Evidence that the nebular emission of V 1016 Cyg originates from at least two emission regions of widely different particle densities is derived from IUE spectra. It is suggested that a hot (200,000K) stellar source provides the ionizing radiation for a low density, Ne = 1 million/cucm, nebula. This nebula has a radius of 7 times 10 to the 15th power cm and electron temperature between 10,000 and 20,000K, containing 0.01M. The collisionally ionized high density cloud may contain a mass as low as 10 to the minus 9 M, located in the outer part of the Mira wind, at the point of collision of two stellar winds, a Mira wind and a wind from a hot star.
