Summary: Re-examination of hodgkinsonite by optical and X-ray methods has shown the desirability of adopting a setting different from that selected by Palache and Schaller and by Rentzeperis. In the new arrangement the b and c axes are interchanged and the original negative end of the b-axis becomes positive. A table of angles for the common forms is given, also X-ray powder data and a space group determination.
