These analyses, it will be obserped, are calculated without carbonic acid. The ash of 

 the ends effervesced strongly ; the middle, less so : in each instance showing the former 

 existence of organic acids, which, by burning, had been converted into carbonate. The 

 ash, however, in each instance, was converted in part into a caustic state. The potato, it 

 is proper to say, was not peeled ; but the outside was well cleansed from dirt by a brush, 

 without abrading the skin.
