tionof i to 6. But the amount of 1-25 francs was in the 

 last discussion in the Council reduced to 30 centimes, which 

 it seems the Jablochkoff Company have accepted, as the 

 lighting is continued. We think, however, that under these 

 conditions the company must be out of pocket, for accord-
