An infantry regiment of the line was embarked at Kingstown in a very capacious steamer, I believe the Medusa, for Gibraltar or Malta. There was a large quantity of baggage which the men were actively engaged in conveying on board and stowing away. I was sauntering on the jetty when, at one o'clock, they were directed "to knock off for dinner." The meal was served on deck, and consisted of soup, bread, and meat, and the recipients availed themselves of every position in which they could speedily enjoy their repast. The circular seat around the window on the quarter-deck was fully occupied. The soup was brought up in large tin basins, and the bread was amply supplied, ready cut, from wicker baskets. One of the men who occupied the circular seat, seeing a basket of bread placed almost within his reach, stood up, advanced about a yard, and having procured what he required, stepped backward to resume his place. Meanwhile, one of the attendants had placed a large vessel of soup on the portion of the bench apparently vacant, and the soldier sat down in it. With a loud scream, indicative of acute pain, he rushed to the tafferel, and plunged into the sea. He was immediately rescued from the risk of drowning, and having been brought on board, was sent below for medical treatment, and to get his wet clothes changed. I saw him on deck in the course of the afternoon, and he stated that he was suffering very little, and that he would be "all right" very soon. Unless the temperature of the soup was below scalding heat, the instantaneous application of the cold water, although of a saline character, must have been extremely efficacious.
