 principle of heating, and in this manner has considerably 

 increased the illuminating power of the gas. He has 

 thereby not a little retarded the victory of the electric 

 light over gas, which however has not produced a jar 

 in our fraternal harmony. After William's death he 

 undertook the latter' s furnace business in England, 

 and has continued it with the best success. An amiable 

 wife and a charming troop of children will, we may
