ANALYSES. 247 



" Marl, one of the constituents of Bromophyte, is valuable 

 for various reasons it is a composition of clay and shells, the 

 clay being the more important substan.ce of the two. Its very 

 valuable properties were first pointed out by Professor Way, 

 Chemist of the English Royal Agricultural Society. He says 

 that clay will decompose the salts of ammonia, potash and soda, 

 and retain their bases." 



"At the close of Mr. Taylor's remarks, Mr. William Saun- 

 ders. of the Agricultural Department, proposed a vote of 

 thanks to Mr. Taylor for his valuable remarks, which was 

 unanimously carried. 



" The following statement has been received from Professor 

 Blaney, of Chicago, relative to the merits of Brornophyte : 



" CHICAGO, October 26, 1870. 



"This is to certify that I have examined the specimens of 

 Brornophyte submitted to me, and have found the same to be 

 composed as follows : 



Volatile matter, organic matter, water and a 



trace of free ammonia 59-05 



Inorganic matter 40*95 



The Brornophyte contains of salts 40*95 per cent., namely : 



Sulphate of Lime 17-6765 



Phosphate of Lime 1-4922 



Phosphate of Magnesia 1-1335 



Carbonate of Magnesia 2-2613 



Chloride of sodium 2*0540 



Sesquioxide of Iron and Alumina 5*0790 



Insoluble Silicates 11-2690 



Chloride of Potassium, a tra^e. 



Total 40-9655 



Gain -0155 



40-9500 



"The Broraophyte was found by organic analysis to contain 

 nitrogen, 3-92 per cent., equivalent to ammonia, 4*76 per cent. 



'JAMKS V. T. BLAXKY, 

 "Analytical and Consulting Chemist." 



" P. S. It will be seen, by comparing with analysis of guano, 

 that Bromophyte is two percent, the stronger."
