Porrett attempted to determine the quantitative composition of prussic acid: he showed that when it is oxidised the volume of carbonic acid formed is exactly twice that of nitrogen, but his other data were erroneous. The problem was solved shortly by Joseph Louis Gay-Lussac. Porrett in 1813 made experiments with Rupert Kirk and William Wilson on the dangerous substance chloride of nitrogen.
