This document has been scanned, and the images have been compiled into Adobe ACROBAT Portable Document Files. These PDF files require the user to install Acrobat Reader in order to view the files. The Acrobat Reader software is free and widely available. These files are created from single page images: a version converted to text has not been prepared at present. However, it should be possible for a resourceful user to cut and paste the graphics for each page, and to use them in an OCR program (including the full commercial version of Acrobat).
