An illustration from an 1897 issue of The Idler magazine.  The caption reads: "From An Ultimate Dim Thule. (A Record of Dreams.) By S.H. Sime.  'I sat on the back of the Oonrouff-Wuff: he paused: sadness overcame him as he gazed fixedly into the fourth dimension and his tears dropped into the abyss.  Then another Brain-cell broke, and something else became me.'"
