Ruskin's first catalogue of 300 works for the instruction of undergraduates and his notes on the use of particular examples.
According to Cook and Wedderburn (XXI.305), the Supplementary Cabinet was 'a cabinet which Ruskin placed in the School but did not fill'; the examples which they listed were placed there shortly before their catalogue was published in 1906.
Presented by John Ruskin to the Ruskin Drawing School (University of Oxford), 1875; transferred from the Ruskin Drawing School to the Ashmolean Museum, c.1949.
