hydrochloric, or muriatic acid. J believe it will be found, 
that, that compound (carburet of azote) is the basis of the mi- 
asmata, which produce malignant bilious diseases ; and it is 
equally certain, that similar causes, actin er cir- 
cumstances will generate it in the cities of New-York, Phila- 
delphia, or Baltimore, as in the West-Indies. We admit, 
as in the formation of nitric acid in artificial nitre beds, by 
the concurrent corruption of animal and vege substan- 
ces, that nascent azote unites with oxygen, furnished by free 
air, which attaching itself to an alkaline or earthy base, as 
the case may be, produces an alkaline or earthy nitrate, and 
that calcareous substances. facilitate considerably the union 
of azote and oxygen. _ This is the oneal course of that pu- 
originated as well as the azote from the paaetacae” substan- 
ces. Whether oxygen unites directly with azote in a nas- 
cent state, or separates the azote from hydrogen, in amm 
may infer, that either the ammonia was decomposed, or 
that the acid itself combines with it, forming nitrate o 
monia. Here th then we have two inst ances of the combina- 
thus become acidified. Hydrogen, as it is a solvent of 
carbon, sulphur, phosphorus, &c. may be evolved in com- 
bination, as we find more particularly the case in the pe- 
culiar miasmata, evolved from marshes, and low wet land, 
which appear to be produced in such cases by weceraus 
decomposition. Marsh miasmata are generally the cau 
of intermitient fevers. Now under particular cirewinstate 
ces ofaction, may we notadmit the generation of carburet of 
of azote, or cyanogene? And if so, as it readily unites with 
hydrogen, may it not be the miasma, which produces ma+ 
lignant bilious ee since it is known that hydrocyanic
