     File No. 333-52157
 
     Dear Sir or Madam:
 
     In accordance with the provisions of Rule 497(j) of Regulation C under the
     Securities Act of 1933 (the "Securities Act"), this letter serves to
     certify that the most recent amendment to the Registration Statement on
     Form S-6 (the "Registration Statement") of the above-referenced Series does
     not differ from that which would have been filed pursuant to Rule 487(b) of
     the Securities Act. Amendment No. 1, which was the most recent amendment to
     the Registration Statement, was filed electronically with the Commission on
     May 19, 1998.
 
     Very truly yours,
 
     JOHN NUVEEN & CO., INCORPORATED
 
     Gifford R. Zimmerman
    Vice President
