for _m__{_x_}, _m__{_y_}, _m__{_z_}, -_i_(_e__{_x_}, _e__{_y_},
_e__{_z_}),
and F₂₃, F₃₁, F₁₂, F₁₄, F₂₄, F₃₄
for M_{_x_}, M_{_y_}, M_{_z_}, -_i_(E_{_x_}, E_{_y_}, E_{_z_})
lastly we shall have the relation _f__{k h} = - _f__{_h k_}, _F__{_k h_}
= -_F__{_h k_}, (the letter _f_, F shall denote the field, _s_ the
(_i.e._ current).
