The early-type stars HD 164794, 164816, 164906 and 165052 belonging to the M8 nebula have been observed at high resolution using the IUE satellite. High velocity interstellar absorption components have been detected in each star's spectra at velocities of -32 and -53 km s-1. Such features must span across at least 8 pc in the nebula. A line profile fitting analysis has been carried out on all the UV interstellar lines to determine cloud component column densities and subsequently to determine the physical condition and chemical abundance of the associated interstellar gas. It is proposed that the stellar wind energy from the star HD 164794 (9 Sgr) may be sufficient to produce the high velocity gas motions.
