In 1868 Sir Geroge Biddell Airy published a paper in the Monthly Notices of the Royal Astronomical Society setting forth plans he and the Hydrographer of the Navy had developed for the British ToV expeditions of 1874 and 1882. It is those plans, and this and similar maps which Richard Proctor attacked. Note the possible Canadian ToV observaing stations on the map.
