[Jan Evangelista Purkynĕ and his instruments for microscopic research.].

The results obtained during the studies of the microscopic structure of animal and human tissues by the famous 19th century Czech scientist Jan Evangelista Purkynĕ are already sufficiently described in a variety of older and newer publications. The contents of the present paper are an overview of the microscopes and other tools and instruments that Purkynĕ and his assistants and pupils used for research of tissue histology and during teaching, and in whose development there were directly involved. A brief overview of the development of the cutting engines suggests that the first microtome, from which all modern sliding microtomes are derived, originated under the supervision of Purkynĕ at the Institute of Physiology in Wroclaw. Purkynĕ and his assistants thus not only obtained priority results in the field of the structure of animal and human tissues, but also substantially contributed to the development of instruments and equipment for their study, which is often forgotten today.
