INFORMATION TO USERS
This was produced from a copy of a document sent to us for microfilming. While the
most advanced technological means to photograph and reproduce this document
have been used, the quality is heavily dependent upon the quality of the material
submitted.
The following explanation of techniques is provided to help you understand
markings or notations which may appear on this reproduction.
1. The sign or "target" for pages apparently lacking from the document
photographed is "Missing Page(s)". If it was possible to obtain the missing
page(s) or section, they are spliced into the film along with adjacent pages.
This may have necessitated cutting through an image and duplicating
adjacent pages to assure you of complete continuity.
2. When an image on the film is obliterated with a round black mark it is an
indication that the film inspector noticed either blurred copy because of
movement during exposure, or duplicate copy. Unless we meant to delete
copyrighted materials that should not have been filmed, you will find a good
image of the page in the adjacent frame. If copyrighted materials were
deleted you will find a target note listing the pages in the adjacent frame.
3. When a map, drawing or chart, etc., is part of the material being photo­
graphed the photographer has followed a definite method in "sectioning"
the material. It is customary to begin filming at the upper left hand corner of
a large sheet and to continue from left to right in equal sections with small
overlaps. If necessary, sectioning is continued again—beginning below the
first row and continuing on until complete.
4. For any illustrations that cannot be reproduced satisfactorily by xerography,
photographic prints can be purchased at additional cost and tipped into your
xerographic copy. Requests can be made to our Dissertations Customer
Services Department.
5. Some pages in any document may have indistinct print. In all cases we have
filmed the best available copy.
