Abstract: M. Brown has shown that if $ f:{S^{n - 1}} \times I' \to {S^n}$, where $ I' = [ - 1,1]$, is an embedding, then the closure of either complementary domain of $ f({S^{n - 1}} \times 0)$ is homeomorphic to $ {B^n}$; in fact there is an embedding $ g : {B^n} \to {S^n}$ satisfying $ g\vert{S^{n - 1}} = f\vert{S^{n - 1}} \times 0$. This paper shows that the choice of embedding $ g$ can be made to be ``canonical,'' i.e. if $ f'$ is an embedding near $ f$ in the compact-open sense, then the embedding $ g'$ corresponding to $ f'$ is near $ g$.
