In the case of bone, fish and superphosphates, a still closer 

 agreement would probably have been obtained by the two 

 reagents if the materials analyzed had admitted of finer pulver- 

 ization and more accurate sampling. 



A considerably larger number of comparisons have been made, 

 but in no case, except that of strychnine, was the difierence 

 greater than is indicated by the determinations above given. 



The combustion of strychnine is more difficult than that of the 

 other substances named above, and for good results it is needful 

 to use it in small quantities, as seen from the subjoined statement.
