This works, but now I am encountering a different problem.  I am 
including scans of pages in my introduction using

   \usepackage{graphicx}

in the preamble and

   \includegraphics{mss_scans/R2_f9v.jpg}

in the body of the text.  However, with this new line added, I get an 
error message when the compiler reaches the graphics.  Is there a way 
that I can have both postscript and scanned images in the document?

Sincerely,
Toke
