************************************************************************* 51190 Hard X-ray characteristics of Narrow Emission Line Galaxies (NELGs) are difficult to be understood in the current unified Seyfert scheme. In order to elucidate the nature of NELGs, we need to observe the brightest NELG NGC5506. In addition, recent soft X-ray observations have shown that relatively distant NELGs are important contributers to the soft X-ray background. We propose to observe a NELG belonging to this population, which was discovered by the Einstein EMSS. *************************************************************************
