chimneys, which, instead of being an eye-sore, as is generally 

 the case, are by no means the least elegant feature in the 

 building. The Stafford knot, with the date 1514, attests 

 their antiquity, though the sharp moulding of the bricks by 

 no means indicate such a lapse of years. 



The remaining part of the day was devoted to an exami- 

 nation of the weU-known Aust Cliff, with its " bone bed" so 

 full of traces of ancient life, to which the age of the Castle, 

 or even of those Romans who used the Augusti trajectus, is 

 but as yesterday compared with the ceons which have elapsed 

 since those deposits were laid down. Diligent use was made 

 of the waning day, and after a general view of the section had 

 been obtained from the end of the causeway, where the 

 three faults, and the succession of the different beds, from the 

 red marls to the lowest beds of the has which cap the top, 

 are best seen, some preliminary remarks were made as to the 

 conflicting views held by Dr. Wright and Mr. Charles Moore 

 respecting the true position of the Avicula contorta beds ; 

 the former being of opinion that these beds, which are here 

 represented by intervening bands of black shales, argillaceous 

 limestone, and calcareo -arenaceous beds, with the celebrated 

 bone-bed at the base, belong to the Keuper marls below ; 

 whilst the latter states that these shales, &c., are the only 

 representatives in this country of the Ehcetic formation, which 

 assumes so vast a thickness on the continent, thus placing 

 them on a higher horizon. Mr. ]\Ioore also states that these 

 Avicula contorta beds are almost invariably overlaid by the 

 White Lias, which latter bed he also includes in the Rlioetic 

 formation. The Members, however, in their walk along the 

 beach failed to trace a single specimen of the true White 

 Lias rock, although specimens of eveiy other bed which 

 exists in the section were found. Many specimens of fish 

 teeth, scales, and saurian bones, Ostrea liassica and other 

 shells were found in abundance.
