                             RULE 12B-25(b) AND(c)

     If the subject report could not be filed without unreasonable effort or
expense and the registrant seeks relief pursuant to Rule 12b-25(b), the
following should be completed. (Check appropriate box.)

[X]  (a) The reasons described in reasonable detail in Part III of this form
     could not be eliminated without unreasonable effort or expense;

[X]  (b) The subject annual report, semi-annual report, transition report on
     Form 10-K, 20-F, 11-K or Form N-SAR, or portion thereof will be filed on or
     before the 15th calendar day following the prescribed due date; or the

                                    NARRATIVE

     State below in reasonable detail the reasons why Form 10-K, 11-K, 20-F,
10-Q, N-SAR or the transition report portion thereof could not be filed within
the prescribed time period. (Attach extra sheets if needed.)

     Ferrofluidics Corporation (the "Company") is unable to meet its filing date
for the Form 10-K for the year ended June 27, 1998 without unreasonable effort
or expense. The Company has requested further advice from its accountants and
legal counsel regarding accounting and legal disclosure matters as a result of
the consummation of the sale of certain of the assets of its Systems Division on
September 23, 1998. Due to these circumstances, the Company is requesting an
extension on this Form 12b-25 of the Securities Exchange Act of 1934, as
amended.

                                     PART IV
                                OTHER INFORMATION

     (1) Name and telephone number of person to contact in regard to this
notification:

         WILLIAM B. FORD, VICE PRESIDENT AND CHIEF FINANCIAL OFFICER, 
         (603) 883-9800

     (2) Have all other periodic reports required under Section 13 or 14(d) of
the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act
of 1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If the answer is no,
identify report(s).

                                                                [X] Yes   [ ] No

     (3) Is it anticipated that any significant change in results of operations
from the corresponding period for the last fiscal year will be reflected by the
earnings statements to be included in the subject report or portion thereof?

                                                                [X] Yes   [ ] No



                                        2


   3



     If so: attach an explanation of the anticipated change, both narratively
and quantitatively, and, if appropriate, state the reasons why a reasonable
estimate of the results cannot be made.

     The Company believes that there will be a significant change in results of
operations from the corresponding period for the last fiscal year as reflected
in the earnings statement to be included in the Form 10-K for the year ended
June 27, 1998. However, the Company cannot reasonably estimate such change until
the Company completes its consultation with its accountants and legal counsel
referred to in Part III above.
