(1) loc.c. of the standard sulphuric acid were equivalent to 66.8 c.c. baryta solution 

 and yielded 0.600.603 gram barium sulphate. Hence 1 c.c. of the baryta solution = 0.001094 

 gram nitrogen. 



(2) 10 c.c. of the standard sulphuric acid were equivalent to 19.75 c.c. soda solution, 

 and 1 c.c. of the soda solution =0.004364 gram nitrogen.
