We have already mentioned that the names of the a year is
lunar stations are, by the names of the months, divided over^by that
into groups, each month having a namesake in the cor- which the
responding group of stations.    We have represented risii^g^of
these things in a table, in order to facilitate the subject occ'ur.s.^
(v. i. 218).    Knowing the station in which the heliacal
rising of Jupiter occurs, and looking up this station
in the just-mentioned table, you find at the left of it
the name of the month which rules over the year in
question.    You bring the year in connection with the
month, and say, e.g. the year of Gctitra, the year of Vai-
