NAIRN, the county town, and a royal burgh, is a place of considerable antiquity, pleasantly situated on the northern bank of the Nairn, near its mouth. It has no manufactures, and but little trade, and contains about 2000 inhabitants. The National Bank and the British Linen Company have opened branches here, and an academy has lately been erected by subscription. Nairn has an excellent inn, with hot and cold salt-water baths; and from the dryness and salubrity of the climate, it is much resorted to in summer for sea-bathing.
