The 371 mu MgOH line rather than the Mg resonance line at 280.2 :nu was used, because the latter is straddled by strong OH lines. After a study of the infiucr.ee of possible disturbances (AliOj and reiOi), standard solutions were prepared and used to establish a con- -- centration vs. intensity calibration. This was independently compared with spcctrophotnmetric resuits after a Ca-Mg sep aration via ion exchange. The results of the methods showed goi agreement. The fiame-pnotnmetric method is suitable for b samples containing less than l'",' MgO. 7 figs., 1 tabic. 3 refs. X.W.J.F. Device for cleaving crystals. M. L. Volpc and C. E. Paschaii. Rre. Sci.
