The paper offers a comprehensive analysis of a bundle containing one Tibetan and six Mongolian folios, preserved at the Hunterian Library of the University of Glasgow. These folios were originally part of the private library of Th. S. Bayer, the first Orientalist at the Saint Petersburg Academy of Sciences. Additionally, one of the appendices to the article includes the second part of the catalogue of Tibetan folios on blue paper, believed to have originated from the Sem Palat library.
