In 1906, Nevil Maskelyne edited the first issue of The Magic Circular, the society’s magazine, and on its cover were the signs of the zodiac, together with the words “Indocilis Privata Loqui”. The Latin motto is roughly and some say inaccurately translated, as “not apt to disclose secrets” – and any member who does so may be expelled. Over the years the logo has evolved into the one you see here. Many of our 1,500 members are proud to use the logo in their publicity material and it adorns several products sold to the public.
