  We report a Far Ultraviolet Spectroscopic Explorer satellite observation of
the supernova remnant N49 in the Large Magellanic Cloud, covering the 905 --
1187 A spectral region. A 30'' square aperture was used, resulting in a
velocity resolution of ~100 km/s. The purpose of the observation was to examine
several bright emission lines expected from earlier work and to demonstrate
diffuse source sensitivity by searching for faint lines never seen previously
in extragalactic supernova remnant UV spectra. Both goals were accomplished.
Strong emission lines of O VI 1031.9 A, 1037.6 A and C III 977.0 A were seen,
Doppler broadened to +/- 225 km/s and with centroids red-shifted to 350 km/s,
consistent with the LMC. Superimposed on the emission lines are absorptions by
C III and O VI 1031.9 at +260 km/s, which are attributed to warm and hot gas
(respectively) in the LMC. The O VI 1037.6 A line is more severely affected by
overlying interstellar and H2 absorption from both the LMC and our galaxy. N
III 989.8 A is not seen, but models indicate overlying absorption severely
attenuates this line. A number of faint lines from hot gas have also been
detected, many of which have never been seen in an extragalactic supernova
remnant spectrum.
