say an Ave Maria ; the motion was sudden, and the shaking of the house was 

 from east to west. At 10 hours and a half, were perceived 2 other shocks, 

 with a small intermission of time, much like the 2 former. Another shock 

 waked him at 1 H, and another about an hour after. 



In the morning of Jan. 17, after the last shock, there fell a little small rain, 

 like hail, which turned to snow in about 14 or 15 hours, which fell in such abun- 

 dance for an hour, that the streets and tops of the houses were quite co- 

 vered ; and a little more after mid-day, which continued all the remainder of 

 the day. 



On the 1 8th there were no sensible shocks of the earthquake, but now and 

 then visible undulations of the ground, though of no consequence. 



The igth in the morning, at sun-rise, there were between the east and south 

 certain clouds very thick, which dispersed as they came nearer to the solar 

 disk ; but there always remained a particular uncommon whitish thickness in 

 the air, till l6 hours, when it was entirely dissipated. At IS-f hrs. was heard a 

 rumbling noise, the house began to shake, and the motion continued 8 or 10 

 seconds: it came like a blow, and the house waved from west to east. At ig 

 hours exactly, followed another shock, which lasted about 3 seconds. All the 

 remainder of the day, quite till 23 hours, the earth was in continual motion; 

 and exactly at 23 hours followed another shock, like that at I84-. At 2 hours, 

 and at 3-|-, and 3 hours 50 minutes, were 3 small shocks ; and from that time 

 to the 20th of January at 234- hours, nothing was felt : at this hour there was 

 a small shuddering, which was not universally observed. At 5 hours 25 mi- 

 nutes in the night, followed a shock like that of 184^ hours of the 19th day, 

 with this difference only, that the house waved from south-east, and continued 

 between 10 and 12 seconds; there followed a strong undulation of the ground 

 till 21 hours of Jan. 21 ; at 23 hours of the said day, a small motion of the 

 ground was observed by many. 



Some fishermen told him, that at the same hour on the 19th day of January, 

 that they had the terrible shock at Leghorn, they, being at sea between Me- 

 loria and Gergona, saw a small part of the sea rage violently, and raise itself to 

 a great height in a white foam, with a dreadful roaring, which frightened them 

 so far as to imagine themselves lost, though it did not directly beat upon them, 

 but they felt it on one side only ; which made them imagine some violent mis- 

 chance at shore ; and keeping their eyes always on that troubled part of the 

 sea, perceived it made towards Leghorn, and broke on the old fortress, which 

 for a little while was hidden from them. The captain of a ship, who came to 

 this port, says, that he saw, to his great surprize, a few miles distant from 

 Capo Corso, several streams running with great impetuosity different ways, and
