Annot. in margine: Hoc non est retroagere, sed promovere. Repete totum pro 
cessum infra. Calculus Kepleri prodit anomaliam coaequatam 40° 23' et mediam 47° 39'. 
Addito apbelio 133° 28', prodit longitudo media anno 272. 18. Jan. liora 6 : 181° 7'; 
anno 1601: 316° 43', diff. 135° 36'; ex Prutenicis 132° 11 ', augmentum 3° 25'. 
Si ergo, pergit Keplerus, in annis 1872 adduntur motui, subtrahuntur ab eo me 
dio 3° 25', id est 205', quid subtrahetur in annis 1460? Resp. 160'. Correctio. Et 
si 1872 addunt aphelio 20°, quid 1460? 
Resp. 15. 32. - Corr. aplielii
