Then looking constantly with a carefull eye upon the water in the Globe, which by reason of the transparency of the Crystal was plainly seen to be yet altogether fluid and clear, the water, though now out of the Ice, did by the operation of the introduced cold, (after it had attained to its due point with a swiftness imperceptible to the Eye, the transparency within the Globular part being lost, and itself in an instant, as 'twere, deprived of its motion) totally conglaciate.

Conjunctionem, à Limbo Lunæ inferiori ad 4', vel, minimum, 3' minuta; sic ut nulla eo tempore Occultatio, sed tantum arduus Transitus est erit. Volupe profecto erat jucundissimum illud spectaculum, de die, Soleque splendente, adeò distinctè ac dilucidè contemplari. Luna namque erat tenuissima, ad Conjunctionem propendens, valdeque Corniculata: At Venus prope modum plena, & corpore valde diminuta.

Octobris nullà ratione amplius Sextante observari à me potuerit; licet omnem adhibuerim diligentiam. Nam vix ac ne vix quidem nudo oculo animadversi potuit, adeò ut ab hac die illam amplius non viderim, ut ut singulis diebus Calo serenissimo omnes oculorum nervos ad eam intenderim. Altera verò Nova in Collo Ceti ad medium usque mensis Octobris, Mandibulae Ceti aqualis ferè extitit magnitudine, & claritate eam propemodum superavit; adeò ut hoc Anno Secundæ fuit magnitudinis, ac major quam praecedentibus annis, excepto Anno 1660, quo major etiam Mandibulae Ceti à me fuit deprehensa. Aliis temporibus non memini eam Tertiæ Magnitudinis Stellas superasse.
