Hevelius deduxit latitudinem comet* 8st. 74'. Sed fculptor viam
comet* fub finem motus ejus irregulariter incürvavit, & Hevelius
in fchemate obfervationum Auzoutii a fe conftrufto incurvationem

Vifus edam fuit hie cometa Martii die 9, & tunc locari debuit

Apparuit hie cometa menfes tres, fignaque fere fex defcripfit, &
uno die gradus fere viginti confecit. Curfus ejus a circulo maximo
plurimum deflexit, in boreatn incurvatus ; & motus ejus fub finem
ex retrogrado faCtus eft direftus. Et non obftante curfu tam in-
folito, theoria a principio ad finem cum obfervationibus non minus
accurate congruit, quam theori* planetarum cum eorum obfervationibus
congruere folent, ut infpicienti tabulam patebit. Subdu-
cenda tamen funt minuta duo prima circiter, ubi cometa velocif-
fimus fuit; id quod fiet auferendo duodecim minuta fecunda ab
