    We propose 40~Ks. ASCA spectroscopic observations of the S0 galaxy   
    NGC~4382.  This galaxy is one of the early-type galaxies detected w/ 
    the lowest X-ray to optical flux ratio, and has a peculiar           
    X-ray spectrum, with a significant excess of counts in the lowest    
    spectral channels, by comparison with similar {\it Einstein} & ROSAT 
    spectra of X-ray bright E and S0 galaxies.  ASCA observations will   
    result in unprecedented high quality X-ray spectra, which will allow 
    us to constrain the nature of the emission components and in         
    particular to explore the possible presence of a hot ISM. With these 
    data we will be able to constrain theoretical scenarios for the X-ray
    emission, and to understand how different X-ray brightness may be    
   related to different structura
