                 Emergency Medical Services Corporation
                 Amendment No. 3 to Registration Statement on Form S-1
                 (File No. 333-127115)
                 -----------------------------------------------------

Dear Mr. Zimmerman,

                  In light of our conversation Tuesday morning, in which you
raised certain questions about the terms of the EMS L.P. amended and restated
limited partnership agreement, we concluded that you would consider it
appropriate to include a description of that agreement in the prospectus for the
class A common stock to be issued in exchange for the EMS L.P. class B units --
notwithstanding the fact that the class B unit holders are making no investment
decision.

                  Accordingly, we intend to add to the second prospectus
included in the registration statement, under the caption "Description of
Capital Stock", a new section titled "Partnership Agreement". A copy of the text
of that section is enclosed for your information.

                  Thank you for your continuing assistance. Please contact the
undersigned at (212) 836-8685 or Marybeth O'Keefe at (212) 836-8456 with any
further comments or questions you may have.


                                   Sincerely,

                                   /s/  Lynn Toby Fisher

                                        Lynn Toby Fisher

Encl.

PARTNERSHIP AGREEMENT

MANAGEMENT

    EMS L.P. is organized as a Delaware limited partnership and will be
governed by the terms of the partnership agreement.  The partnership agreement
generally provides that we, as sole general partner of the partnership, will
have sole and exclusive responsibility for the management of the business and
affairs of the partnership.  No limited partner may take part in the operation,
management or control of the business of the partnership by virtue of being a
holder of LP exchangeable units.  Certain restrictions apply to our ability to
engage in certain mergers and similar transactions.  See "-- LP Exchangeable
Units and Class B Special Voting Stock."

    The limited partners of EMS L.P. have agreed that, in the event of any
conflict in the fiduciary duties owed by us to our stockholders and by us, as
general partner of the partnership, to such limited partners, we may act in the
best interests of our stockholders without violating fiduciary duties to such
limited partners or being liable for any resulting breach of our duties to the
limited partners.

    The partnership agreement does not restrict our business activities and does
not require that we conduct all of our business through EMS L.P.

TRANSFERABLITY OF INTEREST

    The partnership agreement provides that we may not voluntarily withdraw from
the partnership, or transfer or assign our interest in the partnership, except
to an affiliate or, in connection with a merger or similar transaction, to a
successor.

    The LP exchangeable unit holders may transfer their interests in EMS L.P. to
another limited partner, an affiliate or a member of the Initial Investor
Group, as defined in our certificate of incorporation.  Any transferee must
agree to become a party to the partnership agreement as a limited partner.

ADDITIONAL CONTRIBUTIONS

    The partnership agreement provides that, in the event we issue additional
shares of capital stock, we will contribute to EMS L.P. as an additional
capital contribution any net proceeds from such issuance in exchange for
additional partnership interests with preferences and rights corresponding to
the capital stock we issue.

DISTRIBUTIONS

    The partnership agreement sets forth the manner in which distributions will
be made, so that we maintain the economic equivalency of the LP exchangeable
units and the class B common stock.  See "-- LP Exchangeable Units and Class B
Special Voting Stock."



LIMITED PARTNER EXCHANGE RIGHTS

    Pursuant to the partnership agreement, each LP exchangeable unit may be
exchanged for one share of class B common stock.  See "-- LP Exchangeable Units
and Class B Special Voting Stock."

AMENDMENTS OF THE PARTNERSHIP AGREEMENT

    Amendments to the partnership agreement may be proposed by us, as general
partner, or by partners holding at least 20% of the LP exchangeable units.

    Generally, the partnership agreement may be amended with our approval, as
general partner, and the holders of a majority of the LP exchangeable units.
Certain amendments that would, among other things, convert a limited partner's
interest into a general partner's interest, modify the limited liability of a
limited partner, alter the right to receive any distributions, or alter or
modify the provisions applicable to the LP exchangeable units must be approved
by each limited partner that would be adversely affected by the amendment.

EXCULPATION AND INDEMNIFICATION OF THE GENERAL PARTNER

    The partnership agreement generally provides that we, as general partner,
will incur no liability to EMS L.P. or any limited partner for losses sustained
or liabilities incurred as a result of errors in judgment or of any act or
omission if we carried out our duties in good faith.

    The partnership agreement also provides for our indemnification and
indemnification of our directors, officers, employees and agents from any loss,
liability, damage, cost or expense incurred by such person in connection with
our business or activities or those of EMS L.P., so long as the indemnitee is
not guilty of willful misconduct and was acting  in good faith within what the
indemnitee reasonably believed to be the scope of its authority for a purpose
which it reasonably believed to be not opposed to the interests of EMS L.P.

TAX MATTERS

    Pursuant to the partnership agreement, we will be the "tax matters partner"
of EMS L.P. and, as such, will have authority to make tax elections under the
Internal Revenue Code on behalf of the partnership.

TERM

    The partnership will continue in full force and effect until December __,
2095 or until sooner dissolved pursuant to the terms of the partnership
agreement.
