The two distinct penises of normal size were apparently well formed and were placed side by side, each attached at its root to the symphysis.

Their covering of skin was common as far as the base of the glans; at this point they seemed distinct and perfect, but the meatus of the left was imperforate.

The right meatus was normal, and through it most of the urine passed, though some always dribbled through an opening in the perineum at a point where the root of the scrotum should have been.
