Again, on the 18th Day there will be an Immersion at 2 h. 55 m. in the Afternoon, and at 3 h. 48 m. the Emission will happen. Again, on the 4th of February, at 9 h. 31 m. in the Morning, the fourth Satellite will Immerge into the Shadow of Jupiter, and at 9 h. 44 m. the same Morning, it will Emerge out of the Shadow. And after this Time, the fourth Satellite will pass wide of the Shadow till the 24th Day of June 1740; when the Immersion will happen at 8 h. 43 m. in the Evening, and the Emission at 10 h. 15 m. the same Evening.
