Comprises manuscript copies of correspondence and other texts written by the physician William Butler. Evidently the vast majority are not the documents which were sent or received, but rather contemporary drafts or file copies. None of William Butler's letters are dated, neither are any of the recipients clearly identified. Most of the texts are in William Butler's own distinctive hand, some by another, possibly two, scribes.
There are also a handful of letters received by Butler - some original, some copied - from significant contemporaries (CCPP/BTLR/31-35). The correspondents include Samuel Harsnett, Bishop of Chichester (1561-1631), Robert Cecil (1563-1612), Susan de Vere, Countess Montgomery (1587-1628/9) and Samuel Collins (1576-1651). There is also a manuscript of what appears to be a latin eulogy by William Gager (1555-1622), as well as another anonymous latin verse text (CCPP/BTLR/25B).
