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 

 bifee"ted by the vilible horizon: I have therefore 

 recomputed the time, by allowing for the dip and 

 refraction, which, together, amount to 8'. This 

 correction makes the apparent time of the beginning 1 

 6 h 5 1 7 12 , and the end 8 h o' 37"; hence the du- 

 ration of the eclipfe was i h 9/ 25"; but, by a care- 

 ful computation from Mayer's new Tables, the du- 

 ration fhould have been i h 13' 20"!, which is al- 

 moft about 4/ longer than the obfervation affords > 

 but, as it is remarked that the beginning was not 

 exactly taken, and the Moon entering very obliquely 

 on the Sun, the defect in 4/ would be but little. It 

 feems moil 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
