How a life changed with a friend’s carelessness

The Heddle Family in around 1890

“Thinking over his loss he determined to relinquish botany as a special study and to devote himself to geology and mineralogy, which determination he never afterwards regretted,” wrote David Douglas in his 1901 book, The Mineralogy of Scotland.

Heddle went on to teach mineralogy at St Andrews, spending every summer exploring Scotland’s rocks: “Few parts of Scotland and its adjacent Islands… were unvisited and unexplored… The slitting of agates, rocks and minerals for specimens and microscopic slides, which he did actually by thousands amid all his other work, was little less than marvellous…”
