Independent Accountants' Report
To the Board of Directors of
Merrill Lynch Index Funds, Inc.:
We have examined the investment accounts shown
by the books and records of Merrill Lynch S&P 500
Index Fund, Merrill Lynch SmallCap Index Fund and
Merrill Lynch Aggregate Bond Index Fund
(collectively the "Funds")of the Merrill Lynch
Index Funds, Inc. (the "Corportion") for the
period from the date of our last similar examination
on October 31, 1997, to December 31, 1997. It is
understood that this report is solely for the use
of management and the Securities and Exchange
Commission and should not be used for any other
purpose.
Securities owned as of the close of business on
December 31, 1997, all of which are in book entry
form and shown by the books and records audited
by us, were confirmed with Depository Trust Company,
New York, New York; Participant Trust Company, New
York, New York; and Chase Manhattan Bank, New York,
New York. We confirmed all securities out on loan
on that date with the applicable brokers. For
unsettled trades, we performed other auditing
procedures.
Because the above procedures do not constitute an
audit in accordance with generally accepted auditing
standards, we do not express an opinion on the
investment accounts referred to above. In connection
with the procedures referred to above no matters
came to our attention that caused us to believe that
the specified accounts should be adjusted. Had we
performed additional procedures or had we audited
the financial statements in accordance with generally
accepted auditing standards, matters might have
come to our attention that would have been reported
to you. This report relates only to the investments
specified above and does not extned to any financial
statements of the Funds taken as a whole.
