waters of Toplitz, a village in Bohemia famous for 

 its baths. These waters were discovered in the 

 year 762 j from which time the principal spring of 

 them had constantly thrown out hot water in the 

 same quantity, and of the same quality. On the 

 morning of the earthquake, between 1 I and 12 in. 

 the forenoon, the principal spring cast forth such 

 * quantity of water, that in the space of half an 

 hour all the baths ran over. About half an hour 

 before this great increase of the water, the spring 

 flowed turbid and muddy j then having stopped 

 entirely for a minute, it broke forth again with 

 prodigious violence, driving before it a consider- 

 able quantity of reddish ochre. After this it be- 

 came clear, and flowed as pure as before. It still 

 continues to do so ; but the water is in greater 

 quantity, and hotter, than before the earthquake. 

 At Angouleine in France, a subterraneous noise 

 like thunder was heard ; andPpresently after the 

 earth opened, and discharged a torrent of water 

 mixed with red sand. Most of the springs in the 

 neighbourhood sunk in such a manner, that for 

 some time they were thought to be quite dry. In 

 Britain, no considerable alteration was observed in 

 the earth, except that, near the lead mine above- 

 mentioned in Derbyshire, a cleft was observed 

 about a foot deep, six inches wide, and 150 yards 

 in length. 



At sea, the shocks of this earthquake were felt 

 most violently. Off St. Lucar, the captain of the 

 Nancy frigate felt his ship so violently shaken, that 

 he thought she had struck the ground : but on
