The „galenical“ dissertation which was presented for disputation by Georgius Horčička at Charles University in 1841 is discussed as far as its content is concerned. The dissertation studies a great number of pharmaceutical dosage forms, many of which are already obsolete, but a certain number of which are still in use in the present time. It is probably one of the first dissertations treating of the given subject.

        Key words: Charles University – pharmaceutical dosage forms – history of pharmacy – nomenclature of ancient pharmaceutical dosage forms
