40 ” Defcription of « Blaft-Furnace ‘ 
poffible to have been not feen by any perfon who was oat, 
# within the limits of the fenfible horizon which cireunt- 
fcribed it. This feems a ftrong prefumption that it mult 
have been uncommonly low shileed Very few ftars bemgy =. 
then vifible, it was not eafy to come to much accuracy a& . 
to its apparent path. 
Meteors have abounded Jately. I faw two very brilliant, 
but fmall ones, in one night, and within three minutes of 
time of each other; one between the Northern Crown and ; 
Bootes, and the other between the Crown and Hercules. - 
Fhe former appeared about the fize and brightnefs of Venus. 
And on the 2d, at about twenty minutes paft ten, another, 
which wasin the field of my night-telefeope with the comet :; 
befide many fmaller, ufually ealled Jfbooting flars. 
The laft time the weather has permitted me to fee the 
comet, was October 4, at twenty-five minutes paft ten, to @ 
very few minutes of its fetting. I thought its nucleus very 
difcernible, and the extent. of its coma rather increafed. 
From its then appearance I fhould hope, if the weather fa- 
vours, it will be traced down to its node; which feems likely 
to be in 17 or 18 of Sagittarius ; and that it may {till be 
Vifible for a fortnight from this time. 
I remain yours fincerely, 
CAPEL LOFFT. 
P.S. It is worthy of inquiry and obfervation, whether 
nearly all the very Jarge meteors have not been feen in or 
neat the magnetic meridian, as an acute and attentive phi-. 
kofophical obferver thinks to be the fact.
