SIR, 
BY the Ruly Man of War, in Decemkr laft, I gave 
you the beft Account I could of the Comet that 
appeared here in Oiloler ; but the Weather at that 
time was often Cloudy : I had no Inftruments nor Cele- 
ftial Globe, and am not perfedly acquainted with the •

was but indifferent. 
Now having no Acquaintance with any of the Royal 
Society^ I have fome other Remarks to make to you, 
which I refer to you to acquaint fome of them with, 
or nor, as you think it may be worth their Notice. 
When I came from England^ I caufid my Barometer 
(which had wrought very well in England fome Years) 
to be carefully put up, with intent to try if the Air had 
the fame Effeft on the 5 here as in England; but by 
fome Misfortune, when I came to take it out my Tube 
was broken, and I could never procure another till about 
Chriftmas hfl: ; then I met with one of 36 Inches, and 
cleanfed all my Frame and the Tube very well, put my 
5 through double Cloth, and made that Fine, and Cet it 
up with all the Exaftnefs I could ; when it was firft ia 
the Ciftern the ? ftood one degree below Changeable ; 
I diligently obftrved it every day, and found that in the 
Mornings before the 0 arofe it would be there; and as the 
Heat encreafed with the Day, it funk to within oae De-
