In the case of root (a) and bark (a) 1 cc. baryta water 
— 2.14806 mgm. nitrogen and in the case of root (ß), bark (ß), 
leaf A, Leaf B, and leaf C, 1 cc. baryta-water = 3.12445 mgrn. 
nitrogen but only in the case of leaf A in proteid nitrogen deter¬ 
mination i cc. of baryta-water = 177115 mgm. nitrogen.
