»baculine
I still do not know the word "knouter", which I read in "The Most Dangerous Game" -- for the first time probably twenty or more years ago! -- but now suspect that it relates to the word "baculine", which relates to punishment by a rod or cane. This would make a knouter one who flogs or beats. I found baculine through the Omnificent English Dictionary In Limerick Form, which is on its way to presenting definintions of English words in limerick form. Delightful stuff.
