 mach 2 inches in diameter, with a pyloric lobe 10 twelfths 

 in breadth ; intestine 9 feet 1 inch long, from 8 to 2 twelfths 

 in breadth. Of the second, the oesophagus was 26 inches 

 long, H inch wide at the proventriculus ; stomach 1^ inch 

 in diameter, with a pyloric lobe 8 twelfths in breadth ; intes- 

 tine 6 feet 7 inches long, its average width 2 twelfths.
