Report of Independent Auditors


To the Shareholders and Board of Trustees of
PaineWebber MidCap Fund

In planning and performing our audit of the financial 
statements of PaineWebber MidCap Fund for the period 
ended August 31, 1998, we considered its internal control, 
including control activities for safeguarding securities, in 
order to determine our auditing procedures for the purpose 
of expressing our opinion on the financial statements and to 
comply with the requirements of Form N-SAR, not to 
provide assurance on the internal control.

The management of PaineWebber MidCap Fund is 
responsible for establishing and maintaining internal 
control.  In fulfilling this responsibility, estimates and 
judgments by management are required to assess the 
expected benefits and related costs of controls.  Generally, 
controls that are relevant to an audit pertain to the entity's 
objective of preparing financial statements for external 
purposes that are fairly presented in conformity with 
generally accepted accounting principles.  Those controls 
include the safeguarding of assets against unauthorized 
acquisition, use or disposition.

Because of inherent limitations in internal control, errors or 
fraud may occur and not be detected.  Also, projection of 
any evaluation of internal control to future periods is 
subject to the risk that it may become inadequate because 
of changes in conditions or that the effectiveness of the 
design and operation may deteriorate.

Our consideration of the internal control would not 
necessarily disclose all matters in the internal control that 
might be material weaknesses under standards established 
by the American Institute of Certified Public Accountants.  
A material weakness is a condition in which the design or 
operation of one or more of the internal control components 
does not reduce to a relatively low level the risk that errors 
or fraud in amounts that would be material in relation to the 
financial statements being audited may occur and not be 
detected within a timely period by employees in the normal 
course of performing their assigned functions.  However, 
we noted no matters involving the internal control and its 
operation, including controls for safeguarding securities, 
that we consider to be material weaknesses as defined 
above at August 31, 1998.

This report is intended solely for the information and use of 
the board of trustees and management of PaineWebber 
MidCap Fund and the Securities and Exchange 
Commission.
