[Branches of natural science in the Halle Medical College program in the 18th and 19th centuries].

The subjects of natural sciences belonging in the 18th century to the complex of medicine in the early 19th century change over to the complex of reliability of the faculty of philosophy. The future physician passes a tentamen philosophicum. In the sixties of the 19th century the increase of knowledge in the field of natural sciences causes an increased consideration on these subjects for the basic medical training. On these conditions the tentamen philosophicum becomes the tentamen physicum, i.e. examination in natural sciences, the precursor of the preliminary medical examination of our time.
