I'm assuming it's Nelis,as in Winter pear,though the logic is as bizarre as any Mephisto. By the way,2d ends in a Y and not an Ebecause of the anagram,be warned.
Thank you,that was all I asking,to quote the first reply. Also to point out that 2 down was ALKALIMETRY and not ALKALIMETRE,in case not every body had got there because it is an anagram.
