_Ghost Stories_ (Vol. iv., p. 5.; Vol. v., p. 89.).--Baron Reichenbach
has evidently overrated the importance of his discovery, but his system
may be advantageously applied to the explanation of corpse-candles,
illuminated church-yards, and other articles of Welsh and English
superstition. Aubrey tells us, that "when any Christian is drowned in
the river Dee, there will appear over the water where the corpse is a
light, by which means they do find the body." The Welsh also to this day
believe that the body of a secretly buried person may be discovered by
the lambent blue flame which hovers round the grave at night.
I would also refer DR. MAITLAND to Baxter's _Certainty of the World of
Spirits_, and the chapter on "Spectral Lights" in Mrs. Crowe's
_Night-side of Nature_.
