Alington I am very much indebted for help in the laborious task of deciphering this portion of the Doctor's journals.

Their knowledge of his handwriting, their perseverance, coupled with good eyes and a strong magnifying-glass, at last made their task a complete success.
In comparing this great mass of material with the journal brought home by Mr.Stanley, one finds that a great deal of most interesting matter can be added.

It would seem that in the hurry of writing and copying despatches previous to his companion's departure, the Doctor rapidly entered up as much from his note-books as time and space permitted.
Most fortunately, he still carried the greater part of these original notes till the time of his death, so that they were forthcoming when his effects were subsequently saved.
This brings us to the second instalment of the journals, for we have thus acknowledged the first to have reached us on Mr.Stanley's return.
When the battered tin travelling-case, which was with Livingstone to the last, was opened at the Foreign Office in the spring of this year, not only were these valuable papers disclosed which I have mentioned, but it was found also that Livingstone had kept a copious journal during his stay at Unyanyembe in some copy-books, and that when his stock of note-books was replenished a daily record of his subsequent travels had been made.
It was with fear and trembling that one looked to see whether all had been saved or only part, but with satisfaction and thankfulness I have subsequently discovered that his men preserved every single line, besides his maps, which now come to light for the first time.
Thus much on the material of the diaries: it remains to say a few words on the Map which accompanies these journals.

It has been compiled from Dr.Livingstone's original drawings and note-books, with the corrections and additions he made from time to time as the work of exploration progressed, and the details of physical geography became clearer to him.

The compiler, Mr.John Bolton[1], implicitly following the original outline of the drawing as far as possible, has honestly endeavoured to give such a rendering of the entire work, as the Doctor would have done had he lived to return home, and superintend the construction; and I take this opportunity of expressing my sincere gratification that Mr.Bolton'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_.
