feet. The latter bed contaiued few fossils except Belemnites. The rock-beds 

 consisted of brown or grey sandstone, shewing frequent dark-red feruginous 

 stains on the surface. The rock appeared to have been originally of a 

 grey colour, but the feruginous stains had changed the softer portions to a 

 brown, whUe the harder parts were only stained to the depth of two 

 or three inches. 



Belemnites paxillosus, Schloth, and Rhynchonella variabilis, Schloth, 

 the latter occasionally in clusters, were the prevailing fossUs, a few 

 specimens of Avicula inoequivalvis, Cardinia Listen, and TTnicardium 

 cardioides, Phil., were observed. 



A section of the upper beds may be seen on the north-east side of the 

 canal, near the railway station. 



On passing through the uppermost bed the marls and clays of the Upper 

 Lias were entered, the lower parts of which shewed feruginous stains in 

 the lamination similar to those in the Marlstone beneath. It contained 

 numerous water- worn sandstones generally flat and varying from one to 

 three inches in thickness, frequently containing fragments of Ammonites 

 serpentinus, Rein. This species, as well as A. communis. Sow., were 

 abundant, and one specimen of a Nautilus was obtained. 



There was a gravel deposit also exposed a few feet above the Marlstone. 

 It was not extensive. It contained numerous small specimens of A. lifrons, 

 Brug., badly preserved. 



Passing a short distance farther up the slope on which the town stands 

 the water- worn stones and Ammonites disappeared and the deposit assumed 

 a darker colour, and towards its upper portion there were frequent blue 

 stains which gave it a mottled appearance. There was a total absence 

 of rock as well as fossil remains. The junction of the Lias clay and 

 marls with the Sands was found to be gradual. At first there were 

 merely traces of sand mixed with the marl, then a few feet higher up 

 the slope the deposit partook of a sandy character, and then the marl 

 disappeared leaving a pure fine sand varying in colour from pale to deep 

 buff. In one instance in the transition deposits the Sands assumed a 

 concretionary character, a few sandstones were thrown out of the trenches, 

 but it was not ascertained if they formed part of a distinct bed. 



The altitude of the upper surface of the Sands could not be ascertained 

 in consequence of the great depth of rubbly stone overlying the deposit, 

 they were found at an elevation of 380 feet, and in the bottom of a trench 

 at 450 feet a small quantity of sand was exposed identical with that in the 

 excavations lower down the hill. 



A (so-called) sea beach was exposed on the slope of Sti'OudhUl at an 

 elevation of 378 feet. It was about 200 yards in length, and composed of 

 angular oolitic gravel very clean and fine ; a similar deposit occurs at
