'gular ranges of detached rocky hills composed of sand-stone, rising abruptly from extensive plaine of low level land, su- persede the low and woody coast, that occupies almost unia- terruptedly the space between this inlet and Cape Wessell, a distance of more than six hundred miles. Cambridge Gulf, which is nothing more than a swampy arm of the sea, ex- tends to about eighty miles inland, in a southern direction: and all the specimens from its vicinity precisely resemble the older sand-stones of the con6nes of England and Wales *. The View, (vol. i. plate, p. 301,) represents in the distance Mount Cockburn, at the head of Cambridge Gulf; the tint rocky top o? which was supposed to consist of sand-stone, but has also the aspect of the trap-formation. The strata in Lacrosse Island, at the entrance of the Gulf, rise toward the oorth-west,--at an angle of about 30 �h the horizon: their direction consequently being from north-east to south- west. From hence to Cape Londonderry, towards the south, is an uniform coast of moderate elevation; and from that point to Cape IAv?que, although the outline may be in a general view considered as ranging from north-east to south-west% the coast is remarkably indented, and the adjoining sea irregularly studded with very numerous islands. The spe- cimens from this tract consist almost entirely of sand-stone, resembling that of Cambridge Gulf, Goulbum Island, and �I use the term ' OM Red Sand Stone,' in the acceptatiou of Messrs. Buckland and Conybe3re, "Observations on the South Western Coal District of England." OeoL Trans, Second Serle?, Vol. L--Captain King's specimens from Lacrosse Island are not to be distinguished from the slaty strata of that formation, in the banks of the Avon, about tyro miles belov? Cli?on. t The large chart (Sheet V.) best shews the general range of the shore, from the islands filling up the inlets..
