SCIENTIFIC CONGRESS OF CARLSRUHE. 375 



Konigsberg, on the northern confines of Germany. Nor should it be 

 forgotten that England also holds a scientific congress, and, like the 

 others, in the month of September. Each of these assemblages will 

 place in requisition a certain number of men of science and prevent 

 them from attending elsewhere, notwithstanding the present celerity of 

 travel. To escape from this difficulty, it remains to take a step which 

 will be effected sooner or later, that is, to substitute for all these par- 

 tial reunions a scientific congress for all Europe, to be replaced here- 

 after, in turn, by a Universal Scientific Congress, which shall sit, in order 

 of succession, in the principal cities of the old and new continents.
