ἐν γὰρ τοῖς τέσσαρσιν ἔτεσι μιᾷ ἡμέρᾳ ὑστεροῦσι παρὰ τὸν ἥλιον, ἐν δὲ τοῖς μ′ ἔτεσι δέκα ἡμέραις ὑστερήσουσι παρὰ τὸν τοῦ ἡλίου ἐνιαυτόν, ὥςτε καὶ τοσαύταις ἡμέραις ἀναποδίσουσιν αἱ ἑορταὶ πρὸς τὸ 〈μὴ〉 γίνεσθαι κατὰ τὰς αὐτὰς ὥρας τοῦ ἐνιαυτοῦ. ἐν δὲ τοῖς ρκ′ ἔτεσι μηνιαῖον ἔσται τὸ παράλλαγμα καὶ πρὸς τὸν τοῦ ἡλίου ἐνιαυτὸν καὶ πρὸς τὰς κατὰ τὸ ἔτος ὥρας.
