of a new detonating Compound, *j 



The mechanical force of this compound in detonation, seems 

 to be superior to that of any other known, not even excepting 

 the ammoniacal fulminating silver. The velocity of its action 

 appears to be likewise greater. 



I am, my dear Sir, 



with great respect, very sincerely your's,
