Abstract : The concept of 'Target Mass' and 'Effective Target Mass' is discussed. Evidence is presented which questions the validity of attempting to relate the 'Effective Target Mass' to the concept of a virtual pion surrounding the nucleon. Relations between the 4-momentum transfer, the quantity (E - P cos theta) of the recoil nucleon and the 'Effective Target Mass' are derived which show in conjunction with experimental data that the 'Effective Target Mass' of the order of a pion mass occurs accidentally.
