Note 1 — Chapter I
Reading edition
: The barrier known as Adam's Bridge, which obstructs the navigation of the channel between Ceylon and Ramnad, consists of several parallel ledges of conglomerate and sandstone, hard at the surface, and growing coarse and soft as it descends till it rests on a bank of sand, apparently accumulated by the influence of the currents at the change of the monsoons. See an Essay by Captain STEWART on the Paumbem Passage. Colombo, 1837. See Vol. II. p. 554.
