Summary:
Thanks WALM for having sent interesting publications, especially the one on relation of structure of man to lower animals,
and just a few days since, on protuberances on bird skulls. WALM’s facts on the latter subject have an important bearing on the acquisition of sexual characters. CD is pleased that the influence of sexual selection is admitted.
