ANALYs1s.
One gallon contains 217.3 grains of solid matter (3.734 `
grams per liter) composed of calcium sulphate, magnesium
sulphate, sodium chloride, sodium sulphate, ferrous sulphate `
and traces of silica and potassium sulphate.
The iron present as the sulphate (copperas) renders l
the water acid in reaction. '
