Stokes' law, with a modified form of Ladenburg's wall‐correction factor, has been applied to determine the viscosity of glass from the velocity of a freely falling platinum sphere. The apparatus is described in full, a special feature being the radio equipment used to measure the velocity of the falling sphere. Reproducibility of results is excellent and good agreement has been obtained using spheres of different diameters, vindicating the use of the revised wall‐correction factor. Results on a few typical glasses are discussed.
