Magnetic susceptibility and low-temperature specific-heat measurements have been made on several specimens of polycrystalline high-purity titanium, and in the case of the former measurement, on four single crystals. The calorimetric results are in good agreement with previously published data. A critically assessed average room-temperature susceptibility based on published magnetic susceptibility values [(3.17 \ifmmode\pm\else\textpm\fi{} 1)% \ensuremath{\mu}emu/g] is in good agreement with an average of the present results (3.17 \ifmmode\pm\else\textpm\fi{} ${0.01}_{5}$ \ensuremath{\mu}emu/g). The considerable scatter in the published data (3.0-3.36 \ensuremath{\mu}emu/g) is attributed, in part, to the influence of magnetic anisotropy and texture. The magnetic anisotropy of the best of the single crystals measured (${\ensuremath{\chi}}_{\ensuremath{\parallel}}\ensuremath{-}{\ensuremath{\chi}}_{\ensuremath{\perp}}=0.52$ \ensuremath{\mu}emu/g) is almost twice as large as that previously reported, and new results for the temperature dependences of ${\ensuremath{\chi}}_{\ensuremath{\parallel}}$ and ${\ensuremath{\chi}}_{\ensuremath{\perp}}$ in the range 80-400\ifmmode^\circ\else\textdegree\fi{}K are presented. The susceptibility at 0\ifmmode^\circ\else\textdegree\fi{}K is estimated to be approximately 2.9 \ensuremath{\mu}emu/g. Combining the calorimetric and magnetic results, and using an empirically derived electronic specific-heat enhancement factor, a value of 0.81 \ensuremath{\mu}emu/g was obtained for the spin paramagnetism ${\ensuremath{\chi}}_{s}$. Finally, assuming that ${〈{\ensuremath{\chi}}_{\mathrm{total}}〉}_{\mathrm{av}}\ensuremath{\cong}{\ensuremath{\chi}}_{s}+{\ensuremath{\chi}}_{\mathrm{orb}}$ (the orbital paramagnetism), we find the latter to be the dominant component of the susceptibility of titanium and equal to ${2.0}_{9}$ \ensuremath{\mu}emu/g.
