or banyan days
Those in which no flesh-meat is issued to the messes. It is obvious that they are a remnant of the maigre days of the Roman Catholics, who deem it a mortal sin to eat flesh on certain days. Stock-fish used to be served out, till it was found to promote scurvy. The term is derived from a religious sect in the East, who, believing in metempsychosis, eat of no creature endued with life.
