II. The a chin en sis (a). 
Total nitrogen in fresh leaves. (Nov. 1895). 
(i) io c - cm - of the standard sulphuric acid contained 0.237548 g. of sulphuric acid and 
corresponded to 0.067873 g. of nitrogen ; io.c- cm. 0 f the sulphuric acid corresponded to 
36.2c. cm. 0 f baryta water, ic. cm. baryta water = 0.001875 g. of nitrogen. 
(2j A molecule of asparagine contains two atoms of nitrogen and as by boiling it 
with hydrochloric acid only one atom is split off as ammonia, the result must be doubted.
