Bulletin des sciences mathématiques
A French mathematics review journal issued from 1870 by Gauthier-Villars in Paris under the Ministère de l'éducation nationale, written for academic mathematicians and astronomers. Pages mix set type and formulae with fine line diagrams — labelled angles, shaded lattice regions, spherical triangles — plus an engraved publisher's device of a monogram in a laurel wreath with motto ribbon.
