  The authors of the title paper (Optik, 125 (2014) 1825-1828) claim to have
synthesized a new nonlinear optical (NLO) gamma bis glycinium oxalate (GBGOx)
crystal by slow evaporation solution technique. In this communication, many
points of criticism, concerning the characterization of this so called GBGOx
NLO crystal are highlighted to prove that the title paper is completely
erroneous.
