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
