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-Earne, 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 sliminess, that bleaches linen much sooner than could be done by other water. In one part of the country are marble rocks 50 or 60 feet high. This county sends three members to parliament, viz. two for the shire, and one for Inniskillen the capital. See FERMANAGH, Supplement.
