jacent, were almost totally destroyed by them twice, within the 
compass of about sixty years, scarce. any building being. left 
standing, and the latter being both times overflowed by the sea: 
ner were these the only instances of the like kind which have 
happened there: for, from the year 1582 to 1746, they have had 
no less than sixteen very violent earthquakes, besides an infinity 
of less considerable ones; und the Spaniards, at their first settling 
there, were told by the old inhabitants, when they saw them 
building high houses, that they were building their own sepul- 
chres*, 
9. Secondly, Those places that are in the neighbourhood of 
burning mountains, are always subject to frequent earth- 
quakes ; and the eruptions of those mountains, when vio- 
lent, are generally attended with them. vei 
10. Asia Minor and Constantinople may be looked upon as its 
the neighbourhood of Santerini. The countries also about Etnat, 
Vesuvius, Mount Hecla, &e. afford us sufficient proofs to the 
same purpose. But, of all the places in the known world, I 
suppose, no countries are so subject to earthquakes, as Peru f, 
Chili, and all the western parts of South America; nor is there 
any country in the known world so full of voleanos: for, through- 
out all that long range of mountains, known by the name of the 
Andes, from 45 degrees south latitude to several degrees north 
of the line, as also throughout all Mexico, being about 5000 
miles in extent, there is a continued chain of them §. 
_ 11. Thirdly, The motion of the earth in earthquakesis partly 
tremulous, and partly propagated by waves, which succeed 
one another sometimes at larger and sometimes at smaller 
distances ; and this latter motion is generally propagated 
wouch further than the former. Na 
12. The former part of this proposition wants no confirmation : 
for the proof of the latter, viz. the wave-like motion of the earth, 
we may appeal to many accounts of earthquakes: it was very 
remarkable in the -two which happened at Jamaica.in 1687-8 4 
and 1692. In an account of the former, it is said, that a gen- 
* * What is here said, is taken from d’Ulloa’s Voyage to Peru, the History 
and Philosophy of Earthquakes, the Philos. Frans. &c., where many more 
examples, to the same purpose, are to be met with. See also Memoires sur 
les Tremblemens de Terre; in which are mentioned above 130 repetitions 
ofearthquakes that have happened within the compass of 960 years in 
Switzerland.
