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 and sagacious application of his scientific knowledge to his own needs; and the benefits which he conferred on the natives to whose welfare he devoted himself, and the wonderful influence which he exercised over them, were in no small degree due to the humane and skilled assistance which he was able to render as a healer of bodily disease.  The account which he gave me of his perilous encounter with the lion, and the means he adopted for the repair of the serious injuries which he received, excited the astonishment and admiration of all the medical friends to whom I related it, as evincing an amount of courage, sagacity, skill, and endurance that have scarcely been surpassed in the annals of heroism.”

Another distinguished man of science with whom Livingstone became acquainted in London, and on whom he made an impression similar to that made on Dr. Bennett, was Professor Owen.  Part of the little time at his disposal was devoted to studying the series of comparative anatomy in the Hunterian Museum, under Professor Owen’s charge.  Mr. Owen was interested to find that the Lanarkshire student was born in the same neighborhood as Hunter[17], but still more interested in the youth himself and his great love of natural history.  On taking leave, Livingstone promised to bear his instructor in mind if any curiosity fell in his way.  Years passed, and as no communication reached him, Mr. Owen was disposed to class the promise with too many others made in the like circumstances.  But on his first return to this country Livingstone presented himself, bearing the tusk of an elephant with a spiral curve.  He had found it in the heart of Africa, and it was not easy of transport.  “You may recall,” said Professor Owen, at the Farewell Festival in 1858, “the difficulties of the progress of the weary sick traveler on the bullock’s back.  Every pound weight was of moment; but Livingstone said, ‘Owen shall have this tusk,’ and he placed it in my hands in London.”  Professor Owen recorded this as a proof of Livingstone’s inflexible adherence to his word.  With equal justice we may quote it as a proof of his undying gratitude to any one that had shown him kindness.
