a county of Ireland, in the province of Ulster; bounded by Cavan on the south, Tir-Oen on the north and north-east, by Tyrconnel on the north-west, Leitrim on the south-west, and Monaghan on the west. It is 38 miles long, and 24 broad. A great part of it is taken up with bogs; and the great lake called Lough-Erne, which is near 20 miles in length and in some places 14 in breadth, diversified with upwards of 300 islands, most of them well wooded, inhabited, and covered with cattle. It abounds also with great variety of fish, such as huge pike, large bream, roach, eels, trout, and salmon. The water of the lake in some places is said to have a particular softness and limpidity, that bleaches linen much sooner than could be done by other water. The lake is divided into the upper and lower, between which it contracts itself for five or six miles to the breadth of an ordinary river. In one part of the country are marble rocks 50 or 60 feet high. This county formerly sent four members to the Irish parliament, viz. two for the shire, and two for Inniskillen the capital. Fermanagh gives the title of vicount to Earl Verney.
