on's rare technical
skill, scientific knowledge, and unwearying labour have been available
for the purpose.

Amongst almost the last words that Livingstone wrote, I find an
unfinished letter to myself, in which he gives me very clear and
explicit directions concerning the geographical notes he had
previously sent home, and I am but carrying out the sacred duty which
is attached to a last wish when I call attention to the fact, that he
particularly desired in this letter that _no positions gathered from
his observations for latitude and longitude, nor for the levels of the
Lakes, &c., should be considered correct till Sir Thomas Maclear had
examined them_. The position of Casembe's town, and of a point near
Pambette at the S.E., and of Lake Liemba (Tanganyika), have been
computed and corrected by Sir T. Maclear and Dr. Mann. The
observations for latitude were taken at short intervals, and where it
has been possible to test them they have been found very correct, but
I repeat that until the imprimatur of his old friend at the Cape of
Good Hope stands over the whole of Livingstone's work, the map must be
accepted as open to further corrections.

The journey from Kabwabwata to Mparru has been inserted _entirely_
from notes, as the traveller was too ill to mark the route: this is
the only instance in all his wanderings where he failed to give some
indication on his map of the nature of the ground over which he
passed. The journey front Mikindany Bay to Lake Nyassa has also been
laid down from his journal and latitudes in consequence of the section
of this part of his route (which he left at Ujiji) not having arrived
in England at this date.[2] It will be observed that the outline of
Lake Nyassa differs from that on any published map: it has been drawn
from the original exploratory survey of its southern shores made by
Dr. Livingstone in 1861-3. For some reason this original plan was not
adhered to by a former draughtsman, but the Lake has here been
restored to a more accurate bearing and position.

How often shall we see in the pages of this concluding chapter of his
life, that unwavering determination which was pre-eminently the great
characteristic of David Livingstone!

Naturally endowed with unusual endurance, able to concentrate
faculties of no ordinary kind upon whatever he took in hand, and with
a dread of exaggeration which at times almost militated against the
importance of some of his greatest discoveries, it
