The percentage of sulphur corresponding to the "K2O" and Mg
analyses, if they _are_ both there as sulphates, is indeed 22%, so it looks
as if they are both there as sulphates. The amount of oxygen in the sulphates
would be 44%, so the K (18%), S, Mg and O would add up to 95%, implying
that there is little water of crystallysation in the MgSO4.
