Abstract
Chris McManus' scholarly book Right Hand, Left Hand begins with the story of John Reid, who died in London in 1835, at the age of 48. The post-mortem was carried out by Dr. Thomas Watson who discovered that John Reid's heart was on the wrong side, that is, on the right side. In fact, all of his organs were reversed, with the liver on the left and stomach on the right, etc. This was the first modern scientific evidence of a condition known as situs inversus.
