 ``the space of all local relations that can be imposed on $\bc_0(X)$".
 Thus we say  a $1$-blob diagram consists of:
 \begin{itemize}
-\item An closed ball in $X$ (``blob") $B \sub X$.
+\item A closed ball in $X$ (``blob") $B \sub X$.
 \item A boundary condition $c \in \cF(\bdy B) = \cF(\bd(X \setmin B))$.
 \item A field $r \in \cF(X \setmin B; c)$.
 \item A local relation field $u \in U(B; c)$.
