The plan came to nothing, and next year Becher was again busy at Vienna, trying to transmute Danube sand into gold, and writing his Theses chemicae veritatem transmutationis metallorum evincentes.
The views of Becher on the composition of substances mark little essential advance on those of the two preceding centuries, and the three elements or principles of salt, mercury and sulphur reappear as the vitrifiable, the mercurial and the combustible earths.

Georg Ernst Stahl, following in some measure the views held by Johann Joachim Becher, as, for instance, that all combustibles contain a " sulphur " (which notion is itself of older date than Becher's terra pinguis), regarded all substances as capable of resolution into two components,.
The phlogistonists endeavoured to introduce chemical notions to support it: Becher, in his Physica subterranea (1669), stated that mineral, vegetable and animal matter contained the same elements, but that more simple combinations prevailed in the mineral kingdom; while Stahl, in his Specimen Becherianum (1702), held the " earthy " principle to predominate in the mineral class, and the " aqueous " and " combustible " in the vegetable and animal classes.
The members of the council received the following amounts: Mr Drake, the governor, and Colonel Clive 280,000 rupees each; and Mr Becher, Mr Watts and Major Kilpatrick 240,000 rupees each.
Somewhat similar views were promoted by Becher, who named the principle acidum primogenium, and held that it was composed of the Paracelsian elements " earth " and "water."
