Hafid: If I remember correctly Nabokov said that his intention was  that there should be no dot after 'northern land' in the last entry of the index - an indication of the suicide Kinbote has been contemplatinge before in his despair en commentary ('Dear Jesus, help me!'). I dont't remember, however, whether he said this in an interview or whether Boyd mentions it in his biography..PS The Library of America edition of PF, edited by Dmitri Nabokov and Boyd, does have a dot, though. 

 

JM: Ex Ponto – Zembla, northern land… ponto=dot   

 

Btw: Would Nabokov have been thrilled by the first and last syllables in the word “IN-d-EX”?
