At the same time, however, in studying natural bodies, primary attention has not been paid to their total character; the body either ceased to be an individual, as in the case of mathematical methods, or has become a complex of separate, not always closely connected characteristics examined by laboratory analyses. The goniometric study of a crystal, for example, has developed into the determination of constants of the crystal lattice, but the examination of minerals from a specific deposit was concerned primarily with the chemical analysis of their admixtures. In geological sciences a thorough morphological investigation has preserved its original importance, particularly in geomorphology and paleontology. Even in petrography, the three-dimensional description of rocks was replaced by the study of thin sections, since the optical microscope does not permit examination of an uneven surface as a result of a restricted depth of observation field.
