and value and quality of certain elements which professional 

 chemists call by the same names ; for example, phosphate of 

 lirne, whether mineral or organic, is called phosphate of lime ; 

 potash, whether supplied from felspar or in soluble form, is 

 called potash. In making a report of analyses, chemists are 

 not expected and do not make note of these important differ- 

 ences. They take no note of the fact as to whether ammonia 

 in a fertilizer be in the form of salts, or be generated from ani- 

 mal organic matter ; hence, published analyses may not give 

 a correct basis of value, for all these questions enter in the 

 consideration."

 been more subject to the intrusions of quackery than this very

 of money and time to the consumer, and on the other to create 

 distrust in their minds of those articles that are brought into 

 market by parties possessing all the requisite qualifications as 

 to knowledge of principles involved, and the facilities afforded 

 by ample material resources.' 7 



Little need be said on these stilted quota- 

 tions, they speak for themselves ; and if the 

 reader will compare them with the analyses of 

 their fertilizer, he will be satisfied that they 

 know their duty, but do it not hence the greater 

 the condemnation. 



Rival manufacturers should feel obliged to 

 this company for showing them the qualifica- 

 tions requisite for a successful prosecution of
