Measurements have been made in the liquid helium temperature region of the magnetic threshold curve of rhenium by observations of the magnetic moment of a powdered sample. The transition temperature ${T}_{c}$ in zero magnetic field was found to be 2.42\ifmmode^\circ\else\textdegree\fi{}K, and the observed slope of the threshold curve at $T={T}_{c}$ was 235 gauss per degree. Assuming a reversible transition, the value of the normal electronic specific heat coefficient $\ensuremath{\gamma}$ obtained from the magnetic data is 4.6\ifmmode\times\else\texttimes\fi{}${101}^{\ensuremath{-}4}$ calories per mole per ${\mathrm{degree}}^{2}$, a value which would be expected from the correlation between $\frac{\ensuremath{\gamma}}{V}$ and ${T}_{c}$ previously proposed.
