The ‘nitrum’ mentioned by Pliny, which gave off a strong smell on being sprinkled with lime, must have been a salt of ammonium, probably the chlorid; but potassium nitrate (the niter or saltpeter of the present age), and also calcium nitrate, potassium carbonate, sodium chlorid, magnesium sulphate, and the sulphates of zinc, iron, and copper (later distinguished as metallic vitriols) were probably more or less confounded under the general name.
