An apparatus is described for measuring the magnetic susceptibility of liquids and solutions by the Faraday method. The essential part is a quartz fibre vertical torsion balance. The accuracy of the measurements, which are made by a null method, is of the order of 1-2 parts in 10 000 with diamagnetics.
