disappeared in the Bull’s back. The mod condenfed part of 
it was towards the middle in n ; Sometimes it aflumed this 
form and Sometimes that of an arch. The phaenome- 
uon laded about three-quarters of an hour, and Seemed not to 
have gone out of the zodiac, though when it disappeared, it 
was more to the South than when 1 fird Saw it. The air was 
cold, but not frofty. Towards midnight an aurora borealis 
was Seen in the north, which appeared Something like the phe- 
nomenon jud mentioned ; I did not fee it. 
March 15, 1774, at about 7I o’clock in the evening, a 
column of light appeared in the north, Something like that of 
yederday ; weather very fine. 
At Louvain, 1775, April 19, ph. 30', at night, after a 
dorm, I Saw a bright white line of light one or two degrees in 
breadth extending from N.N.E. through N. to N.W. almod 
parallel to the horizon, and elevated about 9 degrees. It was 
brighter in the center, and dars of the third and fourth mag- 
nitude which it covered were much diminiflied in brightnefs ; 
it Sometimes rapidly vanilhed and re-appeared, and altogether 
laded near half an hour. 
Wickhill in Gloucederfhire, 1777, Feb. 26, at about 7 h. 
at night, I Saw a faint white trail of light, not unlike a foggy 
column, about 6 or 8 degrees in breadth. It extended from the 
horizon W. by S. to E. by S. pafiing over the dars in Orion’s 
feet, and a very little to the north ot Sirius. It teemed to 
have no motion, or to alter in brightnefs. The air was rather 
foggy, with a few clouds and a little wind. At about 10 
o’clock a dight aurora borealis appeared in the north with 
dreaks, extending Sometimes to the zenith.
