No alteration in the Constitution shall be made, unless the same shall
have been proposed at a Stated Meeting of the Society, held not less
than three months previous to the adoption of such alteration; and
no such amendment shall be adopted unless approved by the votes of
three-fourths of the members present.
The Secretary shall state on the notices of that meeting that an
amendment or amendments to the Constitution will be acted upon. All
other questions shall be decided, when there is a division, by a
majority of votes; in those where the Society is equally divided, the
presiding officer shall have the casting vote.
