Group III can be subdivided into two divisions without much injury to the delicacy of the individual tests.

[See document for Scheme of Analysis For Group III]
[See document for Diagramatic Scheme of Group III]

The successful division of this group has eliminated the possibility of certain metals oxidizing during their initial precipitation and washing.*
That the present of chromium precipitates an additional eleven per cent of zinc, but does not appreciably effect manganese.
