Query: The Proton Spin Structure in Skyrme Type Models   It is demonstrated how in the soliton approach to baryons a small but
non-vanishing matrix element of the axial singlet current is obtained.
Furthermore it is shown that these models also provide a mechanism to
disentangle the ``matter" and ``glue" contributions to this matrix element.
Numerical results indeed exhibit a cancellation between these two components.
However, the magnitudes of both turn out to be significantly smaller than
unity.
