parts of livdiogcMi ami rourteen pails oT iiilroj^i'ii, it is a very simpU' 

 matter to calculate the ainoiiut of one, when the amount of the 

 other is given; the amount of nitrogen multiplied by 1.214 will give 

 the coiTespondiug amount of ammonia, and the amount of am- 

 monia multiplied by 0.824 will give the corresponding amount of 

 nitrogen. In these tables, the expression is in terms of nitrogen. 



The law of 1901 abolishes this alternative and requires that the 

 guaranty shall be given in terms of nitrogen. Many manufacturers 

 after complying with the terms of the law, insert additional items 

 in their guaranties, often with the result of misleading or confusing 

 the buyer; the latter will do well to give heed to those items only 

 that are given as the law requires and that are pros.nted in these 

 tables.
