Note 57 — Chapter IV · ToC
Reading edition
This ornament was used in one or two processions when the Holy Eucharist was carried. The "burrall" is the glass in the middle wherein the Sacrament was placed. Only rich churches possessed this ornament, which was of very late introduction. It is needless to add that the still more modern service of Benediction of the Blessed Sacrament was never in use in England.
