with a chain, which, being made of silver, was worth 300 cows, 

 with other valuable rarities." — Ogygia, II. pp. 182-183. 



The same author informs us that about the middle of the 

 third century, Cormac, the 126th Monarch of Ireland,

 of the Picts, Saxons, Scots, and Attacots, reduced the Britains 

 to the utmost distress." Hence, he concludes, there was a 

 common league between them, with intermarriages and com- 

 mercial intercourse.

 into Ireland, the wonder perhaps should be, not that so many, 

 but that so few, have been discovered.

 Account of some Characters found on Stones on the top of 

 Knockmany Hill, county Tyrone."

 vaen, consisting of upright flag-stones, about six feet high. 

 It includes a space fourteen feet long by seven wide. Its po- 

 sition with respect to the moats is represented in the ground 

 plan, fig. 1. The stones marked by a darker shade are
