As soon as the Electors were dress'd they return'd to the Assembly-Room, and then went with the Ambassadors of the other Electors from the Town-House to the Square, where they found Horses sumptuously caparison'd, which they mounted, and thus rode in Cavalcade to St. _Bartholomew_'s Church. The three Electors rode first in one Row bare-headed. The four Ambassadors of the absent Electors rode next, according to the Rank of their Masters. Their Electoral Highnesses and the Ambassadors were receiv'd at the Door of the Church by the Bishop of _Neustadt_ at the Head of the Chapter, who conducted them into the Choir, where they plac'd themselves, according to their Rank, in the Stalls of the Canons, which were lin'd with Velvet and Gold-Lace. The Elector of _Triers_ sate by himself opposite to the Altar, where a Praying-Desk and an Arm-Chair were set up for him, which were lin'd also with Crimson-Velvet.
When all the Company were seated, the Bishop of _Neustadt_ began the Mass. At the first Consecration, the Ambassadors of the Protestant Electors went into the Chappel of the Conclave which joins to the Choir: After the Elevation of the Host they return'd to their Places, where they remain'd during the rest of the Office, and then the Electors and Ambassadors all went up to the Altar. The Elector of _Mentz_ was in the middle between the Elector of _Triers_ on his Right and the Elector-Palatine on his Left. The Ambassadors were in the same Row, according to their Rank, on the Right and Left of the Electors. The Elector of _Mentz_ took the Book of the Gospels and laid his Right Hand upon it, as did also the Electors that were present, and the Ambassadors of those who were absent, and then took the customary Oath to elect no Person for Emperor but one that they should think in Conscience to be most qualify'd. After having taken the Oath they went into the Chapel of the Conclave, where they were shut up near three Hours. Then they return'd into the Church and plac'd themselves in a Gallery erected over the Grate that separates the Choir from the Nave, which was lin'd with Scarlet Cloth and hung with Tapestry, and had seven Arm-Chairs plac'd in it of red Velvet, adorn'd with Lace and Fringe of Gold. The Electors and Ambassadors being seated, the Chancellor of _Mentz_ read aloud the Act which had been just drawn up in the Conclave, whereby CHARLES King of the _Romans_, and of _Spain_, was proclaim'd Emperor. Then the whole Church resounded with great Shouts of _Long live the Emperor_! And at the same instant the Cannon was fir'd from the Ramparts, and the Burghers and the Garison made three Discharges of their small Arms.
