XORULLO, or Jorullo, Volcano of, in Geography, a 

 bafaltic cone of New Spain, which appeared above ground 

 on the 15th of September 1759, and which is at this day 

 249 fathoms or 1494 feet above the furrounding plain. 

 It is fituated in the province of Mechoacan, at the diftance 

 of eight leagues from Pafquaro the capital, towards the 

 S.W. ; the volcano of Colima being in the fame direftion, 

 but at a greater diftance. A delicious and fertile vale, 

 eight leagues in length from N. to S., and three in breadth, 

 was called Xorullo by the Indians, a word in their language 

 fignifying /)arj(///i'; but upon the eruption of the volcano, 

 this valley affumed an infernal afpeft, blackened with per- 

 petual fmoke, covered with deformed rocks and afhes, the 

 trees confumed, the earth full of deep breaks and openings, 

 and now forming a hill of confiderable height, crowned with 

 a volcano. A rivulet which fertilized the valley is now fo 

 hot as to burn men and animals who attempt to pafs it, which 

 is peculiarly inconvenient, as it is in the direft road to the 

 copper-mines in this quarter. Before this cataftrophe, 

 there were conftantly heard horrible fubterraneous noifes, 

 and earthquakes were felt, which excited confternation in 

 the inhabitants.
