Report of Independent Registered Public Accounting Firm

To the Board of Directors
Dreyfus Premier Third Century Fund, Inc.

We have examined management's assertion, included
in the accompanying Management Statement Regarding
Compliance with Certain Provisions of the Investment
Company Act of      1940 that
Dreyfus Premier Third Century Fund, Inc.
(the "Company") complied with the requirements of
subsections (b) and (c) of Rule 17f-2 under the Investment
Company Act of 1940 ("the Act") as of July 31, 2007.
Management is responsible for the Company's compliance
with those requirements.  Our responsibility is to express an
opinion on management's assertion about the Company's
compliance based on our examination.

Our examination was made in accordance with the
standards of the Public Company Accounting
Oversight Board (United States) and, accordingly, included
examining, on a test basis, evidence about the Company's
compliance with those requirements and performing such
other procedures as we considered necessary in the
circumstances. Included among our procedures were the
following tests performed as of July 31, 2007,
and with respect to agreement of security and similar
investment purchases and sales, for the period from
June 30, 2007 (the date of our last examination)
through July 31, 2007;

Count and inspection of all securities and similar
investments located in the vault of Mellon Bank in New
York, without prior notice to management;

Confirmation of all securities and similar investments
held by institutions in book entry form (i.e., the Federal
Reserve Bank of Boston, the Depository Trust Company
and various sub-custodians);

Reconciliation of all such securities and investments to the
books and records of the Company and Mellon Bank;

Confirmation of all securities hypothecated, pledged, placed
in escrow, or out for transfer with brokers, pledges, transfer
agents or securities lending administrators;

Confirmation of all repurchase agreements, if any,
with brokers/banks and agreement of underlying
collateral with Mellon Bank's records or to documentation
of corresponding subsequent cash receipts;

Agreement of pending purchase activity as of
July 31, 2007 to documentation of subsequent
cash payments.

Agreement of Dreyfus Family of Funds' trade tickets for
5 security purchases and 5 security sales or maturities
for the period from June 30, 2007 through
July 31, 2007, to the books and records of the Funds
noting that they had been accurately recorded and
subsequently settled;

Review of Mellon Global Securities Services Report
on Controls Placed in Operation and Tests of Operating
Effectiveness ("SAS 70 Report") for the period from
January 1, 2006 through December 31, 2006 and noted
no negative findings were reported in the areas of Asset
Custody and Control.

We believe that our examination provides a reasonable
basis for our opinion. Our examination does not provide
a legal determination on the Company's compliance with
specified requirements.

In our opinion, management's assertion that
Dreyfus Premier Third Century Fund, Inc.
complied with the requirements of subsections (b) and (c) of
Rule 17f-2 of the Investment Company Act of 1940 as of
July 31, 2007 with respect to securities and similar
investments reflected in the investment account of the
Company is fairly stated, in all material respects.

management and the Board of Directors of
Dreyfus Premier Third Century Fund, Inc.
and the Securities and Exchange Commission and is not

these specified parties.
