t-hand side, bearing
the same number. For example: the question is about the occurrence of a
Sunday of the first class and a Double of the first class. _Double of
the first class_ stands first word of page, and _Sunday of first class_
will be found in column beneath the rows of figures. Now the square in
which straight lines drawn from _double of first class_ and _Sunday of
first class_ meet bears the number 6, and reference to number 6 in
column of directions found on same page gives the rule, "_Officium de 2,
Translatio de I_," that is, the office must be of the Sunday of first
class and the double of the first class must be transferred according to
the rubrics. When in these brief directive notes, (1-8), mention is made
of the "first or the preceding," the reference is made to feast or
office printed in the upper part of the Table, e.g., Double of first
class. Reference to "the second" or "following" refers to feast printed
in the lower section of the Table. Where _O_ stands in a square in the
_Tabella_ it signifies that there can be no occurrence or concurrence
between feasts whose "lines" meet in that square. These two tables are
very ingeniously arranged. The lists, given in the Breviary following
these tables, give the lists of greater Sundays and Ferias, privileged
vigils, doubles of first and second class and greater doubles, and tell
whether feasts are primary or secondary.

TITLE XII.--THE ARRANGEMENT OF THE OFFICE ACCORDING
TO THE RUBRICS GIVEN ABOVE.

If any one wish from the rubrics given in the Breviary to arrange the
office, he can see in the calendar and in the tables of movable feasts
which office he is to say on the following day. And when he has found
out the feast he determines, from the rules given, the vespers and the
other hours.

If the office be the office of an excepted feast, the whole office is
said from the feast as it is in the Proper or Common of saints; but the
psalms of Lauds and the hours are taken from the Sunday psalms, as they
stand in the new Psaltery, At Prime the psalm _Deus in nomine_ is said
in place of _Confitemini_. Compline is said from the Sunday psalms. If
the office be the ordinary non-excepted office it is recited according
to the rule laid down in the new rubrics. Tit. I., n. 5,:--
