text: None of the proposals were accepted immediately, and many contemporary chemists found it too abstract to have any meaningful value. Of those chemists that proposed their categorizations, Mendeleev strove to back his work and promote his vision of periodicity, Meyer did not promote his work very actively, and Newlands did not make a single attempt to gain recognition abroad.
  Both Mendeleev and Meyer created their respective tables for their pedagogical needs; the difference between their tables is well explained by the fact that the two chemists sought to use a formalized system to solve different problems. Mendeleevs intent was to aid composition of his textbook, Foundations of Chemistry, whereas Meyer was rather concerned with presentation of theories. Mendeleevs predictions emerged outside of the pedagogical scope in the realm of journal science, while Meyer made no predictions at all and explicitly stated his table and his textbook it was contained in, Modern Theories, should not be used for prediction in order to make the point to his students to not make too many purely theoretically constructed projections.
  Mendeleev and Meyer differed in temperament, at least when it came to promotion of their respective works. Boldness of Mendeleevs predictions was noted by some contemporary chemists, however skeptical they may have been. Meyer referred to Mendeleevs "boldness" in an edition of Modern Theories, whereas Mendeleev mocked Meyers indecisiveness to predict in an edition of Foundations of Chemistry'.
