The cicerone, too, who had exercised his profession for thirty years, 
said, he knew a difference of at least 3 feet 6 inches in the height of 
the sea upon the piers of the Bridge of Caligula, giving the same 
amount of subsidence yearly. There were, besides, many similar 
proofs in the partly submerged houses and causeways of Puzzuoli. 
The perforations of the Pholades in the columns indicate a former 
period, during which the temple remained submerged at a stationary 
level ; and contemporary accounts state, that, by an instantaneous 
movement, it was lifted to some height above the sea, which receded 
nearly 200 paces, leaving an immense quantity of fish, which were 
collected by the inhabitants. This took place in October, 1538, im- 
mediately before the elevation of Monte Nuovo. 
7. Notice of an Earthquake and a probable Subsidence of the Lad 
in the district of Cutch, near the mouth of the Koree, or Eastern 
branch of the Indus, in June, 1845. (Extracted from a letter to Capt. ig 
Nelson, R. E.—Journ. Geol. Soc. 1845, p. 103.) —** One of Capt. Me- .'¢ 
Mardo’s guides was traveling on foot to him from Bhooj. The day he he 
reached Luckput there were shocks ‘of an earthquake, which shook 
down part of the walls of the fort, and some lives were lost. . At the 
same time as the shock, the sea rolled up the Koree (the eastern) mouth | 
of the Indus, overflowing the country as far westward as the Goongra : 
river (a distance of twenty English miles), northward as far as a little : 
north of Veyre (forty miles from the mouth of the Koree), and east- A 
ward to the Sindree Lake. The guide was detained six days (from t 
June 19th to 25th), during which time sixty-six shocks were counted. ‘i 
He then got across to Kotree, of which only a few small buildings on 
a bit of rising ground remain. Most of the habitations throughout the 
district must have been swept away, the best houses in Scinde being 
built of sun-dried bricks, and whole villages consisting only of huts 
made of a few crooked poles and reed mats. The guide travelled 
twenty miles through water on a camel, the water up to the beast’s 
Of Lak nothing was above water but a Fakeer’s pole (the flag- 
staff always erected by the tomb of some holy man); and of Veyre 
and other villages only the remains of a few houses were to be seen. 
“ There are said to be generally two earthquakes every year at Luck- 
put. The Sindree Lake has of late years become a salt-marsh.” © 
8. On the Vorticose Movement assumed to accompany Earthquakes ; 
by R. Mauer, (Phil. Mag. xxviii, 587, June, 1846.) —The phenomenon 
to which Mr. Mallet refers, is the apparent displacement and twisting 
of the stones of a column of masonry, as if produced by a partial revo- 
- lution around a vertical axis. He shows that the supposition of an ac> 
tual vorticose movement in the earth is not only improbable, but unne- 
‘ere to.account: for the facts: > inane ——
