INTRODUCTION.

collect in one point of view the general results deducible from the ensuing detached observations, and enable those who may be unacquainted with Ireland to follow their course with greater facility, it seems desirable to introduce them by a rapid survey of the general features which distinguish the district they refer to.

That district may be described as limited by Dundalk bay on the S.E. and by Lough Foyle on the N.W. including towards the south the counties of Down, Armagh, and the N.E. angle of Lowth lying between Dundalk and Carlingford bay; and on the north, Antrim and Derry: that portion of Tyrone which extends along the S.W. shore of Lough Neagh, between Derry and Armagh, being also comprehended as falling within the same general outline.

This district is marked by three distinct systems or groups of mountains, one of which occupies the more southern counties; while the more northern are divided between the two others.
