Summary:

Delayed writing following death of Smith's mother. The King [George IV (1762-1830)] almost died but is now recovering, dropsy was avoided after he lost 130 ounces of blood, the illness not caused by intemperance but was the same kind which killed the Duke of Kent [pneumonia]. Thinks ministers acted generously and wisely dissolving Parliament so early. A new Linnean dining club established at the Thatched House Tavern, dismisses concerns that it will cause a schism with those attending the club held at the British Coffee House. Two children of his son, Robert, died of whooping cough, his daughter Charlotte's ten children all had it but survived, she is now expecting her eleventh.
