 Knockninny hill rises about 700 feet on the S. shore of Lough Erne, 

 about 10 miles from Enniskillen ; and the cave occurs on an escarpment 

 at about 380 feet above the valley, and is a fissure 2 to 6 feet wide, 4 

 to 10 high, and extending 51 feet to a second entrance. It was filled 

 with fine layers of debris and cave-earth, in which occurred flint im- 

 plements, cinerary urns (containing burnt human bones, evidently in 

 a place of sepulture), and also scattered fragments of human bones, 

 as well as those of various animals, a list of which is given in an 

 appendix by Profs. Haughton and Macalister. E. T. H.
