EXHIBIT (5) & (23)




March 30, 1994


Merrill Lynch & Co., Inc.
World Financial Center
North Tower
New York, New York 10281-1220

Gentlemen:

As your counsel, we have examined a copy of the Restated Certificate of
Incorporation, as amended, of Merrill Lynch & Co., Inc. (hereinafter called the
"Company"), certified by the Secretary of State of the State of Delaware. We
are familiar with the corporate proceedings had in connection with the proposed
issuance and sale by the Company to the Underwriters named in the Terms
Agreement referred to below, pursuant to an Underwriting Agreement dated January
14, 1994 (the "Underwriting Agreement"), among the Company, Merrill Lynch & Co.,
Merrill Lynch, Pierce, Fenner & Smith Incorporated ("MLPF&S") and the other
firms named therein, as supplemented by the Terms Agreement dated March 15, 1994
(the "Terms Agreement") among the Company, MLPF&S, Dean Witter Reynolds Inc.,
Donaldson, Lufkin & Jenrette Securities Corporation, Kidder, Peabody & Co.
Incorporated, PaineWebber Incorporated, Prudential Securities Incorporated and

Salomon Brothers Inc, of $200,000,000 aggregate principal amount of the
Company's 6-3/8% Notes due March 30, 1999 (the "Notes"). We have also examined
a copy of the Indenture between the Company and Chemical Bank (successor by
merger to Manufacturers Hanover Trust Company), as Trustee, dated as of April 1,
1983, as amended and restated (the "Indenture"), and the Company's Registration
Statement on Form S-3 (File No. 33-51489) relating to the Notes (the
"Registration Statement").

Based upon the foregoing and upon such further investigation as we deemed
relevant in the premises, we are of the opinion that:

1. The Company has been duly incorporated under the laws of the State of
Delaware.

2. The Notes have been duly and validly authorized by the Company and when
the Notes have been duly executed and authenticated in accordance with the terms
of the Indenture and delivered against payment therefor as set forth in the
Underwriting Agreement, as supplemented by the Terms Agreement, the Notes will
constitute valid and legally binding obligations of the Company in accordance
with their terms, except to the extent that enforcement thereof may be limited
by bankruptcy, insolvency, reorganization or other laws relating to or affecting
enforcement of creditors' rights or by general equity principles.

2

We consent to the filing of this opinion as an exhibit to the Registration
Statement and as an exhibit to the Current Report of the Company on Form 8-K
dated March 30, 1994.
Very truly yours,

/s/ Brown & Wood
