Dear Reader, At the time of scanning there were some pages that have text written by hand on the very edges of the page. For Example Image Number: 8,9,11,12,13,16,17,19,40,50. At the time of scanning it was observed in some pages of the book that Text is printed on the very edges as well as was miss printed. This is why we have left cropping on those pages. For Example Image Number: 18.
