may I^e, and to leave no doubt in regard to the obfervations, 

 1 have again examined them ; and in fome places which 

 were rather i.ncenain, and which I employed in my firft 

 calciilaiions, 1 rubliituled others. I have alio made an al- 

 lowance for the deviation of the inftruments, and em- 

 ploved'all thofe precautions which are ufual when great 

 prcciUnn is required. The refiilt of all thefe has been only 

 a fniall diflcrence in fome of the right afcenfions, which 

 can have litde or no influence on the ultimate refults of 

 the calculation, and for which rcalon I did not think 

 great exaclnefs neceflary in the firft reduAions. Accord- 

 ing to this laft rigorous examination, I'jj'' are to be de- 

 ducted from the firft; four right afcenfions, and 1*5" to be 

 added to thofe of the loth, nth, 14th, 19th, 2ift, 23d, 

 28th, 30th, and 31ft of January, and the ift of February; 

 and 3" muft be taken from thofe of the 5th and 8th of Fe- 

 bruary. With the tranfit inftrument the obfervations were 

 made, different times, with all the five threads j and thefe I 

 always preferred to thofe made with the circle. I ufed thofe 

 by the circle when I failed with the tranfit inftrument ; as 

 on the firft four days; and on the 13th of January, when the 

 obfervations were not made with all the five thread?, I took 

 a mean of the obfervations made with the circle, and another 

 of thofe made with the tranfit inftrument. The diff'crencc 

 between thofe with the former inftrument and thofe with the 

 latter, was never greater than 0*2 in time, except on the 

 19th of Januarv, when T found 1" in time mote by the 

 circle. In regard to the declinations, I have found no cor- 

 reftions to be made. Should any aftronomer, for his greater 

 fatisfaftiou, be defirous to fee the original obfervations, I 

 lliall he happy to communicate them to him. They will be 

 publifiied in the fixth book of the Specola JJJironomtca, toge- 

 ther with all my other obfervations made fipce 1794.
