From Wikipedia:
The Canongate Kirkyard (English: Churchyard) stands around Canongate Kirk on the Royal Mile in Edinburgh, Scotland. The churchyard was used for burials from the late 1680s until the mid-20th century.
The most celebrated burials at the kirkyard are the economist Adam Smith ...
Adam Smith LLD (1723–1790), economist and author of The Wealth of Nations, founded the study of political economics. His house was very close by, at the head of Panmure Close, and it survived until 1889. He lived here from 1778 until his death in 1790, having moved from his native town of Kirkcaldy. The grave is a place of pilgrimage for economists of the world. Although an imposing railed monument, it may have been altered in the 1930s, as it was then described as "too small to notice". It is understood that Dr Joseph Black, the chemist and physicist, and James Hutton, the founder of geology, were both at his funeral, being his executors, as would have been David Douglas ....

My guess is that the stone to the left is the original. Here is a picture:
Does anyone know what it says?
