Daniel bought copies of the first four folio editions of Shakespeare's works, and of many of the quarto editions of separate plays.
On 22 August 1835 he bought at Charles Mathews's sale, for forty-seven guineas, the cassolette, or carved casket made out of the mulberry-tree of Shakespeare's garden, and presented to David Garrick with the freedom of the borough of Stratford-on-Avon in 1769.
