Russian Church Hirmologium. This was probably purchased by Tillyard at Nizhni Novgorod Fair in 1911. In an account of the visit to Russia, he (or, rather, his mother, with whom he travelled) notes that on 7 August 1911 Julius made a purchase from a shop in which he had earlier spotted 'some old music MSS' 'three books', one of which is likely to be the Hirmologium.
Presented by H. J. W. Tillyard in 1949.
