 Let $R_*$ be the chain complex with a generating 0-chain for each non-negative
 integer and a generating 1-chain connecting each adjacent pair $(j, j+1)$.
+(So $R_*$ is a simplicial version of the non-negative reals.)
 Denote the 0-chains by $j$ (for $j$ a non-negative integer) and the 1-chain connecting $j$ and $j+1$
 by $\iota_j$.
 Define a map (homotopy equivalence)

+Next we show that the action maps are compatible with gluing.
+Let $G^m_*$ and $\ol{G}^m_*$ be the complexes, as above, used for defining
+the action maps $e_{X\sgl}$ and $e_X$.
+The gluing map $X\sgl\to X$ induces a map

+and it is easy to see that $\gl(G^m_*)\sub \ol{G}^m_*$.
+From this it follows that the diagram in the statement of Proposition \ref{CHprop} commutes.

 Main idea is that for all $i$ there exists sufficiently large $k$ such that
 $\hat{N}_{k,l} \sub N_{i,l}$, and similarly with the roles of $N$ and $\hat{N}$ reversed.
