We have in this little work the translation by Dr. Allen, of two monographs written by Prof. Ultzmann, of the University of Vienna, upon two important subjects. If additional light can be thrown upon them, its value will be quickly appreciated by those who have found them difficult of diagnosis, and often intractible in management. The neurosis of the genito-urinary organs are very fully considered. Reflex influences receive especial attention. The diagnosis, prognosis and treatment of these affections will be found instructive to students and helpful in practice. The second monograph deals with sterility and impotence in the male. It is a valuable article. The volume is one of the "Ready Reference Series."
