In this way, too, he became acquainted with the late Dr.George Wilson, afterward Professor of Technology in the University of Edinburgh, who was then acting as unsalaried assistant in Dr.Graham's laboratory.

Frank, genial, and chivalrous, Wilson and Livingstone had much in common, and more in after-years, when Wilson, too, became an earnest Christian.

In the simplicity and purity of their character, and in their devotion to science, not only for its own sake, but as a department of the kingdom of God, they were brothers indeed.

Livingstone showed his friendship in after-years by collecting and transmitting to Wilson whatever he could find in Africa worthy of a place in the Edinburgh Museum of Science and Art, of which his friend was the first Director.
In the course of his second session in Glasgow (1837-38) Livingstone applied to the London Missionary Society, offering his services to them as a missionary.

He had learned that that Society had for its sole object to send the gospel to the heathen; that it accepted missionaries from different Churches, and that it did not set up any particular form of Church, but left it to the converts to choose the form they considered most in accordance with the Word of God.
