Provision and revision.

Explanation:

Every constitution as originally adopted or later amended con- tains provisions furnishing the means whereby it may be amended. ... Only the Constitution of New Hampshire omits to provide for specific amendment, although it does provide a method whereby a convention may be called for a general revision.

When more than one amendment shall be submitted at the same election, such amendments shall be so submitted as to enable the electors to vote on each amendment separately. One amendment of the constitution may revise any entire article, except the article on general provisions, and in revising any article, the article may be renumbered and all o r parts of other articles may be amended, or amended and transferred to the article being revised. Not more than five amendments shall be submitted at the same election.
