During many years of scientific activity, Józef Łepkowski (1826-1894), archaeologist, the first Polish professor of this discipline and protector of monuments, looked after the collections belonging to the Krakow Scientific Society (the predecessor of the Academy of Arts and Sciences), the
Jagiellonian University, and the Czartoryski dukes for whom he acquired the collection items. The archaeological artifacts, works of art, works of artistic craftsmanship, collections of weapons, and other artifacts obtained by him constitute a valuable part of the resources of Krakow institutions to this day. The article shows the methods by which, in the 19th century, objects were acquired for state institutions, scientific societies and large, aristocratic collections. The author takes as an example the fate of the collections of Karol Rogawski (1820-1888) and Bolesław Podczaszyński (1822-1876). Encouraged by Łepkowski, Rogawski donated the book collection, archaeological artifacts, and works of art and crafts to the Jagiellonian University and the Czartoryski dukes. However, a specialized part of Podczaszyński’s collection - archaeological artifacts with notes on prehistoric finds from the territory of the former Polish-Lithuanian Commonwealth - was purchased by the Academy of Arts and Sciences as a result of Łepkowski’s efforts. Therefore, thanks to the long and complicated measures taken by this tireless researcher, museum expert, and protector of monuments, the collections survived in their entirety to the present day, avoiding the dispersion to which many other private 19th-century collections were subjected.

Earthworms can be used in the vermicomposting process. The success of the process depends on many factors, including the choice of the appropriate earthworm species. Eisenia fetida and Dendrobaena veneta are treated as "compost earthworms". They are characterized by a relatively short life
cycle, relatively fast growth rate, efficient reproduction and a similar amount of organic matter processed, compared to species found in the natural environment. However, while analyzing their features in more detail, it can be seen that these two species differ. The aim of this study was to compare the selected features of the Eisenia fetida (Sav.) and Dendrobaena veneta (Rosa) earthworm populations in an annual cycle. The mature specimens of E. fetida or D. veneta were put in groups into plastic boxes with soil. Populations were checked regularly by manual sorting of the medium. The earthworms and cocoons were cleaned, counted and weighed individually. Afterwards, the mature individuals were placed in appropriate containers, while the cocoons were separated from the starting populations. The earthworms were fed ad libidum on kitchen wastes every four weeks. The experiment was carried out under constant laboratory conditions for 52 weeks. The analysis of the studied populations confirmed that the tested species of earthworms differ from each other. After 52 weeks of the experiment, the sum of earthworm biomass was higher for D. veneta compared to E. fetida species (18.568 ± 1.867 g and 7.263 ± 1.786 g; p <0.01, respectively). This relationship was confirmed for the average body weight of earthworms (D. veneta: 0.912 ± 0.046 g; E. fetida 0.480 ± 0.006 g; t = 15.95, p <0.01) and cocoons (D. veneta: 0.032 ± 0.003 g, E. fetida 0.014 ± 0.001 g; t = 9.15, p <0.01).

Anesthetic drugs have been tested for years on rats, rabbits, dogs, cats and monkeys, which may raise ethical concerns. Researchers do not always pay attention to the possibility of using techniques of anesthesia, analgesia or euthanasia in relation to invertebrate animals. It has previously
been shown that earthworms meet the requirements of laboratory animals, and being a good alternative to the studies on vertebrates, may also be used as the first stage of testing anesthetics. The lethal concentrations of procaine and lidocaine for E. fetida and D. veneta were established using modified filter paper contact test. Using a modified method developed for testing anesthetics, mature earthworms (clitellate) of both species were used to check the effectiveness of lidocaine and procaine in safe immobilizing of earthworms. The reactions of earthworms in contact with anesthetics were different. The possibility of using a higher concentration range of procaine and lidocaine for E. fetida than for D. veneta, as E. fetida demonstrated a greater resistance to the stress caused by the action of chemical substances. The response to this stress varied and depended on the concentration used; however, higher concentrations of anesthetics caused rapid body movements and discharge of the coelomic fluid as well as morphological changes observed after 48 hours. Procaine was not effective in immobilizing earthworms, but lidocaine proved effective in reversibly immobilizing both species. For E. fetida, lidocaine in the concentrations of 1.4 and 1.6 at 95 and 90 min, respectively, resulted in a full immobilization of animals, which then survived following 24h and 48h of recovery. For D. veneta, lidocaine in the concentrations 1.3 and 1.4 during 40 min proved effective and safe to use, as all individuals survived following 24h and 48h of recovery.
