"On returning to England, after his first great journey of discovery, he and Mrs. Livingstone stayed in my house for some time, and I had frequent conversations with him on subjects connected with his African life, especially on such as related to natural history and medicine, on which he had gathered a fund of information. His observation of malarious diseases, and the methods of treatment adopted by both the natives and Europeans, had led him to form very definite and decided views, especially in reference to the use of purgatives, preliminary to, and in conjunction with, quinine and other acknowledged febrifuge medicines. He had, while staying with me, one of those febrile attacks to which persons who have once suffered from malarious disease are so liable, and I could not fail to remark his sensible observations thereon, and his judicious management of his sickness. He had a great natural predilection for medical science, and always took great interest in all that related to the profession. I endeavored to persuade him to commit to writing the results of his medical observations and experience among the natives of Africa, but he was too much occupied with the preparation of his Journal for the press to enable him to do this. Moreover, as he often said, writing was a great drudgery to him. He, however, attended with me the meetings of some of the medical societies, and gave some verbal accounts of his medical experience which greatly interested his audience. His remarks on climates, food, and customs of the natives, in reference to the origin and spread of disease, evinced the same acuteness of observation which characterized all the records of his life. He specially commented on the absence of consumption and all forms of tubercular disease among the natives, and connected this with their constant exposure and out-of-door life. "After leaving my house he had lodgings in Chelsea, and used frequently to come and spend the Sunday afternoon with my family, often bringing his sister, who was staying with him, and his two elder children. It was beautiful to observe how thoroughly he enjoyed domestic life and the society of children, how strong was his attachment to his own family after his long and frequent separations from them, and how entirely he had retained his simplicity of character.
