EXPERIMENT XXXVIII.

A piece of putrid flesh which had been sweetened by the vapours of iron

filings and the nitrous acid, had a pungent, acidulous smell. It was

carefully washed in water, and still remained free from putridity. A

few drops of lixivium tartari were instilled into this water without

producing any sensible effervescence.

May we not infer from these experiments, that if fixed air be an acid,

it is an extremely weak one, and not sufficient, as such, to sweeten

putrid bodies; which effect must consequently be owing to some other

mode of action, the principles of which are not as as yet positively

defined?
