w We were not certain of the inttant of the beginning of the eclipfe, from a little negligence ; but 
“ very certain of the end.” 
Remark. 
As the Sun’s altitudes are given, without any 
correction, I fuppofe they were taken by bring- 
ing down the image of the Sun, till it appeared 
bifedted by the vifible horizon : I have therefore 
recomputed the time, by allowing for the dip and 
refradtion, which, together, amount to S 7 . This 
corredtion makes the apparent time of the beginning 
6 h 51/ 12 77 , and the end 8 h o' 2?" > hence the du- 
ration of the eclipfe was i h 9' 2$" \ but, by a care- 
ful computation from Mayer’s new Tables, the du- 
ration fhould have been i h 13' 2o"'f, which is al- 
mod: about 4 7 longer than the obTervation affords - } 
but, as it is remarked that the beginning was not 
exadtly taken, and the Moon entering very obliquely 
on the Sun, the defedt in 4' would be but little. It 
feems mod reafonable to attribute the whole of the 
error to the beginning of the eclipfe. I have there- 
fore deduced the longitude from the end, and
