Re: Registration Statement on Form S-3
    Dresser Industries, Inc.

Gentlemen:


Reference is made to the Registration Statement on Form S-3, as amended or 
supplemented (the "Registration Statement"), filed with the Securities and 
Exchange Commission under the Securities Act of 1933, as amended (the "Act"), 
with respect to the contemplated issuance by Dresser Industries, Inc. (the 
"Company") from time to time of up to $400,000,000 of Debt Securities (the 
"Debt Securities"). The Debt Securities are to be issued pursuant to an 
Indenture dated as of April 18, 1996 (as amended or supplemented, the 
"Indenture") between the Company and Texas Commerce Bank National Association 
as Trustee. As Corporate Counsel of the Company, I have examined such 
corporate records, certificates and other documents and questions of law as 
I deem necessary or appropriate to this opinion.

Based on the foregoing, I am of the opinion that:

  (a)  The Company has been duly incorporated and is validly existing in good 
       standing under the laws of the State of Delaware; and

  (b)  The Indenture is, and the Debt Securities, when duly authorized, 
       authenticated and delivered in accordance with the terms of the 
       Indenture, will be, valid and binding obligations of the Company, 
       enforceable against the Company in accordance with their respective 
       terms, except as enforceability may be limited by bankruptcy, insolvency,
       fraudulent conveyance or transfer, reorganization, moratorium or other 
       laws relating to or affecting creditors' rights generally and by general
       principles of equity (regardless of whether such enforceability is 
       considered in a proceeding in equity or at law).

I hereby consent to the filing of this opinion as Exhibit 5 to said 
Registration Statement and to the use of my name under the caption "Legal 
Matters" in the Prospectus contained therein.

                                          Very truly yours,



                                           /s/  Rebecca R. Morris
