were portions of a cooking vessel ; they corresponded exactly with 

 some fragments I have found in crannoges ; there were no marks of 

 any kind on these pieces of pottery indicating ornamentation. On the 

 same floor there were hiiman and animal remains found scattered far 

 apart ; and in no instance during the whole exploration of this end 

 of the cave did I find human remains huddled together. 



The fourth layer was composed of yellow clay traversed by veins 

 of brown earth, and yielded traces of charcoal all through, together 

 with human and animal remains. 



The next and lowest stratum rested on the solid rocky floor of the 

 cave, and to my mind is the most important of the series, as it bears 

 evidence showing the extraordinary changes which the surrounding 

 country has undergone since its deposition. In depth it varied from 1|- to 

 2 ft., and consisted of gravel with a covering of sandy clay of a yellow 

 colour about 3 or 4 inches deep. I found no human or animal remains 

 in the gravel, but imbedded in the sandy clay on its surface I picked up 

 two rude flint implements of Palaeolithic type; one of them (fig. 3) was

 about 3 inches each. I submitted the black flint to the Eev. Dr.

 from which the flint flakes were manufactured is found in Fermanagh. 

 I also found in the same bed of yellow clay human remains, including 

 several portions of a skull, the hollow sides of which were filled with 

 the material comprizing the layer. After I brought these portions of 

 skull out of the cave I picked out the clay, which was firmly packed 

 in their hollow sides, and found it identical with the stratum from 

 which they were taken. My object in going so minutely into detail 

 is to show that these portions of skull could not possibly have fallen 

 during the process of exploration from a higher stratum. There were
