[2] He studied medicine in London including Anatomy training under Sir Astley Cooper.
[3] He received a commission in the Essex Cavalry as an Army Surgeon around 1796 but appears not to have served abroad and saw service only in Ireland and Scotland.
The regiment moved to the west of Scotland to deal with an issue with the local militia and from there were sent to Ireland to quell the Irish Rebellion of 1798.
However his interests here quickly moved from medicine to botany, becoming a friend of the Edinburgh botanist Patrick Neill.
He died in his house at 13 Inverleith Row, Edinburgh[5] on 17 January 1841 following a ten-day illness,[3] and is buried in St John's Episcopal Churchyard immediately south-west of the church undercroft.
