The said Communion to be Administered at such Times, and with such Limitation as is specified in the Book of Common Prayer; provided, that no such Limitation by any Construction shall be allowed of, but that all Deans, Wardens, Masters or Heads of Cathedral and Collegiate Churches, Prebendaries, Canons, Vicars, Petty Canons, Singing-Men, and all others of the Foundation, shall receive the Communion Four Times Yearly at the least.
