Resumo

Lough Corrib is a long irregular lake of various widths, but having a general bearing of about N.W. and S.E. Its N.W. portion is in a granite and metamorphic rock country, while the rest of it overlies Carboniferous rocks, principally limestone. The northern portion is deep, the southern shallow, and through the whole of it are scattered numerous islands which, in the former part, are generally composed of Boulder-clay, while those in the latter portion are nearly always rock. Its known natural outlets are two, one being over the barrier of metamorphic rocks at Galway (U on Map, Pl. XIX), and the other subterranean passage south of Castlegar (T on Map, Pl. XIX). On all sides of the lake are rocks extending under it, or, to use Professor Ramsay's term, it lies in a “Rock-basin.” What excavated this Rock-basin? I propose in this paper to consider.
