VOL. LXXVII.] PHILOSOPHICAL TRANSACTIONS. 177 



On Mr^M.'s arrival at Penrith in the evening, every one there spoke of it as 

 having been sensibly felt in that town. The next day, pursuing his journey, he 

 was informed it had been felt along the banks of Ulswater, in Patterdale, at 

 Ambleside, along the side of Winander Meer, and particularly at the house in 

 the island on that lake, the property of Mr. Christian. At Castle-Head, the 

 lady of the house, and some of the servants, were awakened by it, and describe 

 it as shaking violently the beds, the chairs in the rooms, and the sashes of the 

 windows. At Cartmeal, a town about 5 miles from hence, it was also felt very 

 severely ; and at the village of Carke, 1 miles from Cartmeal, a gentleman states 

 that he was awake some time before the shock ; that he first heard a rumbling 

 noise, like a carriage at a distance, and was considering what carriage could be 

 moving at that hour, when he felt the shock. The noise continued some time 

 after the shock was over; and he thinks the whole might last about 4 or 5 

 seconds, and it seemed to travel from the east to the westward. Almost every 

 body in the neighbourhood of Carke and Cartmeal were awakened by it, and 

 some persons much alarmed. At Lancaster, about 10 miles east of Cartmeal, it 

 was very plainly felt, particularly in the great tower of the castle. It appears to 

 have extended as far as Manchester, where it was slightly perceived. 



FIl. Determination of the Heliocentric Longitude of the Descending Node of 

 Saturn. By Thomas Bugge. p. 37. 



The culmination of Saturn was observed with a 6-feet achromatic transit-in- 

 strument, and the planet compared with o and n of Sagittarius, whose apparent 

 right-ascensions in the middle of August 1784 were 282° 56' 34'' and 284° 14' 

 33". The meridian altitude was observed with a 6-feet mural quadrant. From 

 the observations are calculated the right-ascension and declination, the geocentric 

 longitude and latitude, of Saturn, which are to be depended on to 4 or 6 seconds. 

 Those observed longitudes and latitudes are compared with the tables of Dr. 

 Halley and of M. de la Lande. In the errors of the tables -f- signifies that the 

 longitude of the tables is less than the observed longitude ; and the meaning of — 

 is, that the calculated longitude is greater than the observed. It ought to be ob- 

 served, that the heliocentric longitudes of Dr. Halley 's tables have been corrected 

 for the perturbations after the principles of M. Lambert (Memoires de Berlin, 

 pour 1783, p. 2l6, and Collection des Tables Astronomiques de Berlin, torn. 2, 

 p. 269.)
