This loss of the work is most painful to the student of the early history of Erinn.

It is believed that the ancient compilation known as Cormac's Glossary, was compiled from the interlined gloss to the Saltair; and the references therein to our ancient history, laws, mythology, and social customs, are such as to indicate the richness of the mine of ancient lore.

A copy was in existence in 1454, as there is in the Bodleian Library in Oxford (Laud, 610) a copy of such portions as could be deciphered at the time.

This copy was made by Shane O'Clery for Mac Richard Butler.
The subjoined list of the lost books is taken from O'Curry's _MS.
Materials_, page 20.

It may be useful to the philologist and interesting to our own people, as a proof of the devotion to learning so early manifested in Erinn:-- "In the first place must be enumerated again the _Cuilmenn_; the Saltair of Tara; the _Cin Droma Snechta;_ the Book of St.Mochta; the Book of _Cuana_; the Book of _Dubhdaleithe_; and the Saltair of Cashel.
