1 68 The Irish Naturalist. 



With the exceptions of that for Co. Dublin, this is, as yet, 

 the only important list of Poh^zoa we possess for Ireland. 

 The study of these minute, but interesting forms, has been 

 much neglected in our country compared with England and 

 Scotland. Especially have the north and west coasts suffered. 

 Owing to the efforts of recent surveys, however, much is now 

 being done in this group, and already some new and many 

 rare forms have been obtained. Mr. Duerden, who is now 

 working at the Irish Polyzoa and Hydrozoa, will be ver}^ glad 

 to receive specimens from an}' part of the coast, but CvSpecially 

 from the north and west, addressed to the Ro3^al College of 

 Science, Dublin. 



THE BEAUTY AND USE OF IRISH BUILDING 



STONES. 



BY PROF. GRKNVILI.B A. J. COLE, M.R.I. A., P.G.S.

\y:h February, 1 893.) 



From a decorative point of view the beauty of a vStone depends 

 on its effect upon the eye. In suitable surroundings, there is 

 a rich beauty in the renowned black marbles of Galway and 

 Kilkenny, or in the streaky grey limestones, passing into 

 marble, common throughout the Carboniferous series. There 

 is an inherent beauty in the variegated ** Cork Red," which is 

 now being largely used in I^ondon, and which has something- 

 firmer and more jaspery in its tone than the veined red marbles 

 of South Devon. And, above all in this quality of obvious 

 beauty, beyond all the ornamental stones yet quarried or 

 detected in the British Isles, we have the serpentinous lime- 

 stones of Co. Galway, the famous " Connemara Green." 



But to the stonecutter and the builder, as well as to the 

 geologist, there is a beauty in a good stone beyond that which 

 appeals openly to the eye, a beauty more subtle, requiring a 

 scientific as well as an artistic appreciation — the beauty of 

 la'stingness, of durability. An architect's work is not to be 

 padded up with wool and protected for posterity in the glass-
