A Mad Ox on the Loose in the Street– About twelve o’clock yesterday as a large black ox was being driven to the market, he broke loose from his drivers and went tearing down St Joseph Street, driving the passengers by right and left. Opposite St Margaret he encountered a woman and knocked her down.  He then went on to Longueil Lane, where a little boy who was crossing the street was caught between his horns and knocked down.  A gentleman who was passing along helped the boy up.  The poor little fellow’s face was quite black and blood was coming out of his mouth.  Dr Tracy was sent for and the boy soon got better.  The ox went on his way down McGill Street.  No further accidents have been heard from, but several people had very narrow escapes.
