Observations of the vernal equinox made at the Paris Observatory (l'observatoire royal) on 21 March 1703 and notes on earlier equinoxes and the implications for year length and calendar reform, written on a gathering that has been removed from a larger manuscript (18th-century (?) foliation 81-90, 19th-century pencil pagination 301-319). A note in a contemporary Italian hand attributes the manuscript to Cassini and records that it was sent from Paris in May (f. 1r).
