Scotch students have often done wonders in this way, notably the late Dr.John Henderson, a medical missionary to China, who actually lived on half-a-crown a week, while attending medical classes in Edinburgh.
Livingstone followed the same self-denying course.

If we had a note of his house-keeping in his Glasgow lodging, we should wonder less at his ability to live on the fare to which he was often reduced in Africa.
But the importance of the medical qualification had taken a firm hold of his mind, and he persevered in spite of difficulties.

Though it was never his lot to exercise the healing art in China, his medical training was of the highest use in Africa, and it developed wonderfully his strong scientific turn.
[Footnote 8: Livingstone's minister at this time was the Rev.John Moir, of the Congregational church, Hamilton, who afterward joined the Free Church of Scotland, and is now Presbyterian minister in Wellington, New Zealand.

Mr.Moir has furnished us with some recollections of Livingstone, which reached us after the completion of this narrative.

He particularly notes that when Livingstone expressed his desire to be a missionary, it was a missionary out and out, a missionary to the heathen, not the minister of a congregation.
