This m aterial was produced from a m icrofilm 'copy o f th e original d o cu m en t.While the m o st advanced technological means to photograph and reproduce th is docum ent have been used, th e quality is heavily d ependent upon the quality o f th e original subm itted.The following explanation of techniques is provided to help y o u understand markings or patterns which m ay appear on this reproduction.1.The sign or "ta rg et" for pages apparently lacking from th e docum ent photographed is "Missing Page(s)".If it was possible to o b tain th e missing page(s) o r section, th e y are spliced into the film along with adjacent pages.This m ay have necessitated cu ttin g thru an image and duplicating adjacent pages to insure you com plete continuity.2. When an image on th e film is obliterated w ith a large round black m ark, it is an indication th a t th e photographer suspected th at the copy may have moved during exposure and th u s cause a blurred image.Y ou will find a good image of the page in the adjacent fram e.3. When a m ap, draw ing or ch art, etc., was part of the m aterial being photographed th e photographer followed a definite m ethod in "sectioning" the m aterial.It is custom ary to begin photoing a t the upper left hand corner o f a large sheet and to continue photoing from left to right in equal sections with a small overlap.If necessary, sectioning is continued again -beginning below the first row and continuing on until com plete.4 .The m ajority of users indicate th a t the textual content is o f greatest value, however, a som ew hat higher quality reproduction could be made from "photographs" if essential to th e understanding of the dissertation.Silver prints o f "photographs" may be ordered a t additional charge by writing the O rder D epartm ent, giving th e catalog num ber, title , author and specific pages you wish reproduced.
