borhood, produces according to an examination by Mr. Faraday, a 

 deposit almost precisely similar ; that no remains of Serpulje, or 

 other marine animals, are found adhering to it. 



4. The temple continuing to subside, its area was again partially 

 filled with solid materials; at this period it appears to have been 

 subjected to a violent incursion of the sea. The hot water lake 

 was filled up, and a new bottom produced, entirely covering the for- 

 mer bottom, and concealing also the incrustation of carbonate of 

 lime. TJie proofs are, that the remaining walls of the temple are 

 highest on the inland side, and decrease in height towards the sea 

 side, where they are lowest, that the lower boundary of the space 

 perforated by the Lithophagi is, on different columns at different 

 distances beneath the uppermost or water level line, &;c. that sev- 

 eral fragments of columns are perforated at the ends. 



5. The land continuing to subside, the accumulations at the bot- 

 tom of the temple were submerged, and Modiolae attaching them- 

 selves to the columns and fragments of marble, pierced them in all 

 directions. The subsidence continued until the pavement of the 

 temple was at least nineteen feet below the level of the sea. 



The proofs are derived from the condition of the columns and 

 fragments. 



6. The ground on which the temple stood, appears nowto have been 

 stationary for some time, but it then began to rise. A fresh deposi- 

 tion of tufa or sand, was lodged for the third time, within its area, 

 leaving the upper part of three large columns visible above it. 

 Whether this took place, before or subsequently to the rise of the 

 temple to its present level, does not appear, but the pavement of the 

 area is at present level with the waters of the Mediterranean. 



The author then states several facts, which prove that considera- 

 ble alterations in the relative level of the land and sea have taken 

 place in the immediate vicinity. An ancient sea beach extends 

 near Monte Nuovo, tv»o feet above the present beach of the INIedi- 

 terranean ; the broken colunms of the Temples of the Nymphs and 

 of Neptune, remain at present standing in the sea — a line of per- 

 forations of Modioli and other indications of a water-level four feet 

 above the present sea, is observable on tl>e sixth pier of the bridge 

 of Caligula ; and again on the twelfth pier, at the height of ten feet, 

 and a line of perforations by Modiolae, is visible in a cliff opposite 

 the island of Nisida, thirty two feet aboye the present level of the 

 Mediterranean.
