During the 1830s Galbraith became interested in the surveying problems of Scotland.
In 1831 he pointed out that Arthur"s Seat had a strongly magnetic peak. In 1837 he pointed out the impact of anomalies in measurement, work that received recognition.
lieutenant was topical because of the 1836 geological map of Scotland by John MacCulloch, with which critics had found fault on topographical as well as geological grounds.
