§ 39. Record of ordinances. Every ordinance shall, upon its taking
effect as herein provided, be recorded in a book kept for that purpose
by the clerk. Such records shall include the signature of the president,
attestation of the clerk and the mayor's written approval, or in case of
his disapproval a memorandum of its passage over his veto; or in case
the ordinance took effect because he failed to approve or disapprove and
return within ten days, then a memorandum to that effect. Such record or
a certified copy thereof, shall be presumptive evidence of the passage
of the ordinance and of the facts certified. The original engrossed
ordinances for each year shall be bound together and kept in the custody
of the clerk.
