins of Paris, conducted by MM. Munier- 

 Chalmas, Dollfus, L. Janet, and Stanislas Meunier. 



2. Boulonnais and Normandie, conducted by MM. Gosselet, 

 Munier-Chalmas, Bigot, Cayeux, Pellat, Rigaux — 10 days. 



3. Central plateau of France, conducted by MM. Michel- 

 Levy, Boule, Fabre — 10 days. 



The nineteen special excursions include : 



I. Ardennes, conducted by M. Gosselet — 8 days.
