Paper manuscript compiled for Robert Shipboy MacAdam in the middle of the 19th century, containing a substantial, alphabetically arranged collection of materials made in preparation for an English–(Ulster) Irish dictionary. The project was undertaken by MacAdam, who worked together with Aodh Mac Domhnaill, a native speaker from County Meath. The manuscript consists of 23 (port)folios, lacking letter F and the beginning of G, and numbers around 1145 pages. The dictionary remained unpublished.
