William Pike, Esq. presented to the Academy an Irish 

 Quern, and some other ancient remains, found at Roughan 

 Island. 



On removing the dam from the millrace, leading from 

 Roughan lake, near Dungannon, when the water subsided, 

 an island appeared nearly in the middle of the lake, which, 

 on examination, appeared to have been artificially formed 

 of timber and peat. The quern presented was found on 

 the surface ; and numerous fragments of ancient pottery, 

 and bones, and a few bronze spear heads, were discovered at 

 the depth of a few inches. 



Mr. Patterson exhibited to the Meeting a massive Gold 

 Ring, (of the form supposed to be the ancient ring-money,) 

 recently found near Belfast. 



The President continued his account of his "Second Se- 

 ries of Researches respecting Vibration."
