made in the Auftrian Netherlands. 641 
The longitudes of the other obfervatories are affirmed, 
as fet down in the ConnoiJJance des Terns , 1777, as being 
well fettled. 
Twenty feconds were added to, or fubtr acted from, 
the obfervations of the fatellites made at Greenwich, 
with the fix-feet refiedtor, on account of the great and 
fuperior power of that inftrument. 
Although Jupiter’s fatellites obferved at Bruflels be 
emerfions only, neverthelefs, as they agree with what 
the aftronomers of the Academy of Sciences at Paris 
have done, as appears by the ConnoiJJance des Terns , the 
refult is well eftablifhed. 
Being defirous of affording every means of examining 
and forming a right judgement of thefe obfervations, I 
could not avoid faying thus much concerning them. It 
now remains for me to return you my thanks for the 
obliging communication of your obfervations. 
I am, 8cc.
