A letter from Daniel Mylrea (likely a revenue official or administrator in the Isle of Man) to the Duke of Atholl dated 1 August 1764, discussing the positive reception of the Duke's recent communication among Manx merchants. Mylrea reports that merchants are relieved of fears about a 'revolution' (likely political change) and indicates plans for a revenue collection at Douglas. This document is directly relevant to the period immediately preceding the 1765 Revestment negotiations.
