Description:
During my visit to Dublin, last autumn, I was greatly grieved to learn that many of the curious inscribed and carved stones of Clonmacnoise, Glendalough, and other localities, of which descriptions and figures (more or less perfect) had been published, have, within the last few years, been entirely destroyed, without any further record being preserved of them whereby doubts which might arise respecting the correctness of the descriptions or figures might be solved.
