of ammonia multiplied by 0.824 will give the corresponding amount of 

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



The laws of 1901 and 1909 abolished this alternative and required 

 that the guaranty shall be given in terms of nitrogen. Many manu- 

 facturers after compljang with the terms of the law, insert addi- 

 tional 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 presented 

 in these tables:

''For the purpose of indicating more specifically to the eye, cases 

 deficient in guarantee, an asterisk has been effixed in the analytical 

 tables where the ingredient has been found less in quantity than the 

 manufacturer guaranteed. Too great emphasis should not be placed 

 upon very slight deficiencies, because very slight imperfections in 

 mixing and slight variations in analysis are practically unavoidable. 

 The asterisk has been used, therefore, only in cases where the de- 

 ficiencies amount to 0.2 per cent, or more, except where nitrogen has 

 been guaranteed in amounts not higher than 1.0 per cent, in which 

 ease an asterisk has been affixed where the deficiency amounts to 

 0.1 per cent, or more."
