ANALYSES. 229 



THE EXCELLENZA AMMONIATED 

 SOLUBLE PHOSPHATE. 



The above phosphate, from which samples 

 for analyses were selected, was purchased from 

 Messrs. Dugdale & Girvin, Baltimore. It is put 

 up in bags marked 200 Ibs. ; the one purchased 

 weighed 198 Ibs. Its mechanical condition was 

 good. Messrs. Dugdale & Girvin state in their 

 circular that : 



" We have been at special pains in the manufacture of the ' Ex- 

 cellenza,' to produce a greater amount of soluble material for the 

 price, than any other fertilizer with which we are acquainted." 



They also give an endorsement and analysis 

 of Professor Chandler, as follows : 



" SCHOOL OF MINES, COLUMBIA COLLEGE. 



"NEW YORK, September 26, 1870. 



"I have examined the 'Excellenza' ammoniated superphos- 

 phate of lime, and find it to be an excellent article, containing from 

 14 to 15 per cent, of soluble phosphoric acid, which is a very 

 unusual percentage. It also contains a very good percentage 

 of ammonia, or ammonia-producing materials. It is one of the 

 best fertilizers in the market, and is superior to most of the other 

 superphosphates. " C. F. CHANDLER, Ph. D.,
