The manuscript was originally part (though not in the Inventory) of the Rose Collection, Adv.MSS.49.7.1-49.7.20, and was apparently copied for Rose, the work having been completed on the 21st September, 1780 (folio 138); there is an index at the beginning, and some notes by Rose at both the beginning and the end.
