                                      [10]


                  NOTES TO FINANCIAL STATEMENTS -- (unaudited)

      1. Significant  Accounting Policies -- The Corporation is registered under
the Investment Company Act of 1940, as amended, as a non-diversified, closed-end
management  investment  company.  The following is a summary of the  significant
accounting policies  consistently followed by the Corporation in the preparation
of its  financial  statements.  The policies are in conformity  with  accounting
principles generally accepted in the United States of America.

      Security  Valuation -- Securities are valued at the last sale price or, if
         unavailable,  at the closing bid price.  Corporate  discount  notes are
         valued at amortized cost, which approximates  market value.  Securities
         for which no ready market exists,  including The Plymouth Rock Company,
         Inc.  Class A Common Stock,  are valued at estimated  fair value by the
         Board of Directors.

      Federal  Income  Taxes  -- It is the  Corporation's  policy  to  meet  the
         requirements  of the  Internal  Revenue  Code  applicable  to regulated
         investment companies and to distribute all of its taxable income to its
         stockholders. Therefore, no Federal income taxes have been accrued.

      Use of  Estimates  -- The  preparation  of  the  financial  statements  in
         accordance with accounting  principles generally accepted in the United
         States of America requires management to make estimates and assumptions
         that affect the amounts  reported.  Actual  results  could  differ from
         those estimates.

      Other  --  Security  transactions  are  accounted  for  on  the  date  the
         securities  are  purchased  or  sold,  and cost of  securities  sold is
         determined   by   specific   identification.    Dividend   income   and
         distributions to stockholders are recorded on the ex-dividend date.

      2. Common Stock -- The Corporation repurchased 56,300 shares of its Common
Stock in the first six months of 2005 at an  average  price of $23.28 per share,
representing  an average  discount  from net asset value of 14.34%.  It may from
time to time  purchase  Common  Stock in such  amounts and at such prices as the
Board of Directors may deem advisable in the best interests of the stockholders.
Purchases  will  only be made at less than net asset  value per  share,  thereby
increasing  the net asset  value of shares held by the  remaining  stockholders.
Shares  so  acquired  may be held as  treasury  stock,  used in  optional  stock
distributions, or retired.

      3. Investment  Transactions -- The aggregate cost of securities  purchased
and the aggregate  proceeds of securities  sold during the six months ended June
30, 2005 (excluding short-term  investments),  were $49,000,916 and $62,870,467,
respectively.

      As of June 30, 2005,  based on cost for Federal  income tax purposes,  the
aggregate gross unrealized appreciation and depreciation for all securities were
$299,712,369 and $22,462,296, respectively.

      4. Operating  Expenses -- The aggregate  remuneration  paid during the six
months ended June 30, 2005 to officers and  directors  amounted to $600,250,  of
which $52,750 was paid as fees to directors  who were not officers.  Benefits to
employees are provided through a profit sharing  retirement plan.  Contributions
to the plan are  made at the  discretion  of the  Board of  Directors,  and each
participant's benefits vest after three years. No contributions were made to the
plan for the six months ended June 30, 2005.

             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF
   CENTRAL SECURITIES CORPORATION

      We have  reviewed the  accompanying  statement of assets and  liabilities,
including the statement of investments,  of Central Securities Corporation as of
June 30, 2005, and the related  statements of operations,  changes in net assets
and financial  highlights  for the six-month  period ended June 30, 2005.  These
financial  statements  are  the  responsibility  of the  management  of  Central
Securities Corporation.

      We have conducted our review in accordance  with standards  established by
the Public  Company  Accounting  Oversight  Board (United  States).  A review of
interim  financial  information  consists  principally  of  applying  analytical
procedures  and  making  inquiries  of persons  responsible  for  financial  and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with the standards of the Public Company  Accounting  Oversight Board
(United  States),  the  objective  of  which  is the  expression  of an  opinion
regarding  the financial  statements  taken as a whole.  Accordingly,  we do not
express such an opinion.

      Based on our review, we are not aware of any material  modifications  that
should be made to the financial  statements  referred to above for them to be in
conformity with U.S. generally accepted accounting principles.

      We have previously  audited,  in accordance with standards  established by
the Public Company Accounting  Oversight Board (United States), the statement of
changes in net  assets  for the year ended  December  31,  2004,  and  financial
highlights for each of the five years in the period ended December 31, 2004, and
in our report  dated  January 26, 2005 we expressed  an  unqualified  opinion on
those financial statements.
