Late studies in the Psychology of Sex have led to some interesting speculations with regard to the poet Shelley; and it is with pleasure that I write a few lines by way of introduction to the following paper by my friend, George Barnefield, which puts very clearly, as I think, some points in Shelley's temperament which have hitherto been neglected or misunderstood, and which call for renowned consideration.

Not having myself made a special study of the Modern Psychology, I do not pretend to certify to the absolute truth of the theories put forward by Mr. Barnefield, but I do certainly think, after due consideration, that they are worthy of very careful study.
