may be zero from the numbers resulting from the corresponding 

 transformation in the other operation, there might be uncertainty, in 

 the absence of proof, as to whether the indications of imaginarity, when 

 we operate upon JSl 0 = 0, might not be delayed beyond the step at which 

 they would offer themselves if we were to operate upon X p = 0 itself ; 

 we now see that such delay can never occur; but that the fulfilment or 

 the failure of the prescribed condition, for any triad of coefficients in one 

 of the transformations of X 0 = 0, implies the like fulfilment or failure for 

 the corresponding triad of coefficients, in the corresponding transforma- 

 tion (by the same number) of X p = 0. 



And hence the remarks, at p. 378, respecting equal and nearly equal 

 imaginary pairs entering X 0 = 0, equally apply whenever such pairs 

 enter a derived equation. 



XXXIX. — On an Ogham-insceibed Monument in Glen Fais, County 

 Keeet. By Richaed Rolt Bbash, M. R. I. A. 



[Read November 9, 1868.] 



On November 8th, 1858, a paper of considerable interest was read 

 before the Royal Irish Academy by the late Venerable the Archdea- 

 con of Ardfert, Dr. Rowan, giving an account of the discovery by that 

 gentleman of a remarkable inscribed monument in Glen Pais, and of 

 the historic locality in which it was found. As the readings given in 

 the Archdeacon's paper appeared to me unsatisfactory, as also those 

 given in other publications, I was anxious to obtain a personal inspec- 

 tion of the stone in question, to ascertain if the published copies, 

 as well as others in my possession, were correct, as I have had abundant 

 reason to distrust copies of Ogham inscriptions, unless made by very 

 experienced and trustworthy Oghamists. Being on an antiquarian tour 

 in the barony of Corcaguiney, in July of the present year, I had an oppor- 

 tunity of gratifying my desire, by visiting the locality of the monu- 

 ment, which I found lying prostrate in a grass field in the townland of 

 Camp, a portion of Glen Fais, or, as it is locally pronounced, Glenaish, 

 under the west face of Caher Conrigh mountain. It lies about twenty 

 yards inside the fence, to the left of the public road winding up the 

 glen, and about ten minutes' walk from Camp Post-office ; distant from 

 Tralee nine miles. The locality will be found on sheet ISTo. 37 of the 

 Ordnance Survey of Kerry, on which, however, the monument is not 

 marked. It is an irregular flag-shaped monolith, measuring in length 

 eleven feet five inches, and in extreme breadth five feet nine inches, 

 and varying in thickness from ten to eighteen inches; it is a hard, 

 compact, close-grained red sandstone, the inscription being on an 

 obtuse angle on the face of the stone towards the left, and about 

 midway in the length of the monolith. The engraving which 

 accompanied Dr. Rowan's paper ("Proc. R.I. A.," vol. vii. p. 104), 

 is a fair representation of the stone, while the inscription is, I am happy 

 to say, accurately copied. The line on which the characters run is
