a Includes (FeMn)COi. ((Complete analysis in Table V. 



N. B. Blank spaces in above table denote that no tests were made. 



REMARKS ON TABLE VI. 



The above figures for calcium and magnesium carbonates have been calculated 

 from the lime aud magnesia actually found. With exception of two numbers indicated
