Abstract: The $ bP$-component of a $ \left( {4n - 1} \right)$-dimensional homotopy sphere $ \Sigma \in {\theta _{4n - 1}} \cong b{P_{4n}} \oplus {\left( {{\text{Co}}\ker J} \right)_{4n - 1}}$ bounding a spin manifold $ M$ is shown to be computable in terms of the signature and the decomposable Pontrjagin numbers of $ M$.
