Exhibit of the Month is a series initiated by the Jagiellonian University Museum with the beginning of the new academic year. Each month we will explain the Museum collection to you, choosing a single exhibit or a group of exhibits which usually are not shown to the open public. This month's feature is a collection of objects related to the history of the Medical Faculty, including preparation instruments formerly owned by Professor Henryk Hoyer (physician, anatomist, histologist, JU professor, the founder of the Cracow school of zoology), microscopes and historical photographs.
