species were homologous; although he believed the succession of species showed progress over time, he did not believe that later species were descended from earlier ones. He denied the Epicurean theory that new species occasionally budded from the soil, and the Lamarckian theory of development of species, as lacking evidence. He argued that all this showed the direct action of a benevolent Creator, as attested in the Bible – the similarities of species are manifestations of types in the Divine Mind; he accepted the view of Thomas Chalmers that Genesis begins with an account of geological periods, and does not mean that each of them is a day; Noah's Flood was a limited subsidence of the Middle East. Geology, to Miller, offered a better version of the argument from design than William Paley could provide, and answered the objections of sceptics, by showing that living species did not arise by chance or by impersonal law. In a biographical review about him, he was recognized as an exceptional person by Sir David Brewster, who said of him: Illness and death For most of 1856, Miller had severe headaches and mental distress, and the most probable diagnosis is of psychotic depression. Victorian medicine did not help. He feared that he might harm his wife or children because of persecutory delusions. Miller died by suicide, shooting himself in the chest with a revolver in his house, Shrub Mount, Portobello, on the night of 23/24 December 1856. That night he had finished checking printers' proofs for his book on geology and Christianity, The Testimony of the Rocks. Before his death, he wrote a poem called Strange but True. He died on 24 December 1856. His funeral procession, attended by thousands, was amongst the largest in the memory of Edinburgh residents. He is buried in the Grange Cemetery in Edinburgh. His is a simple red granite monument on the north boundary wall, close to the northwest corner. His son Hugh Miller FRSE (1850-1896), who was six years old when his father killed himself, lies on his left side. Legacy Though he had no academic credentials, he is today considered one of Scotland's most influential Victorian palaeontologists, particularly in communicating science to a wider audience. Miller made many new discoveries, including several Silurian sea scorpions (the eurypterid genus Hughmilleria was named in his honour), and many Devonian fishes, including several placoderms (the arthrodire Millerosteus also honoured
