John Patterson Smith - father of Clara Elvira Smith Wright

After reading again the autobiography of Harry Wright, he mentions donating the diary of John Pattesron Smith, his maternal grandfather, to Miami University.  I am trying to locate it just to look and maybe make some copies of pages.  But found the below on web.
