Monsieur Bullialdus and Mr. Richelis account of the last Lunar Eclipse of January 1676 St. Novo; whereby it appears that the Rudolphine Tables or Hecker's calculus made thereon, do considerably differ from the Heavens both for duration and magnitude, but the Philolaic Tables, less. **Tabula Philolaica exhibent in Eclipsi visae Januarii die 1 mane, 1676.** | Uraniburgi | Parisis | Decemb 31. | St. novo. | |------------|---------|------------|-----------| | Initium | H. | 14. 53. 29 | 14. 13. 29 | | Max. obse. | 16. 0. 33 | 15. 20. 33 | Digitos III.
