        (SELECTED) NOTES TO FINANCIAL STATEMENTS (Unaudited)
--------------------------------------------------------------------------------

Petroleum  &  Resources  Corporation  (the  Corporation)  is
registered under the Investment Company Act of 1940 as a non-
diversified investment company. The Corporation's investment
objectives  as well as the nature and risk of its investment
transactions are set forth in the Corporation's registration
statement.

Security  Valuation-Investments  in  securities  traded   on
national  security exchanges are valued at the last reported
sale  price  on  the day of valuation. Over-the-counter  and
listed  securities for which a sale price is  not  available
are   valued  at  the  last  quoted  bid  price.  Short-term
investments  (excluding  purchased options)  are  valued  at
amortized cost. Purchased and written options are valued  at
the last quoted asked price.


Item 2.  CONTROLS AND PROCEDURES.

Conclusions  of principal officers concerning  controls  and
procedures:

(a)  As  of May 25, 2005, an evaluation was performed  under
the  supervision and with the participation of the  officers
of  Petroleum  &  Resources Corporation  (the  Corporation),
including   the  principal  executive  officer   (PEO)   and
principal financial officer ("PFO"), of the effectiveness of
the  Corporation's disclosure controls and procedures. Based
on  that  evaluation, the Corporation's officers,  including
the  PEO  and PFO, concluded that, as of May 25,  2005,  the
Corporation's   disclosure  controls  and  procedures   were
reasonably  designed so as to ensure: (1)  that  information
required to be disclosed by the Corporation on Form  N-Q  is
recorded, processed, summarized and reported within the time
periods  specified by the rules and forms of the  Securities
and  Exchange Commission; and (2) that material  information
relating to the Corporation is made known to the PEO and PFO
as  appropriate to allow timely decisions regarding required
disclosure.

(b)    There  have  been  no  significant  changes  in   the
Corporation's internal control over financial reporting  (as
defined  in Rule 30 a-3(d) under the Investment Company  Act
of  1940  (17  CFR  270.30a-3(d)) that occurred  during  the
Corporation's  last  fiscal  quarter  that  has   materially
affected, or is reasonably likely to materially affect,  the
Corporation's internal control over financial reporting.


Item 3.  EXHIBITS.

The  certifications of the principal executive  officer  and
principal financial officer pursuant to Rule 30 a-2(a) under
