During the intervals of the obfervations made with 
the quadrant, the planet was always obferved to be 
perfectly round, without any ring or nebulofity.. 
It may, at firft fight, feem wonderful, fays Signor 
Zanotti, that obfervations made with different tele- 
fcopes, one of 10, the other of 22 feet, fhould fo 
nearly coincide, the times of the firft contact agreeing 
to the fame fecond, and thofe of the laft differing 
only 7 feconds, by which the contaft was feen to 
, happen fo much later through the longer telefcope ; 
and the blame might be laid either upon the longer 
telefcope, or upon the obferver. The goodnefs of 
the telefcope will readily be allowed, when it is 
known, that it was made by Campanij and he lki 1 
and dexterity of the obferver are too well known, to 
give room for any fufpicion on his part. It may ra- 
ther be attributed to the near equality of the magni- 
fying power of the two inftruments; the longer tc- 
lefcope having an eye-glafs of 3 inches focal length, 
and the fhorter an eye-glafs of 14 ; by means of 
which.
