When you can come at Llyfr Coch o Hergest, or any other ancient MSS., I will send you directions to read it, and understand it: the chief difficulty being in the orthography: the language of all Britain (even Scotland) was the same as it is now in Wales, 1200 years ago. I wrote to you lately, which I suppose you had not received when you sent your dateless letter. I desire your answer when convenient. Yours sincerely, LEWIS MORRIS. _Galltvadog_, _July_ 14, 1751. * * * * * The same to the same. DEAR EVAN, Your letter of the second instant, I received this day; and I was very glad to hear that you had procured leave to go to the private library in Jesus College. It is charming to get into conversation with _Llywarch Hen_, _Aneurin_, _Merddin_, &c. They are most pleasing old companions. I understand that my copy of _Brut y Brenhinoedd_ is not the same with that in _Llyfr Coch o Hergest_. Mine was copied out of five MSS. three of them upon vellum, very ancient; but the transcriber, not understanding the occasion of the difference between the copies, stuffed all into this, that he could find in all the MSS. Had he known that some of those MSS. were from Walter the Archdeacon’s original translation of the history, out of the Armoric; and some again from his second translation from Galfrid’s Latin, he would have kept the copies separate. The transcriber of my copy mentions sometimes—“thus in such a MS. and thus in such a MS.,” but it is impossible to find which is which.
