The President made a communication on the arrangement of earthen 

 raths, — commonly, though erroneously, known as Danish forts, — over 

 the surface of Ireland ; his observations having a special reference to the 

 county of Kerry, and being illustrated by a map constructed on the one- 

 inch Ordnance Survey, with the lines of collineation laid down accord- 

 ing to the disposition of the forts. 



The President signij&ed his intention of making a further commu- 

 nication on the subject, illustrated by a map of the entire county of 

 Kerry ; and expressed a hope, that, as he would be unable to deal in 

 like manner with the whole of Ireland, other members of the Academy 

 would pursue the inquiry, and construct similar maps of other counties. 



The Academy then adjourned.
