(1898)
“ About 1812 the family removed to London, and young Thomson was placed at a boarding-school near Barnet. Having contracted a bronchial affection, he was sent to his uncle's house in Ayrshire, and in October 1813 he entered the university of Glasgow as ‘Thomas Thomson,’ having dropped the ‘Napier’ owing to a disagreement with the Napier family. Thomson was a distinguished student. In 1818 he published a volume, ‘The Immortality of the Soul, and other Poems,’ his only publication in verse. ”
