The following typographical errors in the article by Dr. Fadhil At Chalabi, the Deputy Secretary General of OPEC, carried in last week's MEES (28 September 1987), should be noted:

- Page D1, paragraph 2, line 9: for "$6-9/B" read "$7-9/B" - Page D2, paragraph 3, line 12: for 1989 read 1990

- Page D4, paragraph 5, lines 1-2: the sentence "past experience has shown that at a price above $18/B oil cannot be considered as competitive with coal"...
