I was delighted to find this here; an original copy resides in the master section in Cardiff and I never got the chance to view it. Ill enjoy reading it here.
Bill Nye (Name he wrote under) wrote and illustrated extensively for punch and at one time was summoned to Queen Victoria as she was amused.
Unfortunately Bill's work was within government and his admission to this writing was felt to be; well better to kindly decline the invite; hence his reference to disguises and moustaches in the first few paragraphs.
Well thatís as I was told the tale, who knows.
