Calcium was determined by permanganate titration of oxalic acid and confirmed by fame spectrophotometry, with the internal standard technique
ot Chow and Thompson (1955). Potassium was
determined by flame spectrophotometry at 766-mya
wavelength, and independently confirmed with estimation uf potassium by titration of the cobaltinitrite with potassium permanganate ( Hibbard and

general function of the system have been described
by Chakravarti and Joyner (1960).
In determining magnesium, an aliquot of the
ashed sample was dissolved in O.1N HCI and the
solution passed through a Dowex-30) N& 100-200
resin column of precalculated capacity. Intertering
anions were removed by elution with two-column
volumes of distilled water. The resin was then
