From the official decree of the Superior Council relative 

 to the matter of awards at the coming Exposition in Paris, 

 it appears that the sum of 1,500,000 francs has been appro- 

 priated for that purpose, which sum will be awarded and 

 distributed by a jury composed of three hundred Frenchmen 

 and three hundred and fifty foreigners. The foreign jurors 

 are selected by their respective governments, and those of 

 France by the Superior Council. This international jury is 

 to complete its work between June 1 and September 1, 1878, 

 inclusive. The distribution of awards is fixed for September 

 10, 1878. The rules and regulations for the government of 

 the jury are the same as those of the Centennial Exhibition 

 of 1876.
