The speciality of Sonnenschein and Allen's Royal Relief Atlas (W.

Swan Sonnenschein and Allen) is sufficiently indicated by its title. It contains thirty-one excellent maps of the principal countries of the world, in which the mountains and elevated districts are represented by relief. There can be no doubt that this will give a sense of reality to the learner. We hope, too, that it may fulfil the publishers' idea of having a special utility for the blind. The idea is a good one, and deserves success.
