In the Paper submitted to the Royal Irish Academy, the 22nd Feb- 

 ruary, 1903, " On the Orientation, &c., of the Old Churches of Dalkey 

 Island and of Dalkey Towd," the description thereof by Wakeman, 

 in the Paper by him therein cited, was taken as a text. In it he also 

 makes mention of the old chui'ches of Kill-of-the-Grange and of 

 Killiney; and points them out as remarkable by their evident 

 antiquity, and the interest attaching to the details of their architec- 

 ture. Having, in my Paper on the Dalkey chui'ches, arrived at certain 

 conclusions as to the significance of their orientations, and as to the 

 unit of measurement which had been employed in the construction of 

 the old church of Dalkey Island, and showed it to have been the 

 Spanish vara of 835 mm. (2' 8-88"), I was led to examine in a 

 similar way such other ancient churches as are existing in the 

 neighbourhood of Dublin, and which would be likely to illustrate and 

 lend support to the conclusions arrived at in the Paper before 

 mentioned. 



I commenced with the Kill-of-the-Grange, and made a plan of the 

 old nave as it now stands. Of the chancel so little remains that 

 nothing well-defined or satisfactory for purposes of comparison could 

 be made out. This old structure fully bears out the statements made 

 concerning it by Wakeman, and would fully justify the making of a 

 completely detailed plan, with sections and elevations, as a matter of 

 historical record. Being, however, concerned only with certain of its 

 details, my attention was more particularly confined to these, to the 

 exclusion of others, interesting in themselves, but which did not bear 

 on the object of the present Paper.
