[texhax] environment with smaller typeface and narrower margins

[Jonathan Myles]

Is there a way of defining an environment, {query} say,
so that I can write

%%%%%%%%%%%%%
Bloggs et al explain that.....

\begin{query}
 is my understanding of this correct? Can we improve it by....
\end{query}


They then go on ....

%%%%%%%%%

and my query will come out in a different typeface with narrower margins? 

thanks

Jonathan
