The metal content of GR 8 and Sextans B
Ionic abundances for two irregular dwarf galaxies belonging to the Local Group, GR 8 and Sextans B, are presented. The oxygen abundances have been found to be 0.055 solar masses and 0.16 solar mass, respectively. The Ne(2+)/O(2+) abundance ratio is within the range of what is observed for other irregular galaxies but the N(+)/O(+) and the S(+)/O(+)
