The crowds were now at about 1500 and on this day, for the first time, a priest was among them. During the night something strange had happened and there was an atmosphere of excitement - though Bernadette seemed only aware, as usual, of the Lady she ran to the grotto to meet. She conversed with the Lady and continued her acts of penance.
A pregnant housewife Catherine Latapie had gone to the spring Bernadette had dug days before with the idea that bathing her arm, which had a paralysis of the ulnar nerve and caused her a great deal of pain, might soothe the agony. Her arm was healed and from that time forward caused her no pain. She also went into labour immediately and had to leave the grotto after which her baby was safely delivered. Dr Dozous, the local and esteemed M.D. was interested in this event and began recording the events at the spring which had medical implications. This is often recorded as the first miracle.
