He was an active member of the Stirling Field and Archaeological Society and it was they who published his 'Recollections' - by far the most extensive such personal account for the town. The text, with a photo, brief introduction and notes, has now been posted on the Stirling Local History Society website, where it will be much more accessible.
The recollections cover matters from demographic changes to funeral protocol, church services to the impact of the railway. They can now be found (with some explanatory notes) at https://www.stirling-lhs.org/dr-gt-galbraith.html
