{129c} About midnight on 28th November, Lord Lyttelton died suddenly in bed, his valet having left him for a moment to fetch a spoon for stirring his medicine.

The cause of death was not stated; there was no inquest.
This, literally, is all that is _known_ about Lord Lyttelton's ghost.
It is variously described as: (1) "a young woman and a robin" (Horace Walpole); (2) "a spirit" (Captain Ascough); (3) a bird in a dream, "which changed into a woman in white" (Lord Westcote's narrative of 13th February, 1780, collected from Lord Lyttelton's guests and servants); (4) "a bird turning into a woman" (Mrs.Delany, 9th December, 1779); (5) a dream of a bird, followed by a woman, Mrs.
Amphlett, in white (Pitt Place archives after 1789); (6) "a fluttering noise, as of a bird, followed by the apparition of a woman who had committed suicide after being seduced by Lyttelton" (Lady Lyttelton, 1828); (7) a bird "which vanished when a female spirit in white raiment presented herself" (Scots Magazine, November-December, 1779).
Out of seven versions, a bird, or a fluttering noise as of a bird (a common feature in ghost stories), {130a} with a woman following or accompanying, occurs in six.

The phenomena are almost equally ascribed to dreaming and to waking hallucination, but the common-sense of the eighteenth century called all ghosts "dreams".

In the Westcote narrative (1780) Lyttelton explains the dream by his having lately been in a room with a lady, Mrs.Dawson, when a robin flew in.

Yet, in the same narrative, Lyttelton says on Saturday morning "that he was very well, and believed he should bilk the _ghost_".
