WE have recently referred in several articles to the efforts which are being made to introduce a more satisfactory organisation among the various scientific institutions in Dublin, which have hitherto been independent of each other. It appears now to be proposed not merely to unite museums, but to unite into one body the Royal Irish Academy and the Royal Dublin Society. This project would seem to have originated at a meeting which a deputation from the latter body had with Major Donnelly. It is evident that many difficulties would be removed and many advantages result from the amalgamation of these two societies. Of course the arrangements for such an amalgamation must be carried out entirely by the societies, though it would no doubt tend to forward such a scheme if the societies were assured of the approval of Government, and of such aid towards taking the necessary steps as the Government has in its power to give.
