Pollen grains of Apiaceae from the profile at Błędowo, Mazovia region, Central Poland were identified. Pollen of this family occurs in higher frequencies in the Late Glacial, the beginning of the Holocene and in the periods under strong human influence. Transfer of pollen of Apiaceae from plants to lake deposits is different for particular species and depends rather on insect activity during the season as well as on the activity of their predators and/or the oscillation of animal populations than the selectivity in insect feeding. Different environmental conditions around the sites, which result in various patterns of transfer agents can cause some difficulties in interpretation of vegetational changes inferred from pollen data.

The article is the first attempt to analyze comprehensively Polish numismatic illustration in the 19th century created in noble graphic techniques: woodcut, copperplate, etching and steelwork. The authors focused on discussing drawings from the work of J. Ch. Albertandi “History of Polish medals attested and explained” that never appeared in print and the works of K. W. Kielisiński, A. Oleszczynski and J. Lelewel. They drew attention to the value of the iconographic material as the transmission of scientific information complementary to the text, the graphic engraving as an independent, sometimes outstanding work of art and the complexity of motives and inspirations that guided artists in the subject of Polish coins and medals.
