The Eridanus superbubble has been called ``the Rosetta Stone" of superbubbles because virtually all of the processes which shape the interstellar medium are taking place somewhere within its boundaries. One of the features of this region is the Eridanus Soft X-ray enhancement - a region of hot (> 3 million K) gas that fills the Eridanus cavity. To investigate the physical properties of 105.5K gas within the superbubble, a Far Ultraviolet Spectroscopic Explorer (FUSE) satellite observation of OVI emission has been obtained and will be compared with an archival OVI absorption measurement along a nearby sightline. An additional OVI emission measurement towards an adjacent optically thick cloud is planned in order to isolate the location of the OVI emission within the cavity. Preliminary results will be presented, based on the data already obtained.
