Late studies in the Psychology of Sex have led to some interesting speculations with regard to the poet Shelley; the author writes a few lines by way of introduction to the following paper by the author’s friend, which puts very clearly, as the author thinks, some points in Shelley’s temperament which have hitherto been neglected or misunderstood, and which call for renowned consideration.

Not having author himself made a special study of the Modern Psychology, the author does not pretend to certify to the absolute truth of the theories put forward by the author, but he does certainly think, after due consideration, that they are worthy of very careful study.
