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.”
