W. M. N. is thanked for the kindly spirit of his communication. The articles to which he refers shall be attended to.

AMERICA. Our friends who desire to know how "N. & Q." may be forwarded to America are informed that all that is required is to affix a penny stamp to a copy of the stamped edition.

SALOPIAN. There is as little doubt that Friday is considered unlucky because it is the day of the Crucifixion, as that the belief of its being unlucky for thirteen to set down to a meal together owes its origin to the remembrance of the Last Supper.

G.R.E.E.N. is no doubt a wag. But as we do not share his viridity, we have committed his communication to the fire, and can assure him for his consolation that, like Sir Andrew Aguecheek's leg, it looked "indifferent well in a flame-coloured stock."

F. M. W. (Camden Town), who inquires respecting the meaning and origin of "era," is referred to our 4th Vol. pp. 383. 454., and 5th Vol. p. 106.

K. (of Carlisle). This correspondent has not said what the communication was to which he refers. We are therefore unable to reply to his inquiry.
