xviii PREFACE. 



was especially obliging in affording information ; as well 

 as John Cuxson, Esq., of Eaglaii ; and at Badminton, 

 John Thompson, Esq., materially assisted in procuring 

 the required manuscripts, and affording facilities for 

 copying them, for which kindly aid the author can but 

 insufficiently here express his obligations. The author 

 is likewise greatly indebted generally to the rich stores 

 of the British Museum, and the obliging attentions of 

 its principal officers ; to the State Paper Office, where 

 he was especially assisted through the kindness of Mrs. 

 M. A. E. Green, with the uncalendered papers given at 

 pages 249, 270, 286, and 287, and to John Bruce, Esq. 

 Also to the excellent Libraries of the Royal Society ; 

 the London Institution ; and the particularly valuable 

 scientific collection of the Patent Office. At Oxford, 

 the privilege of consulting works and manuscripts at 

 the Bodleian Library, was freely granted, and every 

 facility afforded. The author would especially notice 

 among other contributions of information, the able 

 assistance of Bennet Woodcroft, Esq., F.R.S., &c. To 

 the Eev. John Webb, of Hay, he is particularly in 

 debted for the papers at pages 64, 88, and 142, to which 

 that gentleman directed his attention, and which he 

 might otherwise have overlooked. He has also received 

 assistance from the collections of Robert Cole, Esq., and 

 of the late Dawson Turner, Esq., which are noted where 

 they occur. When inquiring for the autograph of 

 &quot; Glamorgan,&quot; every possible effort to trace it, although 

 unavailing, was kindly employed by the Librarian of 

 St. Cuthbert s College, Durham, and by the Rev. Dr. 

 Grant, the Roman Catholic Bishop of Southwark. 



During the author s visit to Dublin, Sir Bernard 

 Burke, Ulster King at Arms, very obligingly searched 

 for any documents referring to the Earl of Glamorgan, 

 that might be in Dublin Castle, but without success ;
