        Discussion of the experimental data relevant to the establishment of the equation of state of a magnetic substance.  The following topics, in particular, are discussed:  (1) Magnetization of Ni as a function of field and temperature in the range 20°-630°; (2) reversible temperature variations in relation to specific heat; (3) determinations of spontaneous magnetization; (4) the impossibility of ferromagnetic equation of state.  Interpretations of experimental data recently obtained (abs. 3638) given.
