^{page 164 note 1} Since this paper was sent to press, Mr. P. O. Hutchinson, of Sidmouth, informed me that the occurrence of pseudoraorphous crystals of rock-salt had been noticed by Mr. Ormerod and himself in the Upper Marls, near Salcombe Mouth; I have since obtained a few specimens from that locality, and also, in descending the cliffs at Wind Gap, between High Peak and Peak Hills, west of Sidmouth, was very fortunate in obtaining numerous slabs exhibiting well-marked pseudomorphs and ripple-markings.

^{page 168 note 1} Since the above was written, Mr. P. O. Hutchinson, of Sidmouth, kindly furnished me with a sketch section of the railway cutting between Langsant Point and Dawlish, made during a visit to the latter place, and showing, besides numerous small faults, one of considerable importance, on the west side of Langsant Point; as the Breccia occurring at that Point and in the plantation at Exmouth is almost exactly similar to that exposed in the cliffs, by the beach, on the west of Dawlish, and the beds in the railway cutting chiefly consist of sands, the probability of these latter being representatives of a part of the sandstones of the division No. 5, cut out by the fault at Exmouth, immediately struck me. Future investigation will probably supply the solution, which, if my inference be correct, would lead to a further reduction in the estimation of the thickness of division No. 5.
