   We are making a survey of the low energy emission line properties of
   LMXRB. This proposal is to complete this survey by observing the last
   two suitable low absorption systems 4U 1755-33 and LMC X-2. The survey
   to date is showing different line patterns that may be related to the
   abundance and evolutionary status of the companion star. By increasing
   the size of the sample we will be able to investigate the importance of
   abundance variations, vs. differences in the ionization state and
   system geometry.
