     In the earth sciences, the prospecting for, and exploration of, energy resources (e.g. crude oil, oil sand, oil shale, coal, bitumina), as well as the mining and quality control of such resources, has concerned mineralogists, geologists and geochemists for centuries, including the specialists of thermal analysis among them [405–421].

     Consequently, the Exchequer reconsidered its earlier decision and announced its new policy in October 1835: all bitumina, including those in liquid form, were to be subject to the Imperial Mining Prerogative and thus fell under imperial jurisdiction. Privileges would be distributed by the Ministry of Finance, as they were to Josef Micewski in 1838 and the Drohobycz Chamber of Commerce in 1841.²³ In 1840, the Exchequer announced that a mining tithe of 10 percent would be collected on all bitumina, and that, in general, possessors of land containing bitumina would be treated according to the same mining laws that applied to other enfeoffable minerals. But this soon changed. The Exchequer responded to local pressure in December 1841 by again removing liquid bitumina that did not appear in conjunction with coal or solid bitumina from the Imperial Mining Prerogative.²⁴
