If we review the estimates from the two systems of formule, 
and the results of analysis recorded above, it will be seen— 
1st. That the analyses of the compounds with nitrate of silver, 
more nearly correspond with the estimates from Boussingault’s 
formul 
ula. 
2d. That the analyses of the compounds with nitric acid, ni- 
trate of potash and nitrate of copper, are suited equally well to 
either formula. d 
3d. That the analyses of the remaining compounds, viz: with 
the oxyds of silver, copper and lead, correspond more nearly with 
the simpler formula. 
As additional reasons for adopting the simpler formula, the fol- 
lowing, drawn from our investigation, may be recorded. 
th. The analyses give this constitution: as the average of 
four combustions for carbon and hydrogen, and two for nitrogen, 
will show, placed side by side with the estimates from the formu
