 In \S \ref{ssec:spherecat} we explain how $n$-categories can be viewed as objects in an $n{+}1$-category 
 of sphere modules.
-When $n=1$ this just the familiar 2-category of 1-categories, bimodules and intertwinors.

 In \S \ref{ss:ncat_fields}  we explain how to construct a system of fields from a disk-like $n$-category 
 (using a colimit along certain decompositions of a manifold into balls).
