settling or inflating any person in a dignity. The word is derived from the Latin in, and flatus, a term used for a seat in church, in the choir, or a seat or bench in a court of justice, &c.; though Voetius is of opinion the word is of German origin.

Installment is chiefly used for the induction of a dean, prebendary, or other ecclesiastical dignitary, into the possession of his stall, or proper seat, in the cathedral church to which he belongs. This is sometimes also called infallation.

Installment is likewise used for the ceremony, whereby the knights of the Garter are placed in their rank, in the chapel of St George at Windsor.
