Let A, B, C, D, (Fig. 44,) represent the earth in dif-ferent parts of its orbit; J, Jupiter in his orbit sur-rounded by his four satellites the orbits of which aremarked 1, 2, 3, 4. At a the first satellite enters theshadow of the planet, and emerges from it at b, and ad-vances to its greatest elongation at c. The other satellitestraverse the shadow in a similar manner. These ap-pearances will be modified by the place the earth hap-pens to occupy in its orbit, being greatly altered by per-spective ; but their appearances for any given night asexhibited at Greenwich, are calculated and accuratelylaid down in the Nautical Almanac. When one of the satellites is passing between Jupiterand the sun it casts its shadow on the primary as the 245. Describe the phenomena of the eclipses from figure these appearances be affected by the relative position ofthe earth, with respect to the planet ? Does the shadow of asatellite or the satellite itself ever make a transit across thedisk of th
