=Imperforate cervix vesicæ.= A case reported by Lapotre, in a calf, had no cervix, and the ureters were blocked by pea-shaped nodules. =Recto-vesical fistula.= In a calf 13 days old the rectum opened into the bladder and the fæces and urine escaped by a pervious urachus. (Kaufmann and Blanc). URETHRAL ANOMALIES. _Imperforations._ In the new born male, foal, lamb, etc. Usually at the outer end, and it may be for some distance back. In one case the sheath was firmly adherent on the wall of the abdomen, thus shutting off all exit of urine. If the canal is absent only at the orifice or for a short distance, the urethra beyond this can be felt full of liquid and fluctuating. The patient being properly fixed a fine trochar is pushed from the end of the penis into the blind end of the urethra, which will be ascertained by the overcoming of resistance. The trochar is now withdrawn and the urine flows through the cannula. A catheter or sound is now tied in the passage to maintain it pervious until cicatrization shall have taken place. _Hypospadias._ Short urethra opening backward on the lower surface of the penis. Considered irremediable. _Epispadias._ Urethra opening on the upper surface of the penis. Much more rare. ACUTE URETHRITIS. CATARRH OF THE URETHRA. This occurs in all genera of domestic animals, and may be either acute or chronic. It is most common in the entire males, not only because of infections sustained in copulation, but because frequent erection exposes the opening of the urethra to injury and inflammation, and to the entrance of pathogenic germs. _Symptoms._ Pruritus of the penis, and difficulty and pain in urination and straining are frequent, but a single small jet may be all that is passed at a time. The papilla on the end of the penis is red and angry and somewhat swollen. Later a few drops of muco-purulent fluid may be pressed from the orifice. In the bull, dog and boar this oozes from the retracted penis into the sheath, so that a collection is found in that canal, and the mucosa becomes infected causing a balanitis. The infection may be conveyed from male to female and _vice versa_. Dr. Horand of Lyons even found that the muco-purulent discharge of gonorrhœa in man caused an urethral catarrh in the dog, which however did not persist for any great length of time. _Diagnosis_ is based on frequent and painful urination in jets, tenderness of the urethra under palpation or catheterization, redness and swelling round the urethral orifice, and the oozing of pus. In the absence of any external injury one should always ascertain if cystitis is present. _Prognosis_ is favorable under appropriate treatment. Spontaneous recovery will usually occur early.
