The de Haas-van Alphen effect has been measured in a single crystal of graphite between 3 and 85 kilogauss with the $c$ axis of the crystal parallel to the magnetic field. Two periods were observed: 2.05×${10}^{-5\mathrm{}}$ ${\mathrm{gauss}}^{-1\mathrm{}}$ for the electronic component and 1.53×${10}^{-5\mathrm{}}$ ${\mathrm{gauss}}^{-1\mathrm{}}$ for the holes. No new and unexpected oscillations were observed at magnetic fields as large as 100 kilogauss.
