Article I, Section 3, Clause 5

The third section further provides, that the senate shall choose their own officers. This is so congenial with the constitution of our own state, that I need not advance any argument to induce the free citizens of Massachusetts to approbate it.

Cites "The third section" for the provision that the senate shall choose its officers, which is this clause.

The Senate ſhall chooſe their other officers, and alſo a Preſident pro tempore, in the abſence of the Vice-Preſident, or when ••e ſhall exerciſe the office of Preſident of the United States.

The paragraph prints Article I, Section 3, Clause 5 of the Constitution as signed; the quoted words are the same as the clause's (apart from capitals and the long s), though the pamphlet's punctuation differs in places.
