Abstract
O n referring to a map of Bahia, it will be seen that a line of hills runs from the Point of St. Antonio in a north-easterly direction. They form for some distance steep rocky cliffs, skirting the Bay, and continue in the same direction for several miles. They also form the seaward exposed edge of an elevated range of country, and present a steep slope to the N.W.; and are everywhere covered by red loam or sand, except where exposed to the action of the sea. These are gneissose rocks, usually exhibiting distinct lines of stratification or foliation, but not unfrequently passing into amorphous masses (see Map, fig. 1). The direction of the general line of upheaval clearly coincides with that of the above range of hills, being N.E. and S.W.; the dip of the gneiss, where it can be well made out, being always to the N.W. In Itapagipe Bay, near Cabrito, there is a white sandstone, interstratified with shale, the dip of which is also to the N.W. It forms a low hill, running nearly parallel with the gneiss hills, at a distance from the latter of three or four hundred yards in the direction of the dip (fig. 2). No organic remains have yet been discovered here; but this deposit has not been carefully examined. At a distance of about two miles from the gneissose range, and running parallel with it, is the isolated hill of Montserrate (see Map, fig. 1), which extends for nearly a mile
