ANOMALIES OF THE BLADDER.
Persistent urachus. Seen in the new born and mainly in males. Antiseptic closure is essential after having ascertained that the urethra is pervious.
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).
