the College of Lewis the Great, where there was a 
pendulum clock, as I faid before, fet by a watch which- 
was regulated every day of obfervation.- 
I faw the comet the, 2d of April in the morning;, 
a little before four o’clock, about 4.°- above the hori- 
zon. The tail did not then appear" fo plain as the- 
day- before. Whether the twilight was ftronger, of" 
the horizon- more incumbered with vapours, 1 could* 
fee none of thofe colours in the tail which' Lhad ob- 
ferved’ the day before. I compared the nucleus in> 
the twilight with a fixed ftar which' was nearly in the 
fame parallel with the comet j it is the 2 2d of 
the firfi: table, and I judged it to be of the yth^ 
magnitude. 
The 3d, 4th, and 5th, I faw nothing of the comet ; 
but on tlie 6th in the morning I looked* for it through 
the telefcope, as it, was no longer vifible to the naked 
eye, from the great ftrength of the twilight at its 
.firffc rifing. 1 began to fee it at above a quarter after 
four, about 6° above the horizon. I compared the 
nucleus with a new ftar, which I have judged to 
be of the 7th magnitude. Its pofition at that time 
is let down in my firft table, N° 21. 
April 7, in* the morning, the fky not being per- 
fedlly clear, I faw the comet a little before four ; the 
appearances were not fo plain as for fome days paft. 
1 compared the nucleus with a new ftar which I jud^ 
to be of the 7th magnitude. The determination of 
this ftar may be feen in the firft table, N° 20, and 
that of the comet in the fecond. 
The 8th in the morning, the ftcy being almoft 
totally overcaft, I faw the comet for a few minutes 
through fome little intervals of the clouds, at near qt*" 
above
