At low fields the deformation -- measured through linear birefringence -- scales quadratically with the capsule radius and with the magnetic field strength. These data confirm a long standing theoretical prediction (W. Helfrich, Phys. Lett. {\\bf 43A}, 409 (1973)), and permits the determination of the bending rigidity of the capsules as (2.6$\\pm$0.8)$\\times 10^{-21}$ J. At high fields, an enhanced rigidity is found which cannot be explained within the Helfrich model.
