Abstract
THE first of the new series of technical publications issued by the Royal Geographical Society is an exhaustive investigation of map projections based upon Airy's idea of making the mean square scale error a minimum. This principle was applied by Airy to zenithal projections as affording a reasonable compromise between the stereographic projection and the projection of equal area. Mr. Young shows how the arbitrary constants in Airy's solution should really be determined, and then proceeds to compare the minimum error projection with others belonging to the zenithal class. The conclusion reached is incorporated in a recommendation to cartographers to use the equidistant projection with total area true as being the best zenithal projection for all cases, except when some specially desired feature necessitates a different projection.
