 \subsection{The $n{+}1$-category of sphere modules}
 
-
+In this subsection we define an $n{+}1$-category of ``sphere modules" whose objects
+correspond to $n$-categories.
+This is a version of the familiar algebras-bimodules-intertwinors 2-category.
+(Terminology: It is clearly appropriate to call an $S^0$ modules a bimodule,
+since a 0-sphere has an obvious bi-ness.
+This is much less true for higher dimensional spheres, 
+so we prefer the term ``sphere module" for the general case.)
