A serious accident confined Leitch to his room for many months at age 14, during which he studied mathematics and science. After the grammar school at
Greenock, he attended the
University of Glasgow and earned a Bachelor of Arts degree with highest honours in 1837. He followed this with a
Master of Arts the next year, and became
observatory assistant to Professor
John Pringle Nichol, and lectured on astronomy. He then studied for two years at the university's Divinity Hall, and became a licensed minister of the
Church of Scotland in 1839. ==Ministry==
