On returning to London, Livingstone devoted himself with special ardor to medical and scientific study. The church with which he was connected was that of the late Rev. Dr. Bennett, in Falcon Square. This led to his becoming intimate with Dr. Bennett's son, now the well-known J. Risdon Bennett, M.D., LL.D., F.R.S., and President of the Royal College of Physicians, London. The friendship continued during the whole of Dr. Livingstone's life. From some recollections with which Dr. Bennett has kindly furnished us we take the following: "My acquaintance with David Livingstone was through the London Missionary Society, when, having offered himself to that Society, he came to London to carry on those medical and other studies which he had commenced in Glasgow. From the first, I became deeply interested in his character, and ever after maintained a close friendship with him. I entertained toward him a sincere affection, and had the highest admiration of his endowments, both of mind and heart, and of his pure and noble devotion of all his powers to the highest purposes of life. One could not fail to be impressed with his simple, loving, Christian spirit, and the combined modest, unassuming, and self-reliant character of the man.

Of these deficiencies he was quite aware, and felt the importance of acquiring as much practical knowledge as possible during his stay in London. I was at that time physician to the Aldersgate Street Dispensary, and was lecturing at the Charing Cross Hospital on the practice of medicine, and thus was able to obtain for him free admission to hospital practice as well as attendance on my lectures and my practice at the dispensary. I think that I also obtained for him admission to the opthalmic hospital in Moorfields. With these sources of information open to him, he obtained a considerable acquaintance with the more ordinary forms of disease, both surgical and medical, and an amount of scientific and practical knowledge that could not fail to be of the greatest advantage to him in the distant regions to which he was going, away from all the resources of civilization. His letters to me, and indeed all the records of his eventful life, demonstrate how great to him was the value of the medical knowledge with which he entered on missionary life. There is abundant evidence that on various occasions his own life was preserved through his courageous
