Gull was devoutly religious—on Fridays the children had fish and rice pudding for dinner; during Lent she wore black, and the Saints' days were carefully observed. As a young boy, William Gull attended a local day school with his elder sisters. Later, he attended another school in the same parish, kept by the local clergyman. William was a day-boy at this school until he was fifteen, at which age he became a boarder for two years. It was at this time that he first began to study Latin. The clergyman's teaching, however, seems to have been very limited; and at seventeen William announced that he would not go any longer. William now became a pupil-teacher in a school kept by a Mr. Abbott at Lewes, Sussex. He lived with the schoolmaster and his family, studying and teaching Latin and Greek. It was at this time that he became acquainted with Joseph Woods, the botanist, and formed an interest in looking for unusual plant life that would remain a lifelong pastime. His mother, meanwhile, had in 1832 moved to the parish of Beaumont, adjacent to Thorpe-le-Soken. After two years at Lewes, at the age of nineteen, William became restless and started to consider other careers, including working at sea. The local rector took an interest in William and proposed that he should resume his classical and other studies on alternate days at the rectory. William agreed, and would continue this routine for a year. On his days at home, he and his sisters would row down the estuary to the sea, watching the fishermen, and collecting wildlife specimens from the nets of the coastal dredgers. William would study and catalogue the specimens thus obtained, which he would study using whatever books as he could then procure. This seems to have awoken in him an interest in biological research that would serve him well in his later career in medicine. The wish to study medicine became the fixed desire of his life. Early career in medicine At about this time the local rector's uncle, Benjamin Harrison, the Treasurer of Guy's Hospital, was introduced to Gull and was impressed by his ability. He invited him to go to Guy's Hospital under his patronage and, in September 1837, the autumn before he was twenty-one, Gull left home and entered on his life's work. It was usual for students of medicine to conduct their studies
