Deinde, quod rarillimum, Jcvis ap-.. pareoteni Diamctrum in hac obscrvatione accuratiiJime ( ut mihi vidcor ) dimensi fiimus. Mcmini quidem me aliquoties Jovit Diametrum per Maculas Lunares observasse, eandem videlicet ad 5-5. plus minus accedcre; fed hac vice diameter Jovit longe extitit minor. Cognita enim rota Duratione hujus Occultationis 58' 10, atque data fimul Diametro Lunar x' 40, protinus innotelcit, ex ilia temporis Mora, cum scilicet primum Jupiter Limbo slio Lunx Limbum attingeret, & cum rurliis Occultaretur: ' id quod factum est spatio 55') Diameter Jovit, 30 ft'. a. At 2i-o/ si, the first Satellite was bid by the East Limb of A- Meo-. At 3 a' o'i-the East-fide.of the-fl/eow touched the West-side of Jupiter; then I took the Height of Jupiter, which was 8 01'. at 3h a' fj. At qfc-'-i' 57'. Jupiter Was inrirely hid by the Moon. It entered at equal Distance from the two Spots Grimalii and Arifiarckus; the last of which was in the Section of the Moon, which distinguish'd the Light from the Dark-part. At 31 5' '- the Second Satellite was hid by the East-side of the Moon. At 35' 48. the third Sa/W/te was hid. At 3b 56'. we. perceived by the Eye that Jupiter was parted from the obscure Side of the Moon.. M. De la Hire took the Height of Jupiter two Minutes after parting.
