Excerpt from A Practical Treatise on the Diseases, Injuries and Malformations of the Urinary Bladder, the Prostate Gland, and the Urethra A new edition of this work having been called for, after having been out of print for several years, I have entrusted its revision to my son, Dr. S. W. Gross, who has rewritten the greater portion of it, and brought it fully up to the existing state of our knowledge. As he has delivered several courses of lectures upon the affections of the urinary organs in the Jeffer son Medical College, and has devoted much study and attention to their practical details, I felt satisfied that the task would be thoroughly executed. The chapters on Tumors of the Bladder and of the Prostate Gland, which add largely to the value of the work, are entirely due to his pen. It is proper to observe that the anatomy of the urinary organs, and the appendix in relation to the prevalence of stone in the bladder and calculous disorders in the United States, inserted into the former editions, have been omitted in this. To Dr. C. H. Mastin, of Mobile, Alabama, I am indebted for the statistics of lithotomy as performed by American surgeons; and I am also under obliga tions to Dr. Barnes, surgeon-general U. S. Army, for several engravings illustrative of various topics discussed in these pages. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
