information as to its fortunes during the fourteenth and fifteenth centuries. 

 I have endeavoured to place the documents in chronological order ; but as in 

 many eases the date has to be deduced from the names of the witnesses, it is 

 not always possible to be precise. It has seemed worth while to add some 

 notes as to the Anglo-Norman barons and their retainers who appear in the 

 Charters, as many of their descendants are still to be found in the South of 

 Ireland. Not much is known about the monastery of Duiske, except what 

 these Charters reveal ; but I have supplied in my commentary any details 

 that can be learnt from Clyn's Annals, or (for the later period) from the State 

 Papers. It is the hope of Lady Constance Butler and myself that the 

 material here collected may be serviceable to students of Irish history. 



We desire to thauk Mr. Goddard Orpen for some valuable notes, and Mr. 

 Manning Robertson, A.R.I. B. A., for the map which he kindly drew for the pur- 

 poses of this memoir. Dr. Carrigan has been good enougli to annotate the 

 Terrier of the lands of Tulachany (no. 107) ; and Mr. E. C. K. Armstrong has 

 given ki))d help in connexion with the seals attached to the Charters. We are 

 also under obligation to the President and Council of the Royal Society of 

 Antiquaries of Ireland for permission to reprint tlie plan of the abbey ruins, 

 and the careful nolo upon them, published in their Journal by the late 

 Dr. Robert Cochrane.
