A vacuum Curie balance was specially designed for the study of magnetic susceptibilities at higher temperatures. With this apparatus the magnetic study of sodium and potassium was made at different temperatures ranging from 32° to 250°C. Special attention has been paid to the preparation of the specimen. Corrections for all possible errors have been made. The results point out that the susceptibilities of the metals increase with temperature both below and above their melting points. The temperature coefficients of the susceptibility of valence electrons of the two metals are in general agreement with STONER’S theory.
