Using a new type of concentric cylinder viscosimeter, the viscosity, 7, and electrical resistivity, κ of some commercial glasses and the glasses of the soda‐silicate system have been investigated in the region of 700 to 1400 °C corresponding from 3 to 10 2 poises and from 0.3 to 10 3 ohms. The results in the viscous region show proportionality between log η and log κ in the region investigated. In the two glasses investigated at lower temperatures, it can be seen that the same constants do not hold thronghout the whole region. These results are discussed considering the kinetic picture of liquids (see summary).
